Randy brought it to my attention that in proper english "can not" should always be written "cannot". I donot see any reason to argue, even if I mightnot understand why this rule exists. This patch fixes "can not" in several Documentation files as well as three Kconfigs.

INTRODUCTION TO ARCNET
|
|
----------------------
|
|
|
|
ARCnet is a network type which works in a way similar to popular Ethernet
|
|
networks but which is also different in some very important ways.
|
|
|
|
First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps
|
|
(slower than Ethernet) and 100 Mbps (faster than normal Ethernet). In fact,
|
|
there are others as well, but these are less common. The different hardware
|
|
types, as far as I'm aware, are not compatible and so you cannot wire a
|
|
100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does
|
|
work with 100 Mbps cards, but I haven't been able to verify this myself,
|
|
since I only have the 2.5 Mbps variety. It is probably not going to saturate
|
|
your 100 Mbps card. Stop complaining. :)
|
|
|
|
You also cannot connect an ARCnet card to any kind of Ethernet card and
|
|
expect it to work.
|
|
|
|
There are two "types" of ARCnet - STAR topology and BUS topology. This
|
|
refers to how the cards are meant to be wired together. According to most
|
|
available documentation, you can only connect STAR cards to STAR cards and
|
|
BUS cards to BUS cards. That makes sense, right? Well, it's not quite
|
|
true; see below under "Cabling."
|
|
|
|
Once you get past these little stumbling blocks, ARCnet is actually quite a
|
|
well-designed standard. It uses something called "modified token passing"
|
|
which makes it completely incompatible with so-called "Token Ring" cards,
|
|
but which makes transfers much more reliable than Ethernet does. In fact,
|
|
ARCnet will guarantee that a packet arrives safely at the destination, and
|
|
even if it can't possibly be delivered properly (ie. because of a cable
|
|
break, or because the destination computer does not exist) it will at least
|
|
tell the sender about it.
|
|
|
|
Because of the carefully defined action of the "token", it will always make
|
|
a pass around the "ring" within a maximum length of time. This makes it
|
|
useful for realtime networks.
|
|
|
|
In addition, all known ARCnet cards have an (almost) identical programming
|
|
interface. This means that with one ARCnet driver you can support any
|
|
card, whereas with Ethernet each manufacturer uses what is sometimes a
|
|
completely different programming interface, leading to a lot of different,
|
|
sometimes very similar, Ethernet drivers. Of course, always using the same
|
|
programming interface also means that when high-performance hardware
|
|
facilities like PCI bus mastering DMA appear, it's hard to take advantage of
|
|
them. Let's not go into that.
|
|
|
|
One thing that makes ARCnet cards difficult to program for, however, is the
|
|
limit on their packet sizes; standard ARCnet can only send packets that are
|
|
up to 508 bytes in length. This is smaller than the Internet "bare minimum"
|
|
of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra
|
|
level of encapsulation is defined by RFC1201, which I call "packet
|
|
splitting," that allows "virtual packets" to grow as large as 64K each,
|
|
although they are generally kept down to the Ethernet-style 1500 bytes.
|
|
|
|

|
|
advantages) of ARCnet networks, you might try the "ARCnet Trade Association"

CABLING ARCNET NETWORKS
|
|
-----------------------
|
|
|
|
This section was rewritten by
|
|
Vojtech Pavlik <vojtech@suse.cz>
|
|
using information from several people, including:
|
|
Avery Pennraun <apenwarr@worldvisions.ca>
|
|
Stephen A. Wood <saw@hallc1.cebaf.gov>
|
|
John Paul Morrison <jmorriso@bogomips.ee.ubc.ca>
|
|
Joachim Koenig <jojo@repas.de>
|
|
and Avery touched it up a bit, at Vojtech's request.
|
|
|
|
ARCnet (the classic 2.5 Mbps version) can be connected by two different
|
|
types of cabling: coax and twisted pair. The other ARCnet-type networks
|
|
(100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of
|
|
cabling (Type1, Fiber, C1, C4, C5).
|
|
|
|
For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables
|
|
also work fine, because ARCnet is a very stable network. I personally use 75
|
|
Ohm TV antenna cable.
|
|
|
|
Cards for coax cabling are shipped in two different variants: for BUS and
|
|
STAR network topologies. They are mostly the same. The only difference
|
|
lies in the hybrid chip installed. BUS cards use high impedance output,
|
|
while STAR use low impedance. Low impedance card (STAR) is electrically
|
|
equal to a high impedance one with a terminator installed.
|
|
|
|
Usually, the ARCnet networks are built up from STAR cards and hubs. There
|
|
are two types of hubs - active and passive. Passive hubs are small boxes
|
|
with four BNC connectors containing four 47 Ohm resistors:
|
|
|
|
| | wires
|
|
R + junction
|
|
-R-+-R- R 47 Ohm resistors
|
|
R
|
|
|
|
|
|
|
The shielding is connected together. Active hubs are much more complicated;
|
|
they are powered and contain electronics to amplify the signal and send it
|
|
to other segments of the net. They usually have eight connectors. Active
|
|
hubs come in two variants - dumb and smart. The dumb variant just
|
|
amplifies, but the smart one decodes to digital and encodes back all packets
|
|
coming through. This is much better if you have several hubs in the net,
|
|
since many dumb active hubs may worsen the signal quality.
|
|
|
|
And now to the cabling. What you can connect together:
|
|
|
|
1. A card to a card. This is the simplest way of creating a 2-computer
|
|
network.
|
|
|
|
2. A card to a passive hub. Remember that all unused connectors on the hub
|
|
must be properly terminated with 93 Ohm (or something else if you don't
|
|
have the right ones) terminators.
|
|
(Avery's note: oops, I didn't know that. Mine (TV cable) works
|
|
anyway, though.)
|
|
|
|
3. A card to an active hub. Here is no need to terminate the unused
|
|
connectors except some kind of aesthetic feeling. But, there may not be
|
|
more than eleven active hubs between any two computers. That of course
|
|
doesn't limit the number of active hubs on the network.
|
|
|
|
4. An active hub to another.
|
|
|
|
5. An active hub to passive hub.
|
|
|
|
Remember that you cannot connect two passive hubs together. The power loss
|
|
implied by such a connection is too high for the net to operate reliably.
|
|
|
|
An example of a typical ARCnet network:
|
|
|
|
R S - STAR type card
|
|
S------H--------A-------S R - Terminator
|
|
| | H - Hub
|
|
| | A - Active hub
|
|
| S----H----S
|
|
S |
|
|
|
|
|
S
|
|
|
|
The BUS topology is very similar to the one used by Ethernet. The only
|
|
difference is in cable and terminators: they should be 93 Ohm. Ethernet
|
|
uses 50 Ohm impedance. You use T connectors to put the computers on a single
|
|
line of cable, the bus. You have to put terminators at both ends of the
|
|
cable. A typical BUS ARCnet network looks like:
|
|
|
|
RT----T------T------T------T------TR
|
|
B B B B B B
|
|
|
|
B - BUS type card
|
|
R - Terminator
|
|
T - T connector
|
|
|
|
But that is not all! The two types can be connected together. According to
|
|
the official documentation the only way of connecting them is using an active
|
|
hub:
|
|
|
|
A------T------T------TR
|
|
| B B B
|
|
S---H---S
|
|
|
|
|
S
|
|
|
|
The official docs also state that you can use STAR cards at the ends of
|
|
BUS network in place of a BUS card and a terminator:
|
|
|
|
S------T------T------S
|
|
B B
|
|
|
|
But, according to my own experiments, you can simply hang a BUS type card
|
|
anywhere in middle of a cable in a STAR topology network. And more - you
|
|
can use the bus card in place of any star card if you use a terminator. Then
|
|
you can build very complicated networks fulfilling all your needs! An
|
|
example:
|
|
|
|
S
|
|
|
|
|
RT------T-------T------H------S
|
|
B B B |
|
|
| R
|
|
S------A------T-------T-------A-------H------TR
|
|
| B B | | B
|
|
| S BT |
|
|
| | | S----A-----S
|
|
S------H---A----S | |
|
|
| | S------T----H---S |
|
|
S S B R S
|
|
|
|
A basically different cabling scheme is used with Twisted Pair cabling. Each
|
|
of the TP cards has two RJ (phone-cord style) connectors. The cards are
|
|
then daisy-chained together using a cable connecting every two neighboring
|
|
cards. The ends are terminated with RJ 93 Ohm terminators which plug into
|
|
the empty connectors of cards on the ends of the chain. An example:
|
|
|
|
___________ ___________
|
|
_R_|_ _|_|_ _|_R_
|
|
| | | | | |
|
|
|Card | |Card | |Card |
|
|
|_____| |_____| |_____|
|
|
|
|
|
|
There are also hubs for the TP topology. There is nothing difficult
|
|
involved in using them; you just connect a TP chain to a hub on any end or
|
|
even at both. This way you can create almost any network configuration.
|
|
The maximum of 11 hubs between any two computers on the net applies here as
|
|
well. An example:
|
|
|
|
RP-------P--------P--------H-----P------P-----PR
|
|
|
|
|
RP-----H--------P--------H-----P------PR
|
|
| |
|
|
PR PR
|
|
|
|
R - RJ Terminator
|
|
P - TP Card
|
|
H - TP Hub
|
|
|
|
Like any network, ARCnet has a limited cable length. These are the maximum
|
|
cable lengths between two active ends (an active end being an active hub or
|
|
a STAR card).
|
|
|
|
RG-62 93 Ohm up to 650 m
|
|
RG-59/U 75 Ohm up to 457 m
|
|
RG-11/U 75 Ohm up to 533 m
|
|
IBM Type 1 150 Ohm up to 200 m
|
|
IBM Type 3 100 Ohm up to 100 m
|
|
|
|
The maximum length of all cables connected to a passive hub is limited to 65
|
|
meters for RG-62 cabling; less for others. You can see that using passive
|
|
hubs in a large network is a bad idea. The maximum length of a single "BUS
|
|
Trunk" is about 300 meters for RG-62. The maximum distance between the two
|
|
most distant points of the net is limited to 3000 meters. The maximum length
|
|
of a TP cable between two cards/hubs is 650 meters.
|
|
|
|
|
|
SETTING THE JUMPERS
|
|
-------------------
|
|
|
|
All ARCnet cards should have a total of four or five different settings:
|
|
|
|
- the I/O address: this is the "port" your ARCnet card is on. Probed
|
|
values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If
|
|
your card has additional ones, which is possible, please tell me.) This
|
|
should not be the same as any other device on your system. According to
|
|
a doc I got from Novell, MS Windows prefers values of 0x300 or more,
|
|
eating net connections on my system (at least) otherwise. My guess is
|
|
this may be because, if your card is at 0x2E0, probing for a serial port
|
|
at 0x2E8 will reset the card and probably mess things up royally.
|
|
- Avery's favourite: 0x300.
|
|
|
|
- the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
|
|
on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
|
|
|
|
Make sure this is different from any other card on your system. Note
|
|
that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can
|
|
"cat /proc/interrupts" for a somewhat complete list of which ones are in
|
|
use at any given time. Here is a list of common usages from Vojtech
|
|
Pavlik <vojtech@suse.cz>:
|
|
("Not on bus" means there is no way for a card to generate this
|
|
interrupt)
|
|
IRQ 0 - Timer 0 (Not on bus)
|
|
IRQ 1 - Keyboard (Not on bus)
|
|
IRQ 2 - IRQ Controller 2 (Not on bus, nor does interrupt the CPU)
|
|
IRQ 3 - COM2
|
|
IRQ 4 - COM1
|
|
IRQ 5 - FREE (LPT2 if you have it; sometimes COM3; maybe PLIP)
|
|
IRQ 6 - Floppy disk controller
|
|
IRQ 7 - FREE (LPT1 if you don't use the polling driver; PLIP)
|
|
IRQ 8 - Realtime Clock Interrupt (Not on bus)
|
|
IRQ 9 - FREE (VGA vertical sync interrupt if enabled)
|
|
IRQ 10 - FREE
|
|
IRQ 11 - FREE
|
|
IRQ 12 - FREE
|
|
IRQ 13 - Numeric Coprocessor (Not on bus)
|
|
IRQ 14 - Fixed Disk Controller
|
|
IRQ 15 - FREE (Fixed Disk Controller 2 if you have it)
|
|
|
|
Note: IRQ 9 is used on some video cards for the "vertical retrace"
|
|
interrupt. This interrupt would have been handy for things like
|
|
video games, as it occurs exactly once per screen refresh, but
|
|
unfortunately IBM cancelled this feature starting with the original
|
|
VGA and thus many VGA/SVGA cards do not support it. For this
|
|
reason, no modern software uses this interrupt and it can almost
|
|
always be safely disabled, if your video card supports it at all.
|
|
|
|
If your card for some reason CANNOT disable this IRQ (usually there
|
|
is a jumper), one solution would be to clip the printed circuit
|
|
contact on the board: it's the fourth contact from the left on the
|
|
back side. I take no responsibility if you try this.
|
|
|
|
- Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though.
|
|
|
|
- the memory address: Unlike most cards, ARCnets use "shared memory" for
|
|
copying buffers around. Make SURE it doesn't conflict with any other
|
|
used memory in your system!
|
|
A0000 - VGA graphics memory (ok if you don't have VGA)
|
|
B0000 - Monochrome text mode
|
|
C0000 \ One of these is your VGA BIOS - usually C0000.
|
|
E0000 /
|
|
F0000 - System BIOS
|
|
|
|
Anything less than 0xA0000 is, well, a BAD idea since it isn't above
|
|
640k.
|
|
- Avery's favourite: 0xD0000
|
|
|
|
- the station address: Every ARCnet card has its own "unique" network
|
|
address from 0 to 255. Unlike Ethernet, you can set this address
|
|
yourself with a jumper or switch (or on some cards, with special
|
|
software). Since it's only 8 bits, you can only have 254 ARCnet cards
|
|
on a network. DON'T use 0 or 255, since these are reserved (although
|
|
neat stuff will probably happen if you DO use them). By the way, if you
|
|
haven't already guessed, don't set this the same as any other ARCnet on
|
|
your network!
|
|
- Avery's favourite: 3 and 4. Not that it matters.
|
|
|
|
- There may be ETS1 and ETS2 settings. These may or may not make a
|
|
difference on your card (many manuals call them "reserved"), but are
|
|
used to change the delays used when powering up a computer on the
|
|
network. This is only necessary when wiring VERY long range ARCnet
|
|
networks, on the order of 4km or so; in any case, the only real
|
|
requirement here is that all cards on the network with ETS1 and ETS2
|
|
jumpers have them in the same position. Chris Hindy <chrish@io.org>
|
|
sent in a chart with actual values for this:
|
|
ET1 ET2 Response Time Reconfiguration Time
|
|
--- --- ------------- --------------------
|
|
open open 74.7us 840us
|
|
open closed 283.4us 1680us
|
|
closed open 561.8us 1680us
|
|
closed closed 1118.6us 1680us
|
|
|
|
Make sure you set ETS1 and ETS2 to the SAME VALUE for all cards on your
|
|
network.
|
|
|
|
Also, on many cards (not mine, though) there are red and green LED's.
|
|
Vojtech Pavlik <vojtech@suse.cz> tells me this is what they mean:
|
|
GREEN RED Status
|
|
----- --- ------
|
|
OFF OFF Power off
|
|
OFF Short flashes Cabling problems (broken cable or not
|
|
terminated)
|
|
OFF (short) ON Card init
|
|
ON ON Normal state - everything OK, nothing
|
|
happens
|
|
ON Long flashes Data transfer
|
|
ON OFF Never happens (maybe when wrong ID)
|
|
|
|
|
|
The following is all the specific information people have sent me about
|
|
their own particular ARCnet cards. It is officially a mess, and contains
|
|
huge amounts of duplicated information. I have no time to fix it. If you
|
|
want to, PLEASE DO! Just send me a 'diff -u' of all your changes.
|
|
|
|
The model # is listed right above specifics for that card, so you should be
|
|
able to use your text viewer's "search" function to find the entry you want.
|
|
If you don't KNOW what kind of card you have, try looking through the
|
|
various diagrams to see if you can tell.
|
|
|
|
If your model isn't listed and/or has different settings, PLEASE PLEASE
|
|
tell me. I had to figure mine out without the manual, and it WASN'T FUN!
|
|
|
|
Even if your ARCnet model isn't listed, but has the same jumpers as another
|
|
model that is, please e-mail me to say so.

About the jumpers: On my PC130 there is one more jumper, located near the
|
|
cable-connector and it's for changing to star or bus topology;
|
|
closed: star - open: bus
|
|
On the PC500 are some more jumper-pins, one block labeled with RX,PDN,TXI
|
|
and another with ALE,LA17,LA18,LA19 these are undocumented..

-------------------
|
|
|
|
The eight switches in group S2 are used to set the node ID.
|
|
These switches work in a way similar to the PC100-series cards; see that
|
|
entry for more information.
|
|
|
|
|
|
Setting the I/O Base Address
|
|
----------------------------
|
|
|
|
The first three switches in switch group S1 are used to select one
|
|
of eight possible I/O Base addresses using the following table

|
|
16K block can be located in any of eight positions.
|
|
Switches 4-6 of switch group S1 select the Base of the 16K block.
|
|
Within that 16K address space, the buffer may be assigned any one of four
|
|
positions, determined by the offset, switches 7 and 8 of group S1.

*) To enable the 8K Boot PROM install the jumper ROM.
|
|
The default is jumper ROM not installed.
|
|
|
|
|
|
Setting the Timeouts and Interrupt
|
|
----------------------------------
|
|
|
|
The jumpers labeled EXT1 and EXT2 are used to determine the timeout
|
|
parameters. These two jumpers are normally left open.
|
|
|
|
To select a hardware interrupt level set one (only one!) of the jumpers
|
|
IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2.
|
|
|
|
|
|
Configuring the PC130E for Star or Bus Topology
|
|
-----------------------------------------------
|
|
|
|
The single jumper labeled STAR is used to configure the PC130E board for
|
|
star or bus topology.
|
|
When the jumper is installed, the board may be used in a star network, when
|
|
it is removed, the board can be used in a bus topology.
|
|
|
|
|
|
Diagnostic LEDs
|
|
---------------
|
|
|
|
Two diagnostic LEDs are visible on the rear bracket of the board.
|
|
The green LED monitors the network activity: the red one shows the
|
|
board activity:
|
|
|
|
Green | Status Red | Status
|
|
-------|------------------- ---------|-------------------
|
|

STANDARD MICROSYSTEMS CORPORATION (SMC) ARCNET-PC500/PC550 Long Board
|
|
=====================================================================
|
|
|
|
Note: There is another Version of the PC500 called Short Version, which
|
|
is different in hard- and software! The most important differences
|
|
are:
|
|
- The long board has no Shared memory.
|
|
- On the long board the selection of the interrupt is done by binary
|
|
coded switch, on the short board directly by jumper.
|
|
|
|
[Avery's note: pay special attention to that: the long board HAS NO SHARED
|
|
MEMORY. This means the current Linux-ARCnet driver can't use these cards.
|
|
I have obtained a PC500Longboard and will be doing some experiments on it in
|
|
the future, but don't hold your breath. Thanks again to Juergen Seifert for
|
|
his advice about this!]

|
|
|
|
The eight switches in group SW3 are used to set the node ID. Each node
|
|
attached to the network must have an unique node ID which must be
|
|
different from 0.
|
|
Switch 1 serves as the least significant bit (LSB).
|
|
|
|
The node ID is the sum of the values of all switches set to "1"
|
|
These values are:

Setting the Interrupt
|
|
---------------------
|
|
|
|
Switches seven through ten of switch group SW1 are used to select the
|
|
interrupt level. The interrupt level is binary coded, so selections
|
|
from 0 to 15 would be possible, but only the following eight values will
|
|
be supported: 3, 4, 5, 7, 9, 10, 11, 12.

The two jumpers JP2 (1-4) are used to determine the timeout parameters.
|
|
These two jumpers are normally left open.
|
|
Refer to the COM9026 Data Sheet for alternate configurations.

Configuring the PC500 for Star or Bus Topology
|
|
----------------------------------------------
|
|
|
|
The single jumper labeled JP6 is used to configure the PC500 board for
|
|
star or bus topology.
|
|
When the jumper is installed, the board may be used in a star network, when
|
|
it is removed, the board can be used in a bus topology.
|
|
|
|
|
|
Diagnostic LEDs
|
|
---------------
|
|
|
|
Two diagnostic LEDs are visible on the rear bracket of the board.
|
|
The green LED monitors the network activity: the red one shows the
|
|
board activity:

|
|
|
|
Note: this data is gathered by experimenting and looking at info of other
|
|
cards. However, I'm sure I got 99% of the settings right.
|
|
|
|
The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
|
|
LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing:

The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
|
|
labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
|
|
IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
|
|
|
|
S1 and S2 perform the same function as on the PC270, only their numbers
|
|
are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
|
|
|
|
I know it works when connected to a PC110 type ARCnet board.

LCS-8830(-T) (8 and 16-bit cards)
|
|
---------------------------------
|
|
- from Mathias Katzer <mkatzer@HRZ.Uni-Bielefeld.DE>
|
|
- Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl> says the
|
|
LCS-8830 is slightly different from LCS-8830-T. These are 8 bit, BUS
|
|
only (the JP0 jumper is hardwired), and BNC only.
|
|
|
|
This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC,
|
|
nowhere else, not even on the few Xeroxed sheets from the manual).

PDI507 (8-bit card)
|
|
--------------------
|
|
- from Mark Rejhon <mdrejhon@magi.com> (slight modifications by Avery)
|
|
- Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
|
|
are mostly the same as this. PDI508Plus cards appear to be mainly
|
|
software-configured.
|
|
|
|
Jumpers:
|
|
There is a jumper array at the bottom of the card, near the edge
|
|
connector. This array is labelled J1. They control the IRQs and
|
|
something else. Put only one jumper on the IRQ pins.
|
|
|
|
ETS1, ETS2 are for timing on very long distance networks. See the
|
|
more general information near the top of this file.
|
|
|
|
There is a J2 jumper on two pins. A jumper should be put on them,
|
|
since it was already there when I got the card. I don't know what
|
|
this jumper is for though.
|
|
|
|
There is a two-jumper array for J3. I don't know what it is for,
|
|
but there were already two jumpers on it when I got the card. It's
|
|
a six pin grid in a two-by-three fashion. The jumpers were
|
|
configured as follows:
|
|
|
|

|
- If using coax cable in a bus topology the J4 jumper must be removed;
|
|
place it on one pin.
|
|
|
|
- If using bus topology with twisted pair wiring move the J3
|
|
jumpers so they connect the middle pin and the pins closest to the RJ11
|
|
Connectors. Also the J4 jumper must be removed; place it on one pin of
|
|
J4 jumper for storage.
|
|
|
|
- If using star topology with twisted pair wiring move the J3
|
|
jumpers so they connect the middle pin and the pins closest to the RJ11
|
|
connectors.
|
|
|
|
|
|
DIP Switches:
|
|
|
|
The DIP switches accessible on the accessible end of the card while
|
|
it is installed, is used to set the ARCnet address. There are 8
|
|
switches. Use an address from 1 to 254.
|
|
|
|
Switch No.
|
|

|
|
11111110 1
|
|
11111111 0 (Don't use this!)
|
|
|
|
There is another array of eight DIP switches at the top of the
|
|
card. There are five labelled MS0-MS4 which seem to control the
|
|
memory address, and another three labelled IO0-IO2 which seem to
|
|
control the base I/O address of the card.
|
|
|
|
This was difficult to test by trial and error, and the I/O addresses
|
|
are in a weird order. This was tested by setting the DIP switches,
|
|
rebooting the computer, and attempting to load ARCETHER at various
|
|
addresses (mostly between 0x200 and 0x400). The address that caused
|
|
the red transmit LED to blink, is the one that I thought works.
|
|
|
|
Also, the address 0x3D0 seem to have a special meaning, since the
|
|
ARCETHER packet driver loaded fine, but without the red LED
|
|
blinking. I don't know what 0x3D0 is for though. I recommend using
|
|
an address of 0x300 since Windows may not like addresses below
|
|
0x300.
|
|
|
|
IO Switch No.
|
|

|
111 0x260
|

110 0x290

100 0x2F0

011 0x300
|
|
010 0x350
|
|
001 0x380
|
|
000 0x3E0
|
|
|
|
The memory switches set a reserved address space of 0x1000 bytes
|
|
(0x100 segment units, or 4k). For example if I set an address of
|
|
0xD000, it will use up addresses 0xD000 to 0xD100.
|
|
|
|
The memory switches were tested by booting using QEMM386 stealth,
|
|
and using LOADHI to see what address automatically became excluded
|
|
from the upper memory regions, and then attempting to load ARCETHER
|
|
using these addresses.
|
|
|
|
I recommend using an ARCnet memory address of 0xD000, and putting
|
|
the EMS page frame at 0xC000 while using QEMM stealth mode. That
|
|
way, you get contiguous high memory from 0xD100 almost all the way
|
|
the end of the megabyte.
|
|
|
|
Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
|
|
on my card. It could be malfunctioning on my card. Experiment with
|
|
it ON first, and if it doesn't work, set it to OFF. (It may be a
|
|
modifier for the 0x200 bit?)
|
|
|
|
MS Switch No.

Setting the Node ID
|
|
-------------------
|
|
|
|
The eight switches in SW2 are used to set the node ID. Each node attached
|
|
to the network must have an unique node ID which must be different from 0.
|
|
Switch 1 (ID0) serves as the least significant bit (LSB).
|
|
|
|
The node ID is the sum of the values of all switches set to "1"
|
|
These values are:
|
|
|
|
Switch | Label | Value
|
|
-------|-------|-------
|
|
1 | ID0 | 1
|
|
2 | ID1 | 2

Setting the I/O Base Address
|
|
----------------------------
|
|
|
|
The last three switches in switch block SW1 are used to select one
|
|
of eight possible I/O Base addresses using the following table
|
|
|
|
|
|
Switch | Hex I/O
|
|
6 7 8 | Address
|
|
------------|--------
|
|
ON ON ON | 260
|
|

|
|
ON OFF ON | 2E0 (Manufacturer's default)
|
|
OFF OFF ON | 2F0
|
|
ON ON OFF | 300
|
|
OFF ON OFF | 350
|
|
ON OFF OFF | 380
|
|
OFF OFF OFF | 3E0
|
|
|
|
|
|
Setting the Base Memory (RAM) buffer Address
|
|
--------------------------------------------
|
|
|
|
The memory buffer (RAM) requires 2K. The base of this buffer can be
|
|
located in any of eight positions. The address of the Boot Prom is
|
|
memory base + 8K or memory base + 0x2000.
|
|
Switches 1-5 of switch block SW1 select the Memory Base address.
|
|
|
|
Switch | Hex RAM | Hex ROM

Setting the Node ID
|
|
-------------------
|
|
|
|
The eight switches in SW2 are used to set the node ID. Each node attached
|
|
to the network must have an unique node ID which must be different from 0.
|
|
Switch 1 (ID0) serves as the least significant bit (LSB).
|
|
|
|
The node ID is the sum of the values of all switches set to "1"
|
|
These values are:
|
|
|
|
Switch | Label | Value
|
|
-------|-------|-------
|
|
1 | ID0 | 1
|
|
2 | ID1 | 2

|
|
|
|
Note: - Do not use JP11=IRQ6, it may conflict with your Floppy Disk
|
|
Controller
|
|
- Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
|
|
Hard Disk, it may conflict with their controllers
|
|
|
|
|
|

It seems that the bits are considered in reverse order. Also, you must
|
|
observe that some of those addresses are unusual and I didn't probe them; I
|
|
used a memory dump in DOS to identify them. For the 00000 configuration and
|
|
some others that I didn't write here the card seems to conflict with the
|
|
video card (an S3 GENDAC). I leave the full decoding of those addresses to
|
|
you.

Setting the Node ID
|
|
-------------------
|
|
|
|
The eight switches in SW2 are used to set the node ID. Each node attached
|
|
to the network must have an unique node ID which must not be 0.
|
|
Switch 1 (ID0) serves as the least significant bit (LSB).
|
|
|
|
Setting one of the switches to OFF means "1", ON means "0".
|
|
|
|
The node ID is the sum of the values of all switches set to "1"
|
|
These values are:
|
|
|
|
Switch | Value
|
|
-------|-------
|
|
1 | 1
|
|
2 | 2
|
|
3 | 4
|
|
4 | 8
|
|
5 | 16
|
|
6 | 32
|
|
7 | 64
|
|
8 | 128
|
|
|
|
Don't set this to 0 or 255; these values are reserved.
|
|
|
|
|
|
Setting the I/O Base Address
|
|
----------------------------
|
|
|
|
The switches 1 to 6 of switch block SW1 are used to select one
|
|
of 32 possible I/O Base addresses using the following tables
|
|
|
|
| Hex
|
|
Switch | Value
|
|
-------|-------
|
|
1 | 200
|
|
2 | 100
|
|
3 | 80
|
|
4 | 40
|
|
5 | 20
|
|
6 | 10
|
|
|
|
The I/O address is sum of all switches set to "1". Remember that
|
|
the I/O address space bellow 0x200 is RESERVED for mainboard, so
|
|
switch 1 should be ALWAYS SET TO OFF.
|
|
|
|
|
|
Setting the Base Memory (RAM) buffer Address
|
|
--------------------------------------------
|
|
|
|
The memory buffer (RAM) requires 2K. The base of this buffer can be
|
|
located in any of sixteen positions. However, the addresses below
|
|
A0000 are likely to cause system hang because there's main RAM.
|
|
|
|
Jumpers 7-10 of switch block SW1 select the Memory Base address.
|
|
|
|
Switch | Hex RAM
|
|
7 8 9 10 | Address
|
|
----------------|---------
|
|
OFF OFF OFF OFF | F0000 (conflicts with main BIOS)
|
|
OFF OFF OFF ON | E0000
|
|
OFF OFF ON OFF | D0000
|
|
OFF OFF ON ON | C0000 (conflicts with video BIOS)
|
|
OFF ON OFF OFF | B0000 (conflicts with mono video)
|
|
OFF ON OFF ON | A0000 (conflicts with graphics)
|
|
|
|
|
|
Setting the Interrupt Line
|
|
--------------------------
|
|
|
|
Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
|
|
shorted, OFF means open.
|
|
|
|
Jumper | IRQ
|
|
1 2 3 4 5 |
|
|
----------------------------
|
|
ON OFF OFF OFF OFF | 7
|
|
OFF ON OFF OFF OFF | 5
|
|
OFF OFF ON OFF OFF | 4
|
|
OFF OFF OFF ON OFF | 3
|
|
OFF OFF OFF OFF ON | 2
|
|
|
|
|
|
Unknown jumpers & sockets
|
|
-------------------------
|
|
|
|
I know nothing about these. I just guess that J16&J17 are timeout
|
|
jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
|
|
J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't
|
|
guess the purpose.

Setting the Node ID
|
|
-------------------
|
|
|
|
The eight switches in SW3 are used to set the node ID. Each node attached
|
|
to the network must have an unique node ID which must not be 0.
|
|
Switch 1 serves as the least significant bit (LSB).
|
|
|
|
Setting one of the switches to Off means "1", On means "0".
|
|
|
|
The node ID is the sum of the values of all switches set to "1"
|
|
These values are:
|
|
|
|
Switch | Value
|
|
-------|-------
|
|
1 | 1

|
Setting the I/O Base Address
|
|
----------------------------
|
|
|
|
The last three switches in switch block SW1 are used to select one
|
|
of eight possible I/O Base addresses using the following table
|
|
|
|
|
|
Switch | Hex I/O
|
|

Setting the Base Memory (RAM) buffer Address
|
|
--------------------------------------------
|
|
|
|
The memory buffer (RAM) requires 2K. The base of this buffer can be
|
|
located in any of eight positions. The address of the Boot Prom is
|
|
memory base + 0x2000.
|
|
Jumpers 3-5 of switch block SW1 select the Memory Base address.
|
|
|
|
Switch | Hex RAM | Hex ROM

|
|
|
|
*) To enable the Boot ROM set the switch 8 of switch block SW3 to position ON.
|
|
|
|
The switches 1 and 2 probably add 0x0800 and 0x1000 to RAM base address.
|
|
|
|
|
|
Setting the Interrupt Line
|
|
--------------------------
|
|
|
|
Switches 1-5 of the switch block SW3 control the IRQ level.
|

There is a DIP-switch with 8 switches, used to set the shared memory address
|
|
to be used. The first 6 switches set the address, the 7th doesn't have any
|
|
function, and the 8th switch is used to select "compatible" or "enhanced".
|
|
When I got my two cards, one of them had this switch set to "enhanced". That
|
|
card didn't work at all, it wasn't even recognized by the driver. The other
|
|
card had this switch set to "compatible" and it behaved absolutely normally. I
|
|
guess that the switch on one of the cards, must have been changed accidentally
|
|
when the card was taken out of its former host. The question remains
|
|
unanswered, what is the purpose of the "enhanced" position?
|
|
|
|
[Avery's note: "enhanced" probably either disables shared memory (use IO
|
|
ports instead) or disables IO ports (use memory addresses instead). This
|
|
varies by the type of card involved. I fail to see how either of these
|
|
enhance anything. Send me more detailed information about this mode, or
|
|
just use "compatible" mode instead.]

[Avery's note: these don't work with my driver for some reason. These cards
|
|
SEEM to have settings similar to the PDI508Plus, which is
|
|
software-configured and doesn't work with my driver either. The "Waterloo
|
|
chip" is a boot PROM, probably designed specifically for the University of
|
|
Waterloo. If you have any further information about this card, please
|
|
e-mail me.]
|
|
|
|
The probe has not been able to detect the card on any of the J2 settings,
|
|
and I tried them again with the "Waterloo" chip removed.

|
|
hint to the existence of a manufacturer at all is written in copper,
|
|
it is "Made in Taiwan"

Setting the Node ID
|
|
-------------------
|
|
|
|
The eight switches in group SW1 are used to set the node ID.
|
|
Each node attached to the network must have an unique node ID which
|
|
must be different from 0.
|
|
Switch 8 serves as the least significant bit (LSB).
|
|
|
|
The node ID is the sum of the values of all switches set to "1"
|
|
These values are:
|
|
|
|
Switch | Value
|
|
-------|-------
|
|
8 | 1

|
|
|
|
The first three switches in switch group SW2 are used to select one
|
|
of eight possible I/O Base addresses using the following table
|
|
|
|

|
Setting the Base Memory (RAM) buffer Address
|
|
--------------------------------------------
|
|
|
|
The memory buffer requires 2K of a 16K block of RAM. The base of this
|
|
16K block can be located in any of eight positions.
|
|
Switches 4-6 of switch group SW2 select the Base of the 16K block.
|
|
Within that 16K address space, the buffer may be assigned any one of four
|
|
positions, determined by the offset, switches 7 and 8 of group SW2.

|
|
|
|
|
|
Setting Interrupt Request Lines (IRQ)
|
|
-------------------------------------
|
|
|
|
To select a hardware interrupt level set one (only one!) of the jumpers
|
|
IRQ2, IRQ3, IRQ4, IRQ5 or IRQ7. The manufacturer's default is IRQ2.
|
|
|
|
|
|
Setting the Timeouts
|
|
--------------------
|
|
|
|
The two jumpers labeled ET1 and ET2 are used to determine the timeout
|
|
parameters (response and reconfiguration time). Every node in a network
|
|
must be set to the same timeout values.
|
|
|
|
ET1 ET2 | Response Time (us) | Reconfiguration Time (ms)

NONAME 16-BIT ARCNET
|
|
====================
|
|
|
|
The manual of my 8-Bit NONAME ARCnet Card contains another description
|
|
of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
|
|
because there are missing two pages in the manual booklet. (The table
|
|
of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
|
|
the booklet there is a different way of counting ... 2-9, 2-10, A-1,
|
|
(empty page), 3-1, ..., 3-18, A-1 (again), A-2)
|
|
Also the picture of the board layout is not as good as the picture of
|
|
8-Bit card, because there isn't any letter like "SW1" written to the
|
|
picture.
|
|
Should somebody have such a board, please feel free to complete this
|
|
description or to send a mail to me!
|

|
|
Setting the Node ID
|
|
-------------------
|
|
|
|
The eight switches in group SW2 are used to set the node ID.
|
|
Each node attached to the network must have an unique node ID which
|
|
must be different from 0.
|
|
Switch 8 serves as the least significant bit (LSB).
|
|
|
|
The node ID is the sum of the values of all switches set to "1"
|
|
These values are:
|
|
|
|

Setting the Base Memory (RAM) buffer Address
|
|
--------------------------------------------
|
|
|
|
The memory buffer requires 2K of a 16K block of RAM. The base of this
|
|
16K block can be located in any of eight positions.
|
|
Switches 6-8 of switch group SW1 select the Base of the 16K block.
|
|
Within that 16K address space, the buffer may be assigned any one of four
|
|
positions, determined by the offset, switches 4 and 5 of group SW1.

|
Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not
|
|
switches.
|
|
|
|
Setting the jumpers to ON means connecting the upper two pins, off the bottom
|
|
two - or - in case of IRQ setting, connecting none of them at all.
|
|
|
|
Setting the Node ID
|
|
-------------------
|
|
|
|
The eight switches in SW2 are used to set the node ID. Each node attached
|
|
to the network must have an unique node ID which must not be 0.
|
|
Switch 1 (ID0) serves as the least significant bit (LSB).
|
|
|
|
Setting one of the switches to Off means "1", On means "0".
|
|
|
|
The node ID is the sum of the values of all switches set to "1"
|
|
These values are:
|
|
|
|
Switch | Label | Value
|
|
-------|-------|-------
|
|
1 | ID0 | 1
|
|
2 | ID1 | 2

The last three switches in switch block SW1 are used to select one
|
|
of eight possible I/O Base addresses using the following table
|
|
|
|
|
|

Setting the Base Memory (RAM) buffer Address
|
|
--------------------------------------------
|
|
|
|
The memory buffer (RAM) requires 2K. The base of this buffer can be
|
|
located in any of eight positions. The address of the Boot Prom is
|
|
memory base + 0x2000.
|
|
Jumpers 3-5 of jumper block SW1 select the Memory Base address.
|
|
|
|

|
|
ON ON OFF OFF OFF | E0000 | E2000
|
|
|
|
*) To enable the Boot ROM set the jumper 8 of jumper block SW3 to position ON.
|
|
|
|
The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM adders.
|
|
|
|
Setting the Interrupt Line
|
|
--------------------------
|
|
|
|
Jumpers 1-5 of the jumper block SW3 control the IRQ level.
|
|

|
|
------------------------------
|
|
|
|
The jumpers 6-7 of the jumper block SW3 are used to determine the timeout
|
|

SW1: Timeouts, Interrupt and ROM
|
|
---------------------------------
|
|
|
|
To select a hardware interrupt level set one (only one!) of the dip switches
|
|
up (on) SW1...(switches 1-5)
|
|
IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
|
|
|
|
The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
|
|
are used to determine the timeout parameters. These two dip switches
|
|
are normally left off (down).
|
|
|
|
To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM.
|
|
The default is jumper ROM not installed.
|
|
|
|
|
|
Setting the I/O Base Address
|
|
----------------------------
|
|
|
|
The last three switches in switch group SW2 are used to select one
|
|
of eight possible I/O Base addresses using the following table
|
|
|
|
|
|
Switch | Hex I/O
|
|
4 5 6 | Address
|
|
-------|--------
|
|
0 0 0 | 260
|
|
0 0 1 | 290
|
|
0 1 0 | 2E0 (Manufacturer's default)
|
|
0 1 1 | 2F0
|
|
1 0 0 | 300
|
|
1 0 1 | 350
|
|
1 1 0 | 380
|
|
1 1 1 | 3E0
|
|
|
|
|
|
Setting the Base Memory Address (RAM & ROM)
|
|
-------------------------------------------
|
|
|
|
The memory buffer requires 2K of a 16K block of RAM. The base of this
|
|
16K block can be located in any of eight positions.
|
|
Switches 1-3 of switch group SW2 select the Base of the 16K block.
|
|
(0 = DOWN, 1 = UP)
|
|
I could, however, only verify two settings...
|
|
|
|
Switch| Hex RAM | Hex ROM
|
|
1 2 3 | Address | Address
|
|
------|---------|-----------
|
|
0 0 0 | E0000 | E2000
|
|
0 0 1 | D0000 | D2000 (Manufacturer's default)
|
|
0 1 0 | ????? | ?????
|
|
0 1 1 | ????? | ?????
|
|
1 0 0 | ????? | ?????
|
|
1 0 1 | ????? | ?????
|
|
1 1 0 | ????? | ?????
|
|
1 1 1 | ????? | ?????
|
|
|
|
|
|
Setting the Node ID
|
|
-------------------
|
|
|
|
The eight switches in group SW3 are used to set the node ID.
|
|
Each node attached to the network must have an unique node ID which
|
|
must be different from 0.
|
|
Switch 1 serves as the least significant bit (LSB).
|
|
switches in the DOWN position are OFF (0) and in the UP position are ON (1)
|
|
|
|
The node ID is the sum of the values of all switches set to "1"
|
|
These values are:
|
|
Switch | Value
|
|
-------|-------
|
|
1 | 1
|
|
2 | 2
|
|
3 | 4
|
|
4 | 8
|
|
5 | 16
|
|
6 | 32
|
|
7 | 64
|
|
8 | 128
|
|
|
|
Some Examples:
|
|
|
|
Switch# | Hex | Decimal
|
|
8 7 6 5 4 3 2 1 | Node ID | Node ID
|
|
