Introduction
|
|
------------
|
|
|
|
This plugin allows updating ATA/ATAPI storage hardware. Devices are enumerated
|
|
from the block devices and if ID_ATA_DOWNLOAD_MICROCODE is supported they can
|
|
be updated with appropriate firmware file.
|
|
|
|
Updating ATA devices is more dangerous than other hardware such as DFU or NVMe
|
|
and should be tested carefully with the help of the drive vendor.
|
|
|
|
The device GUID is read from the trimmed model string.
|
|
|
|
Firmware Format
|
|
---------------
|
|
|
|
The daemon will decompress the cabinet archive and extract a firmware blob in
|
|
an unspecified binary file format.
|
|
|
|
This plugin supports the following protocol ID:
|
|
|
|
* org.t13.ata
|
|
|
|
GUID Generation
|
|
---------------
|
|
|
|
These device use the Microsoft DeviceInstanceId values, e.g.
|
|
|
|
* `IDE\VENDOR[40]REVISION[8]`
|
|
* `IDE\0VENDOR[40]`
|
|
|
|

|
