STATUS_ABIOS_INVALID_COMMAND

ABIOS request blocks carry a function as well as the device Logical ID

IBM documents the ABIOS request block as a common set of functional parameters followed by service-specific parameters. The common fields include request-block length, Logical ID, unit, function, return code, and timeout. STATUS_ABIOS_INVALID_COMMAND is therefore best diagnosed by preserving the function field and the LID/device context that interpreted it. A command can be meaningful in one firmware service and invalid in another.

This is different from STATUS_ABIOS_INVALID_LID. A malformed or unsupported function targets the command side of the request contract; changing the LID without understanding the request may simply send the same invalid function to a different device. Likewise, a valid function number is not sufficient if the request-block length or service-specific parameters belong to a different ABIOS interface revision. The public NTSTATUS catalog does not expose a table of Windows-specific ABIOS command numbers, so decode the function against the firmware documentation for the actual device/service.

For historical driver analysis, capture the entire request block before firmware dispatch, not just the return status. Compare function, unit, block length, and any service-specific fields with the function-transfer table and device block associated with the current LID. If the failure follows a machine or emulator change, compare supported ABIOS services rather than assuming the old function set is universal across PS/2 models.

What to inspect

Save the full ABIOS request block, especially LID, unit, function, and length.
Decode the function against the addressed device/service documentation.
Check interface revision or emulator changes before treating the status as hardware failure.
