I wrote the code, and can assure you that the BIOS in the message
is referring to the ROM BIOS.

Nope.

Nope. It refers to the PCI BIOS specification implemented.

>The reason your AMI BIOS version and AHA version isn't reported is simply once
>the linux kernel is booted it doesn't use BIOS,

Nope. Certain 32-bit interfaces, such as that provided by the PCI BIOS,
are used after bootup. The PCI BIOS code is used for probing and a few
post-mortem checks.

>(note there is a section of
>the kernel that is called BIOS, but it doesn't use any of the computer's bios).
Nope.
