[coreboot] Device number to use with testbios & lspci output difference between Commercial BIOS and coreboot

[Ken.Fuchs at bench.com]

I have a PCI video card in an nVidia CRB system that I'm
trying to init via testbios (user mode VGA option ROM init).

I need to determine which device number (-d argument)
I should use with testbios, so I did a lspci under
coreboot, but the video card doesn't seem to show up.

When I switch back to the Commercial BIOS, the video
card is clearly identified as:

01:06.0 VGA compatible controller: Tseng Labs Inc ET6000 (rev 30)

lspci output for both LinuxBIOS and Phoenix BIOS appears
after my sig.

The testbios command line I'm using is:

./testbios -s 65536 --abseg /dev/mem ./vgabios1.bin

What should the -d argument for testbios be?

It is confusing that LinuxBIOS (coreboot) and Phoenix BIOS
are using different PCI bus numbers.  I always assumed
that didn't matter, but now I'm not so positive.  Does
it really matter?

Sincerely,

Ken Fuchs
