Some of them don't have correct 0x55aa signature. All of them have
wrong Class code.
Then it is not a pci option rom as described by the standard. Do they
have the other pci option rom structs?

It is weird that fuctory bios can still use them.
There's gotta be a hack in fuctory bios, I would guess, something like:
if (the pci card is a vga there is an option rom)
callit();
i.e. I betcha that fuctory bioses will call an option rom on vga even if
it violates the spec.

I doubt that.. I've scrubbed the 0xAA55 from several VGA cards so I
could plug them into a factory bios system and not have the VGA
enabled. None of them ever went ahead and ran the bios.

Before that any data may occur. IIRC the standard does not say that the
option rom image has to start at the beginning of the physical chip.
I never saw that requirement

Ollie,
I recall sth about mtrr setting, I wonder if I enable the NC could affect
your code. Please check cpu/x86/mtrr/mtrr.c about enable NC below 4G.

I think there is some problem with the resource allocation. If the vga

As the Nvidia card it does
not have PCI IO resource so we got the 2 to 1 thing.
It mean it doesn't allocate resource to it. Limitstart
But why it set the resource to the HW registers? Doesn't it cause
some ill side effect?

I am still debugging PCI cards. Once I have PCI cards working
I will disable these messages.

Ollie, you did it!
Ollie just took a big stack of video cards, some AGP and some PCI, and
booted linuxbios one at a time and showed how each video card came up.
It's fantastic.
now, Stefan, time for openbios payload. Then we have a desktop PC that
prints an Open Boot prompt :-)
