Hi

Could be that we have to enable access to the ROM first. That's why 
it returns only 0xffff. Does the card display output when you switch 
on the computer?

Hello Thomas,

No, the card doesn’t display output when I switch on the computer.

Attached you'll find another patch that also enables ROM access in the 
PCI config options.  I took the code out of the old matroxfb driver 
without further testing. Please try and report back on the results.

Best regards
Thomas

Hello Thomas,

Thank you for your effort to solve the problem. Unfortunately, your new 
patch doesn't solve the problem either. The error outputs are the same 
as before.

Cheers,
Christian
