[LinuxBIOS] How to enable VGA on Tyan S3992?

[Feng, Libo]

I changed the mainboard Config.lb according to the below suggestion. It still can't work.
  
PCI: 00:0c.0 init
rom address for PCI: 00:0c.0 = fc220000
Incorrect Expansion ROM Header Signature 7070 

The address is always wrong. However, from the boot log, elfboot seems find something at 0xfffc0000.

BTW, I always run buildtarget after changing Config.lb, is it OK?

Best Regards
