But you can read out the original ROM file? If you switch to FWH
(49lf008a) you will need to set FakeAsrEn [PM_Reg:8Fh] UseBypassRom[1]
and BypassRomSel[3:2].

You can check the range :
LPC ROM Address Range 2 (Start Address)- RW - 16 bits - [PCI_Reg: 6Ch]
LPC ROM Address Range 2 (End Address) - RW - 16 bits - [PCI_Reg: 6Eh]
It should be 0xfffffff0 meaning 0xfff00000-0xffffffff

Rom Protect 0 - RW - 32 bits - [PCI_Reg: 50h]
Should be 0.

That is all I can think of at the moment.
