1. patch chip bugs<BR>
2. installed BIOS call, so OS can boot from SCSI...<BR>
3. PXE boot from network...<BR>
4. Some UO for setup.<BR>
5. VGA card, init ....<BR>

So depend what card that you are going to use.<BR>

Subject: [LinuxBIOS] PCI Express add-on cards and Expansion Roms<BR>
<BR>
Hello All,<BR>
<BR>
<BR>
<BR>
I am trying to work on getting a PCI-E card working and came across an error that I am wondering if I need to worry about. Below shows that the VGA ROM is loading, but not the ROM from the PCI-E card (at the bottom). Both of these cards are in slots and not onboard. The PCI-E card is an Ethernet card. As the device is getting a bus and resources seemingly just fine, I would think that the ROM would have been found. My question is ... do all add-on cards need to load an expansion ROM or can they run just fine without it? The error in question is "Incorrect Expansion ROM Header Signature ffff".<BR>
