I have an nVidia CRB system that generates
difference lspci output depending on whether the Commercial
BIOS or LinuxBIOS (coreboot) is used.
--- Summary of lspci output differences ---
When using LinuxBIOS (coreboot), the PCI video card doesn't
appear. When I using the Commercial BIOS, the video card is
clearly identified as:
01:06.0 VGA compatible controller: Tseng Labs Inc ET6000 (rev 30)
The Comm. BIOS 00:18-19.x remains LinuxBIOS 00:18-19.x.
The Comm. BIOS 00:00-0e.x becomes LinuxBIOS 01:00-0e.x,
with some device # changes and one function # change.
The Comm. BIOS 80:00-0e.x becomes LinuxBIOS 02:00-0e.x,
but LinuxBIOS has the following additional entries:
in MB Options.lb
#HT Unit ID offset, default is 1, the typical one, 0 mean only one HT device
#real SB Unit ID, default is 0x20, mean dont touch it at last
#make the SB HT chain on bus 0, default is not (0)
#only offset for SB chain?, default is yes(1)
but second HT still on bus 0x40...
