You wrote earlier that 12.4 is invisible under factory. If you enable the bios option mentioned above, is it still invisible? Do you see any difference if you use lspci -vvvxxx ?
Yes, device 00:12.4 is not shown in both cases, it is totally ignored. There is nothing about that. Same with cat /proc/pci no 12.4 (or 18.4) under factory bios.
I had a look with "modbin" to the factory bios. There is a hidden field called "multiple monitor support". I know that option from other boards. You can choosen "no Onboard" "PCI first" and "Both" if I remember right. As I say this is disabled and therefor not shown in Bios setup. Both "Bios defaults" and "setup defaults" are set to "no Onboard"
I think this disables normaly the "real onboard" vga. As I say, the 00:9.0 device is more like a integrated pci card on board.
I should also say, that this mobo has no real pci slots, there is an expansion slot where you can put in a riser card (ISA/PCI Riser card). But it should be the same as a pci bus.
I'm not sure, but why are there differences between lspci and cat /proc/pci . I get other device numbers with cat
device 12 is 18 device 13 is 19
is that normal? the functions are the same
