Re: [CentOS] Tyan S2891 and CentOS -- 6, 8, 10+ PCI busses in today's new systems

Secondly, try booting with a combination of ACPI/PCI kernel parameters. Using "pci=bios" might solve the problem, especially if you have the latest BIOS.

Thanks for the hints on using pci=. I got it to work. I couldn't find where pci=bios was documented but that option didn't work. I read in the kernel docs in regards to booting and tried pci=conf1 and this worked. The machine is up and running and doing well under testing. I don't know what conf1 means but I be darned if it doesn't work :)

If you hit the archives regarding the Tyan S2895 (Thunder K8WE), you'll find the boot-time option that person used (I believe it was "pci=bios"?).

Do you know where this option is documented?
