Re: what is pci=biosirq

[Don Dugger <n0ano@valinux.com>]

The error message idicates that the MPS table doesn't provide interrupt
routing information for that PCI slot.  I ran into the same problem
on my K6 machine.  I was able to fix it in the BIOS.  In the BIOS setup
go to the `Advaned' page.  Look under `Installed O/S'.  It probably
says something silly like `Win95' or `Win98/Win2000'.  Change it to
`Other' and your problem should go away.
