Hi all,

Recently I installed kernel 2.4.0 (nice job!) on a Compaq Deskpro 4000 with
a Pentium 133 Mhz processor. It seems to run fine, but during boot
I get the following message:

PCI: No IRQ known for interrupt pin A of device 00:0f.1. Please try using
pci=biosirq.

If I try that it still gives the error, except for the "Please try using
pci=biosirq" part.

What can cause this, and is there a solution for it?

Thanks in advance,

Gerard
