i am trying to get a megaraid controller working on my redhat 8.0 linux box. i have put the card in. when i boot the operating system sees the card but i cant get to the drives attached to it. i looked in my dmesg file and found the following:

megaraid: v1.18d (Release Date: Wed Aug 7 18:51:51 EDT 2002)
PCI: No IRQ known for interrupt pin A of device 04:01.0. Please try using pci=biosirq.
megaraid: found 0x101e:0x1960:idx 0:bus 4:slot 1:func 0
scsi2 : Found a MegaRAID controller at 0xf885a000, IRQ: 0
scsi2 : Enabling 64 bit support
megaraid: Couldn't register IRQ 0!
Trying to free nonexistent resource <f885a000-f885a00f>
megaraid: no BIOS enabled.

does anybody know how i can set this device to look at a different IRQ? and also how to enable the BIOS on it?

thanks for you help
