IRQ conflicts w/ PCI hardware

Hi,
If this is not the proper forum for this post, please let me know and
suggest the proper group.

I have a PC with 1 ISA slot on the MB. The rest are PCI.
I have a PCI nic, and modem, and the PCI sound card is built-into the MB.

I need to turn PnP OS *off* in BIOS before installing FreeBSD, which is not
a PnP aware OS.

It turns out that all 3 of the devices listed above are using IRQ 9,
therefore only the first one detected at boot is installed. Consequently,
I have had to remove the modem to allow my nic to be detected, and since I
can't remove the sound card, I have no sound.

The only options in BIOS are to reserve an IRQ for a *Legacy ISA device*.

Is there a way to reserve IRQ's for PCI devices?

Depends on the motherboard. What motherboard is it?
