How to set the IRQ on a Compaq?

[Rob Judd]

I have installed a Netgear FA 310 TX in a Compaq presario 4640 running
Linux 2.0.36, but I cannot get it to run.  The IRQ shows up as 255, while
W95 gives it IRQ 9.  I read
http://cesdis.gsfc.nasa.gov/linux/misc/irq-conflict.html
which says, in particular:

"If the card is reporting IRQ0 or IRQ255, that indicates the card has not
been assigned an interrupt. There are two likely fixes: either the BIOS
does not have enough IRQ lines available for PCI devices (e.g. all are
assigned to "legacy" ISA devices instead of "PnP"), or the BIOS has a "PnP
OS" setting that must be disabled."

I have no idea how to disable the BIOS PnP OS setting, if that is the
problem here.  There are slots for two ISA and two PCI cards - the only
one in use is the ethernet card.

Can anyone help me with this, please?  Is there a way to assign the IRQ
inside the driver?

Any help would be much appreciated.

TIA
