Hello:

I am attempting to use an Adaptec AHA-2940UW SCSI host adapter and a 3Com
905B 10/100 ethernet adapter on a box with an older motherboard that refuses
to assign separate IRQs to PCI expansion cards.  The motherboard is a circa
1996 FIC PA-2002, rev 1.21 that I won in raffle; it came with an AMD K5-100
installed.  The PCI bud is supposed to allow more than one device to use an
IRQ but, still, such a condition can cause problems (on older hardware).

Donald Becker wrote the 3Com driver.  His webpage "Resolving Linux PCI
Interrupt Conflicts" webpage at
<http://cesdis.gsfc.nasa.gov/linux/misc/irq-conflict.html> has this to say:

". . . If the card is reporting a valid IRQ, but that IRQ is being used by
another device you have an interrupt conflict. The easiest and generally
best solution is to put the conflicting device on another IRQ line. This can
only be done through the PCI BIOS setup. Unlike ISA cards, PCI cards have no
way of setting their own IRQ. That is done at boot time by the PCI BIOS, and
the BIOS reports its selection. . . ."

Anyone solved something like this before?  I am running SuSE 5.2, kernel
2.0.33.
