Linda,
If your computer is "PCI 2.1 Compliant" and your various cards are also 2.1
Compliant, devices can share IRQ's. I had three video cards working on IRQ 9
for a couple of months. It wasn't perfect, but it worked (the cards blew
up). My new setup has a video card and 100mb network card on the same IRQ
and it floats along great.
That standard was established by Intel a while back. The computer is
question has to be newer than "slot 2" design (if I remember correctly)
which goes back to Pentium 60's to 75's. Anything newer probably complies.
Look carefully on the specs of any new device and it will likely address the
compliance.
Hope this helps,
Mark
P.S. Sorry, this is a little off 'Trading', but it seems us traders have to
try to be computer geeks also.

Len, I see that all 15 of my IRQs are committed on my Sony 450, but I also
see that some are used by more than one device. How do I know if others are
available to be shared?
