IRQ Conflicts

[Walt]

When I installed two plug and play boards, a 2-serial& 1
parallel port adaptor and a USB 2.0 5-port card, they
installed with the same IRQs as existing hardware. The
Serial/Parallel card used the same IRQ as the ethernet
port and the USB card used the same IRQ as the video
card. The result was the same, video was not affected,
but the ethernet card non longer functioned properly. My
DSL service could see the port, but no communications take
place. When I removed the serial card and uninstalled the
drivers, the network performance did not improve. It was
not until I uninstalled the USB card also that the network
performance goes back to normal. If I install only the
USB card, it still uses the same IRQ as the video
adaptor. I would rather have the USB card working and use
a port replicator to get the extra serial port, if I can't
do both. HELP!!

Walt did you try a different PCI slot if available? Can you assign IRQ's
in the Bios?
