Mine were both on IRQ 11 also. Can't remember how it happened but the SIS
NIC moved to IRQ 10. Possibly it happened when I disabled Plug n Play OS in
the BIOS... or removed it in Device Manager and on reboot it settled into
the spare IRQ. Anyhow, it can be done.

Sometimes the order in which windows has detected devices can affect
the IRQ assignment.Try this.
Boot to Safemode/Device Manager and remove,"All" entries for the video
card and re-boot and let windows re-install them and check the IRQs.If
this doesn't work do the same for the NIC.
HTH :)

there is one option that might be available to you, first you will
have to flash the Honeyx BIOS, then change the puter type to "ACPI
uniprocessor HAL" in device manager, then on reboot, enter BIOS setup
and enable the I/O APIC in the CPU page and all your devices will get
their own IRQ on reboot. Worked with my system. One word of warning,
if the CMOS is reset, you MUST re-enable the I/O APIC for win2k/XP to
boot properly due to the new IRQ assignments.
Search google groups for "APIC K7s5a" and you should find some posts
on this.

Win9X/ME doesn't support APIC but it's no biggy.What happened started
when PCI IRQ Bus Master sharing was introduced in win95B.It allowed
devices to share IRQs but only if the hardware maker's adhered to MS
regulations/code for it.Some refused and some were just plain crap at
coding the BIOS of their devices.Then MS made the IRQ sharing more
efficient by bringing in USB around or just after the IRQ sharing so
some standard devices could be loaded through USB which is designed to
share IRQs.
Over the years I've built and tested all sorts of configs and I've
deliberately had things like sound cards in PCI slot 1 so it will
share with the AGP card and with a good device there was no problem.I
like to keep the AGP card on it's own IRQ more out of habit and the
fact windows has a way of screwing them up from time to time but if
there's no apparent problem then just enjoy the fact the O/S and the
hardware are actually doing what they are supposed to do.
Many sound card makers set their cards to share with a parallel
printer port in the knowledge that the printer most likely won't be
used that often anyway or not usually for sustained periods thus the
IRQ/Bus won't get clogged.If you don't use a parallel printer then
save an IRQ and disable it in the BIOS.Do the same for the External
com ports if you don't use any serial devices and the go back to
Safemode and remove the video card or the NIC again and you never know
:)
If it's really bugging you and you don't mind losing the ACPI
Advanced Power Management functions(and they ain't all that anyway)
then use the method on here to remove ACPI,

and you can then also manually assign the IRQs from the Device
Mangler<sic> if windows doesn't do a good job.
