Cards don't select their IRQs any more, Ken, your BIOS or OS - or yourself,
in some cases - will do that. I saw your earlier thread; afraid I don't use
W2K or your board, so I have no idea what to suggest. However, getting
another card is unlikely to change the assigned IRQ. The only things I
might suggest if you can't change it specifically in the BIOS or OS are a)
the time honoured solution of changing your other cards around, to see if
the IRQ reshuffle also reassigns your AGP card IRQ and b) if you have Assign
an IRQ to VGA enabled in your BIOS (which it should be), disable it, reboot,
let the OS do its bit, then go back and reenable it - again, the reshuffle
might assign it a different IRQ.
The days are long gone when you selected the IRQ on a non P&P card with
jumpers...

Well, I FINALLY resorted to looking in the mb manual and found that the
AGP slot shares the same IRQ as the USB host controller HC0 (HC1 and
HC2 use different interrupts). I also tried the Iomega USB external
hard drive on my wife's computer, which also has a similar sharing of
IRQ16 with the video card and HC0, and it works. So I am baffled.
Clearly, the problem does not lie with the video card, and I am not
sure that it is an issue with the host controller. I have tried the
Iomega site and all the fixes that they have for a non-recognized drive
in Win2K do not work....
Oh, well, thanks for your help.

In Win2K and XP, IRQs are assigned by the OS and shared. Thus Graphics,
Sound, NIC and USB on 1 IRQ.
To go back to separate IRQs you need to disable ACPI
power management.Disable ACPI in Mobo Bios then reinstall the OS and press
one of the F keys during the install to change from ACPI to Standard PC. Do
a search on Microsoft on IRQ sharing and you should find more info. Also you
should disable redundant Hardware in the Mobo Bios - Parallel port and
Serial Ports that aren't being used.

Only thing I can think of in that case, Ken, if you have enough USB sockets
to be going on with, anyway, is to disable your HC0 controller, if that's
possible to do without disabling the other controllers. Sounds like it's
not going to be possible to separate the IRQs. I must admit, I'm a long way
from being a mobo designer, but that's not how I would design one!
