RE: IRQ Conflict

Do you want to run both video cards?  If not, simply disable the video
card in the BIOS.  While you're there, turn off the plug n play
operating system.  I don't think that'll be a problem, unless you go
sticking new hardware in and are still running ms stuff.

Good luck,

Al

I have two video cards: one integrated Intel i810 and one ATI Rage 128
Pro PCI.  They're both on IRQ 10.  Whenever I run Xconfigurator, it
properly detects the ATI card and monitor, but doesn't work when testing
the settings.

Returns error "No Screens Detected."

If it's not IRQ, what is it?

Joseph - I have a rather sketchy knowledge of these matters, but as I
understand it, the PCI bus is designed so the computer can manage more
devices than it has IRQs.  Through some software magic, devices with the
same IRQ are able to work together on the PCI bus.  Windows does not
like this, so it pretends to assign different IRQs to the different
devices.  If you check the initial settings listed while the computer is
booting up, you'll probably see that the CMOS agrees with Linux.  If you
are having difficulty getting the two devices to work together, you
might try to find a reason besides IRQs.   -Glenn.

I have an IRQ conflict between two PCI devices.
