I tried changing some of these at one time but it did not seem to have any effect. I must be missing something here. The printed manual says that slots 2 and 5 share an IRQ. I have the NetGear NIC in slot 2 and slot five is empty. > You did not mention which OS you were using but Win95 would let you reassign > resources through "Device Manager" on some cards.

I looked for this option in the BIOS and in the manual but cannot find anything about disabling the PS/2 mouse port. I may change to a PS/2 mouse to free up an IRQ - I need one for the USB ports. > > The manual says that this motherboard comes with on board sound, did you > disable the "Onboard Sound chip" option in the BIOS?

There are no sound options available in the BIOS and the manual has an addendum that says that none of the sound options applies to this motherboard.
