So I have an Asus P3B-F with two ISA slots. I decided to get a GUS card, and seat it next to my beloved AWE64 recently. The board allows me to move one of the serial ports to IRQ10 from either IRQ3 or 4 and I thought I could use it such that my IRQ7 can be left as-is with the parallel port (which I'm planning to dust off my ZIP drive for). However the Iwavecfg program does not allow me to set the card's IRQ to 3.

Is there any way I can force the card to IRQ3? Or am I stuck and there is no other way but to turn off the parallel port?

Also, I'm having issues getting both cards to co-exist in Windows 3.1. Since installing the GUS the Creative Mixer in Windows appear to have become broken and can't be used to adjust the volume controls of the AWE64. Aside from that both cards coexist in DOS fine.
