I have been fighting with my Diamond Supra Max PCI win modem. Whenever I install it, it steals IRQ 5 away from my Sound Blaster 64 ISA. All other available IRQs are used except for the comm ports. No devices are attached to them. Device manager shows com 3 & 4 installed. The resource tab in modem properties WILL NOT let me moify the IRQ to 3.(the modem is installed on com3)The same goes when I install on com 4, it won't let me change the IRQ. Is there any other way I can fix this?
Strangly enough, before I had a GVC modem in, my video card did not show in device manager(IRQ 10)and that is what my ISA sound card used.
