First, I don't understand why OS/2 also assigns IRQ 15 to the sound card since IRQ 14 and 15 are reserved for the Primary and Secondary IDE channel resp. IRQ 3,4 and 5 can be used by either the serial port (internal and external) or ISA cards (check BIOS). Using them for PCI should only be done when there is NO ISA card in ANY slot. Keep them legacy otherwise and you have enough IRQ's > 8 to accomodate all extension cards. But on the other hand, only use IRQ sharing between non-sound card cards.

There is one thing that DOS is perfect for on old hardware : using the setup floppy that should have come with your card. Usually there is a small port setup and test utility with which you can figure out the IRQ/IO combo or it tells you if the card needs jumpers set. There should be a leaflet explaining on how to turn also the card from automatic (f.i. through PNP) to manual setup. Concerning PS/2, it usually is routed to IRQ 12 (check your BIOS, sometimes it gives you the option of freeing IRQ 12 up for regular PCI usage). > ISA. Phooey! All I said is pretty general. In order to help, can you give me : ANY current BIOS setting related to IRQ's/IO ports and, if supported, binding to INT#'s, occupied serial ports, all extension cards (including order in slots) including assigned IRQ's after boot. Also, if you happen to have info on which card (ISA and PCI) have manual setting jumpers... Guy
