YO Drill,
It sounds like you've got the sb dos drivers loaded, or trying to load.
SB emulation needs to be using irq5. But it seems that another device is using it. At least that's what I take from what you posted.
You can check the IRQ's in system>device manager>properties
If sb emu is not on Irq5 then what u need to do is move the card to another slot. That usually changes IRQ. When I build a sys I skip pci slot 1 put sb in slot 2, skip slot 3 another device in slot 4, etc..
Also when You install the sb drivers use custom and uncheck dos drivers, and demo stuff.
