>> It only accepts IRQ 2 3 4 or 5. I have all of these in use. The 'lack of available INTerrupts' problem can be solved by stealing one from the high half of the bus. One method I have used in the past is to solder a wire to an unused high-side INT pin on a neighboring board and bring the wire across to the INT jumper on the 8-bit card. Another option is to find an unused 16-bit board (junk pile of local surplus house?) and cut off the high-half fingers with enough room for attaching wires. Plug this in the same slot as the 8-bit card and jumper as above. I once found some nice edge-card plugs that fit right into the C/D slot, with single level .025 posts to accept jumpers, this made for a solution that the hardware guys didn't even laugh at... You might have to hack some code, oftentimes a driver won't accept the fact that it can use a high-side INTerrupt. With any of these methods, be CAREFULL, a short can destroy a motherboard! Don't attempt unless you are comfortable with the idea.
