Due to itĞs "The User would never need to know about that" design, it is absolutely *not* possible to move a mouse IRQ. Either it connects to a stock-standard COM1 (IĞm not sure, it *might* find one on COM2) or it uses a PS/2 mouse on IRQ12. Actually, since COM1 has a lower IRQ priority than COM2, you should by preference put the mouse on COM1 and modem on COM2. Or the modem on IRQ10 which has the *highest* priority. -- Cheers, Paul B.
