This uses IRQ 12, which would explain why your system hangs. I ordered the same SCSI card for my new machine, but the PC hasn't been delivered yet, so I could not try. I changed the IRQ of the BT driver to 11 anyway - the machine does have a PS/2 mouse port. A suggestion to the core team: change the default IRQ for the BT driver to 11. Don't use a device at IRQ 12 at all. More and more PCs come with these SMC all in one peripheral chips on board, so they have PS/2 mice. And it is very unlikely that someone will install an AH1540 and a BT adaptor in the same machine, so why not configure all SCSI cards at IRQ 11? Paddy -- Patrick M.
