I have something here in the office that will assert the SCSI reset line and never release it if you do an inquiry before the device is fully initialized. This freezes up the 1542 during boot. This device has an embedded PC in it and it is the power up firmware in the host adapter that loses so badly, making it a little forgiveable on the device vendor's part. -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc.
