Problems Using Two SCSI Drives

EISA-to-Fast SCSI Host Adapter

Troubleshooting

Make sure that the SCSI drive to be used as drive D is set to SCSI ID 0:0. Check the drive manual for information on setting the SCSI ID for that device. The Return In- stalled Devices utility in the Onboard utilities can also be used to determine the SCSI addresses of peripherals on the SCSI bus.

Make sure that SCSI parity is consistently enabled or dis- abled on all devices on the SCSI bus.

Verify that the host adapter and the SCSI devices are properly configured and installed.

Power should be cycled OFF and ON after changing any values on a host adapter, setup program, or SCSI device to be sure that the new initial values are loaded.

Make sure that the SCSI bus is properly terminated.

Make sure that the disk has a DOS partition and a DOS format.

Check the cabling.

Problems Using Two SCSI Drives

The drives are configured as SCSI disk drive D and SCSI disk drive C.

Make sure that both standard fixed disks are mapped out of the system with the setup program.

Make sure that the SCSI drive to be used as drive D is set to SCSI ID 0:1 or 1:0. Check the drive manual for infor- mation on setting the SCSI ID for that device. The Return Installed Devices utility in the Onboard utilities can also be used to determine the SCSI addresses of pe- ripherals on the SCSI bus.
