Problems Booting the System from a SCSI Drive

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

Make sure that the SCSI boot drive address is set to SCSI ID 0:0. Check the drive installation manual for informa- tion about 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.

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

Verify the proper installation and configuration of the host adapter and SCSI devices.

Power should be cycled OFF and ON after changing any values on a host adapter, setup program, or SCSI device, to be sure that a DOS format operation has been success- fully completed.

Make sure that the SCSI bus is properly terminated.

Make sure that the intended boot disk has an active DOS partition and a DOS format.

Check the cabling.

Problems Using a SCSI and a Standard Disk Drive

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

Make sure that the second standard fixed disk is mapped out of the system.
