2.  Be sure the SCSI drive to be used as drive C is set to SCSI ID 0 (AHA-2940/2940W Adapters). See 'SCSI Disk Utility'
3.  Set the SCSI drive to be used as drive D to SCSI ID 1.
4.  Try enabling Include in BIOS Scan in the SCSI Device Configuration option of the SCSISelect  utility. See 'SCSI Device Configuration'
5.  Be sure to power-off, the power-on the computer after changing any values on the host adapter, in Setup, or on a SCSI device.
6.  Be sure that SCSI parity is consistently enabled or disabled on the SCSI bus.
7.  Verify that the host adapter and the SCSI devices are properly configured and installed.
8.  Be sure the SCSI bus is properly terminated.
9.  Be sure the disk is formatted and has a DOS partition. Run the Format Disk utility accessible through SCSISelect . See 'SCSI Disk Utility'
