Dell PRECISION 530 - Manual (Page 77)

• After installing a SCSI hard drive, Primary Drive 0 and Primary Drive
1 should be set to None in system setup if no EIDE hard drives are
installed. If you have any EIDE devices on the second EIDE channel,
such as a CD or tape drive, Secondary Drive 0 and/or Secondary Drive
1 should be set to Auto.
• You may need to use programs other than those provided with the
operating system to partition and format SCSI hard drives. Refer to
the documentation that came with your SCSI software drivers for
information on installing the appropriate drivers and preparing your
SCSI hard drive for use.
SCSI Cables
Ultra 160/m and Ultra2/Wide LVD drives (typically hard drives) both use a
68-pin cable. One end of the cable attaches to the SCSI connector on the
system board or the SCSI controller card installed in your computer. The
remaining connectors on the cable attach to the various drives.
Narrow SCSI drives (optional SCSI cards such as tape drives, CD drives,
and some hard drives) use a 50-pin cable. One end of this cable attaches to
the SCSI controller card. The remaining connectors on the cable attach to
the various Narrow SCSI devices.
NOTICE: Dell recommends that you use only SCSI cables purchased from
Dell. Cables purchased elsewhere are not guaranteed to work with Dell
computers.
