Hard Disk Drive Jumper Settings
Up to four drive devices (hard disk, CD/DVD-ROM, or Zip drives) can be
installed in Service Level A systems. If any drives do not show in the
Installed Devices list in the Setup Utility, ensure the jumper settings and
connectors are set as shown here. Refer to “System Board Layout—Type
A-1” on page 5-2 and “System Board Layout—Type A-2” on page 5-5 for
connector location information.
Primary Hard Disk Drive IDE Local Bus Connector
At the primary hard disk drive IDE connector, make sure the first drive
installed is set as the master drive ( 1 in the following figures).
Note: If a second drive is installed, it must be attached to the secondary
IDE connector. Set the jumpers as the slave drive ( 2 in the
following figures).
All recovery preloaded software should be installed on the master hard disk
drive on the primary connector.
Secondary Hard Disk Drive Connector
If additional drives are connected to the secondary hard disk drive
connector, set the first drive connected to this connector as the master drive
( 1 in the following figures). If a second drive is connected to the
secondary hard disk drive connector, set the jumpers as the slave drive ( 2
in the following figures). Ensure all software is set to recognize all installed
drives. If an additional hard disk drive is connected to the secondary
connector, it must be set as the master drive, 1 , and the CD/DVD-ROM
drive jumpers reset as the slave drive (see “CD/DVD-ROM Drive Jumper
Settings” on page 5-13).
Note: Check the Setup Utility for correct installation:
Hard Disk 1 Master drive
Hard Disk 2 Slave drive
Hard Disk 3 Master drive (CD/DVD-ROM if other drive not connected to
this connector. Also, Zip drive with internal Zip drive
models)
Hard Disk 4 Slave drive (CD/DVD-ROM if hard disk or internal Zip drive
installed at secondary connector, Hard Disk 3)
