Factory-Installed Drive Devices
Use this check procedure to test any factory-installed drives.
Attention: The customer may have customized settings in the Setup Utility
(other than default settings) on the computer you are servicing. Running the
Setup Utility might alter those settings. Note the current settings and verify
that the customer settings are in place when service is complete.
Note: If you cannot access the hard disk drive or load a diskette from drive
A or load a CD from the CD-ROM drive, make sure the Setup Utility
has the startup sequence set with
Diskette
,
CD-ROM
, and
Hard Disk
enabled.
Insert the Diagnostics and Utilities CD in the CD-ROM drive. Refer to Step
006 on page 2-43 to check Hardware Configuration.
If the number of diskette drives shown in the Installed Devices list is
not correct:
1. Check the installation of the drive ribbon cable to the system board.
2. Check the voltages to the diskette drive with the power on (see “Power
Supply” on page 2-35).
3. Try to correct the drive setting in the (SETUP) option in the Setup Utility.
4. Run the “Diagnostics and Utilities Device Presence Test” on page 2-43.
If you can correct the Installed Devices list, but cannot complete the
Diagnostics and Utilities test for that device, replace FRUs, in the following
order, until the problem goes away:
1. Diskette drive cable (if continuity check fails)
2. Diskette drive
3. System board
If the number of hard disk drives, CD-ROM, or Zip drives shown in the
Installed Devices list is not correct:
1. Check the installation of the drive ribbon cable to the system board. Be
sure that Hard Disk Drive 1 and Hard Disk Drive 2 in the Setup Utility
are connected to the primary hard disk drive connector J9 on the Type
A-1 system board, and J5 on the Type A-2 system board.
2. Check the hard disk drive jumper settings (see “Parts/Test Point
Locations” on page 5-1).
3. Check the voltages to the disk drive power connectors with the power
on (see “Power Supply” on page 2-35).
