6/2 LS700 HANDBOOK
If POST detects a hardware fault, one or more POST error
codes and messages are displayed
.
Your first action should be
to turn off the computer, wait at least 30 seconds, and then
turn it on again to see if the error is transitory or persistent.
Persistent POST errors may indicate a fault in the system.
♦
Check that all external cables are securely connected.
♦
Try running the BIOS Setup utility to reconfigure the
system.
♦
Open up the system unit and check that all internal
signal and power cables are securely connected.
If the problem persists, call your supplier or authorised
maintainer.
Failure to boot
On completion of POST, the computer attempts to boot
from a system diskette or bootable hard disk. Some of the
messages that might appear during the boot sequence:
Boot failure message
Explanation
Non-system disk or disk
error
The diskette drive contains a non-system diskette.
Replace it with a system diskette and press F1.
Diskette read failure
The diskette is either not formatted or defective. Replace
it with a system diskette and press F1.
No boot sector on fixed
disk
The hard disk has no active, bootable partition or is not
formatted. Insert a system diskette, press F1, and format
the hard disk as described in your operating system
manuals.
Fixed disk read failure
The hard disk may be defective. Press F1 to retry. Make
sure the drive is correctly specified in the BIOS setup
utility. If the problem persists, insert a system diskette,
press F1, backup the data held on the defective hard disk
and try reformatting it.
No boot device available
This may indicate a fault in the diskette or hard disk
drive, or perhaps a damaged system diskette. Make sure
that the Startup Device options are correctly specified
with the BIOS Setup utility. If the problem persists
contact your supplier or authorised maintainer.
