Troubleshooting Without Diagnostics
Solution
Check cable connections.
1. Run Computer Setup.
2. If the system still does not
recognize the new device,
check to see if the device is
listed within Computer Setup. If
it is listed, the probable cause is
a driver problem. If it is not
listed, the probable cause is a
hardware problem.
3. If this is a newly installed drive,
enter Setup and try adding a
POST delay under Advanced
> Power-On.
If the drive is a secondary drive that
has just been installed on the same
cable as the primary drive, verify
that the jumpers for both drives are
set correctly.
Run Computer Setup and enable the
Primary and Secondary IDE (ATA)
controllers in Storage > Storage
Options.
Run Computer Setup and increase
the POST Delay in Advanced >
Power-On Options.
Remove the diskette from the diskette
drive.
1. Insert a bootable diskette into
the diskette drive and restart the
computer.
2. If the hard drive is still
inaccessible and MBR Security
is enabled, try restoring the
previously saved MBR image by
entering Setup and selecting
Security > Restore Master
Boot Record.
