Cause
The directory structure is bad,
or there is a problem with a file.
Loose cable.
The system might not have
automatically recognized a
newly installed device.
Drive jumper settings might be
incorrect.
Drive responds slowly
immediately after power-up.
System is trying to start from a
nonbootable diskette.
System is trying to start from a
damaged hard drive.
System files missing or not
properly installed.

Computer Setup.
Hard drive is damaged.
Cause
The cable connections are not
correct.
The monitor is off.
Solution
Right-click Start, select Explore, and select a drive.
Select File>Properties>Tools. Under Error-checking,
select Check Now.
Verify cable connections.
1. Run the Computer Setup (F10) Utility.
2. If the system still does not recognize the new device,
verify that the device is listed in the Computer Setup
(F10) Utility. 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 drive is newly installed, 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 the Computer Setup (F10 utility, and then 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 workstation.
2. If the hard drive is still inaccessible and MBR Security
is enabled, try restoring the previously saved
MBR image by entering Setup, and then selecting
Security>Restore Master Boot Record.
1. Insert a bootable system diskette and restart.
2. Verify that the hard drive is partitioned and formatted.
3. Install the system files for the appropriate operating
system, if necessary.
Run the Computer Setup (F10) Utility, and then enable the
hard drive entry in the Storage>Boot Order list.
Observe the beeps and LEDs on the front of the
workstation. Refer to POST error messages
on page 135.
Solution
Verify the cable connections from the monitor to the
workstation and to a working electrical outlet.
Switch the monitor on (LED is on). You might need to refer
to the monitor manual for an explanation of the LED
signals.
