108 Chapter 5 System diagnostics and troubleshooting
Cause
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
non-bootable diskette.
System is trying to start from a
damaged hard drive.
System files missing or not
properly installed.
Hard drive boot disabled in
Computer Setup.
Hard drive is damaged.
Cause
The cable connections are not
correct.
The monitor is off.
Screen blanking utility installed
or energy saver features
enabled.
System ROM is bad; system is
running in FailSafe Boot Block
mode (indicated by 8 beeps).
Solution
1. Run the Computer Setup (F10) Utility.
2. If the system still does not recognize the new device,
verify 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 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 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 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 system files for the appropriate operating
system if necessary.
Run the Computer Setup (F10) Utility and 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 127.
Solution
Verify the cable connections from the monitor to the
workstation and to a working electrical outlet.
Switch the monitor to on (LED is on). You might need to
refer to the monitor manual for an explanation of the LED
signals.
Press any key or click the mouse button, and, if set, enter
your password.
