114 Chapter 5 System diagnostics and troubleshooting
Cause
The system might not have
automatically recognized a
newly installed device.
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.
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).
Fixed-sync monitor does not
sync at the resolution
specified.
Computer is in Hibernate
mode.
Solution
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.
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.
Replace the hard drive.
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.
Press any key or press the mouse button, and, if set, enter
your password.
Reflash the ROM using a SoftPaq. (See Failsafe Boot
Block ROM section in Chapter 3.)
Be sure that the monitor can accept the same horizontal
scan rate as the resolution specified.
Press the power button to resume from Hibernate mode.
