Error Message Summary
The following table summarizes the most significant of the problems that
can be reported.
Beep Codes
If an error occurs during the POST, which prevents the PC Workstation from
starting, and before the display device has been initialized, a series of beep
codes are issued. Beep codes indicate that a fatal error has occurred and can
be reported one after another if there is more than one detected error. In
this case, the first detected error is the most important.
Message Explanation or Suggestions for Corrective Action
Operating system not found or all
devices have been checked and no
operating system has been found Check whether the disk, HDD, FDD or CD-ROM disk drive is
connected.
If it is connected, check that it is detected by POST.
Check that your boot device is enabled on the Setup Security
menu.
If the problem persists, check that the boot device contains the
operating system.
Missing operating system If you have configured HDD user parameters, check that they are
correct. Otherwise, use HDD type “Auto” parameters.
Resource Allocation Conflict -PCI device
0079 on system board Clear CMOS.
Video Plug and Play interrupted or
failed. Re-enable in Setup and try again You may have powered your computer Off/On too quickly and the
computer turned off Video plug and play as a protection.
System CMOS checksum bad - run
Setup CMOS contents have changed between 2 power-on sessions. Run
Setup for configuration.
No message, system “hangs” Check that the main memory modules are correctly set in their
sockets.
Other An error message may be displayed and the computer may “hang”
for 20 seconds and then beep. The POST is probably checking for a
mass storage device which it cannot find and the computer is in
Time-out Mode. After Time-out, run Setup to check the
configuration.
