POST Beep Codes and Error Messages
When the system BIOS encounters an error that requires your attention, it will emit a
beep code or display an error message.
POST Beep Codes
Beep Code 1 consists of a single long beep followed by three short beeps. It indicates
that a video error has occurred and the BIOS cannot initialize the video screen to
display any additional information.
When this happens, perform the following steps until you solve the problem:
1.
Make sure the monitor is receiving power.
2.
Make sure the monitor cable is properly connected.
3.
Make sure the video card is properly seated in its slot.
4.
Try another power cord.
5.
Try another monitor.
6.
Try another video card.
7.
If that still doesn't solve the problem, call your Unisys Customer Service
Engineer.
Beep Code 2 consists of a single long beep that repeats itself. It indicates that a
DRAM error has occurred. When this happens, perform the following steps until you
solve the problem:
1.
Make sure each DRAM chip is properly seated in its slot.
2.
Make sure the DRAM chips are properly configured. See Table A-3 for all
possible configurations.
