Display Codes
There are a number of Power On Self Test (POST) tests that are performed after the Beep Code tests. Failure of one or more of these tests will result in a displayed failure code (such as
03044). It is extremely important not to interpret a failure code immediately as a hardware failure. The failure should be confirmed with a clean boot. A clean boot is defined as pressing the reset button after removing all accessories (including additional memory, floppy drive, modems, PC cards, and printers) and providing a reliable power source. Note, make sure the display is adjusted to be visible.
The following tables lists common PC error messages. Not all of these messages will appear on every model of the OmniBook 800.
Table 3 - POST Display Codes
Message | Possible Cause |
CLOCK NOT TICKING CORRECTLY | The real time clock is not ticking. |
COLOR/MONO SWITCH INCORRECT | The COLOR/MONO switch on the system |
| board is incorrect for the installed |
| hardware. |
CMOS CHECKSUM INVALID - RUN SCU | CMOS RAM information has been |
| corrupted and needs to be reinitialized via |
| the System Configuration Utility. |
CMOS FAILURE - RUN SCU | CMOS RAM has lost power and needs to |
| be reinitialized via the System |
| Configuration Utility. |
FLOPPY CONTROLLER FAILED | The floppy controller failed to respond to |
| the reset command. Power down the |
| system and check all appropriate |
| connections. It the floppy controller |
| continues to fail, you may need to replace |
| it. |
FLOPPY DISK TRACK 0 FAILED | The floppy drive cannot read track 0 of |
| the floppy disk in the drive. Try another |
| diskette. If the problem persists, you may |
| need to replace the floppy drive. |
FLOPPY INFORMATION INVALID - RUN SCU | The drive parameters stored in CMOS do |
| not match the floppy drives detected in |
| the system. |
HARD DISK CONTROLLER ERROR | The hard disk controller failed to respond |
| to the reset command. Possible |
| solutions: 1) Check the drive parameters. |
| 2) Power down the system and check all |
| appropriate connections. If the problem |
| persists, you may need to replace the |
| hard disk controller. |
HARDWARE INFO DOES NOT MATCH VIDEO | The video adapter type specified in |
CARD - RUN SCU | CMOS RAM does not match the installed |
| hardware. |
KEYBOARD CONTROLLER FAILURE | The keyboard failed the |
| command. Check to see if the keyboard |
| controller is properly installed. If the |
| problem continues, replace the controller. |
