Description
The hard disk is not working or is not configured properly. Make sure the disk is installed
properly. Use BIOS Setup to make sure the hard disk type is correctly identified.
A key is stuck on the keyboard.
The keyboard is not working.
The keyboard controller failed its test. The motherboard may need to be replaced (the
motherboard contains the keyboard controller).
Unlock the system to proceed.
The monitor type is not correctly identified in BIOS Setup.
Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.
System RAM failed at offset nnnn of in the 64k block at which the error was detected.
Extended memory is not working or is not configured properly at offset nnnn. Update to the
latest BIOS version.
The CMOS clock battery indicator shows that the battery is dead. Connect the AC adapter for
at least 24 hours; replace the CMOS battery; replace the motherboard.
System CMOS has been corrupted or modified incorrectly, perhaps by an application that
changes data stored in CMOS. The BIOS installed default Setup values. If you do not want
these values, enter Setup and enter your own values. If the error persists, check the CMOS
battery. Connect the AC adapter for at least 24 hours; replace the CMOS battery; replace the
motherboard.
The timer test failed. Replace the motherboard.
The real-time clock failed the BIOS test. The motherboard may need to be replaced.
The previous POST did not complete successfully. POST loads default values and offers to
run BIOS Setup. If the failure was caused by incorrect values and they are not corrected, the
next boot will likely fail. This error is cleared the next time the system is booted.
The memory size found by POST differed from CMOS.
Drive A: or B: is present but fails the BIOS POST diskette tests. Make sure the drive is
defined with the proper disk type in BIOS Setup, and that the drive is installed correctly.
The type of floppy drive A: is not correctly identified in BIOS Setup.
The type of floppy drive B: is not correctly identified in BIOS Setup.
The RAM cache failed and BIOS disabled the cache. The motherboard may need to be
replaced. A disabled cache slows system performance considerably.
CPU socket number for Multi-Processor error.
ServerBIOS2 test error: cannot write to EISA CMOS.
ServerBIOS2 test error: Cannot write to extended DMA (Direct Memory Access) registers.
ServerBIOS2 test error: Cannot generate software NMI (Non-Maskable Interrupt).
