BIOS POST Messages
Description
Previous POST did not complete successfully. POST loads default values
and offers to run Setup. If the failure was caused by incorrect values and
they are not corrected, the next boot will likely fail. On systems with control of
wait states, improper Setup settings can also terminate POST and cause this
error on the next boot. Run Setup and verify that the waitstate configuration is
correct. This error is cleared the next time the system is booted.
Memory size found by POST differed from CMOS.
Drive A: or B: is present but fails the BIOS POST diskette tests. Check to see
that the drive is defined with the proper diskette type in Setup and that the
diskette drive is attached correctly.
Type of floppy drive A: not correctly identified in Setup.
Type of floppy drive B: not correctly identified in Setup.
RAM cache failed and BIOS disabled the cache. On older boards, check
the cache jumpers. You may have to replace the cache. See your dealer. 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).
ServerBIOS2 test error: Fail-Safe Timer takes too long.
Address conflict for specified device.
Run ISA or EISA Configuration Utility to resolve resource conflict for the
specified device.
CD ROM Drive identified.
Starting Setup program
The hex number nnnn is a map of the bits at the RAM address which failed the
memory test. Each 1 (one) in the map indicates a failed bit. See errors 230,
231, or 232 above for offset address of the failure in System, Extended, or
Shadow memory.
Fixed disk n (0-3) identified.
Problem with NVRAM (CMOS) data.
I/O device IRQ conflict error.
PS/2 Mouse installed.
