Description
A parity error was found in the system bus (Parity
Check 1) or the I/O bus (Parity Check 2). BIOS
attempts to locate and display the address on the
screen. If it cannot locate the address, it displays.
Displayed after any recoverable error message.
Optional message displayed during POST. Can be
turned off in Setup.
Previous POST did not successfully complete.
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 wait-state configuration is
correct. This error is cleared the next time the
system is booted.
Real time clock fails BIOS test. May require board
repair.
Shadow RAM failed at offset nnnn of the 64K block
at which the error was detected.
Where nnnn is the amount of shadow RAM in
kilobytes successfully tested.
The CMOS clock battery indicator shows the
battery is dead. Replace the battery and run Setup
to reconfigure the system.
The system BIOS is copied to shadow RAM.
The RAM cache failed the BIOS test and BIOS has
disabled the cache.
The system CMOS has been corrupted or
incorrectly modified, perhaps by an application
program that changes data stored in CMOS. Run
Setup and reconfigure the system either by getting
the default values or making your own selections.
The system RAM failed at offset nnnn of the 64K
block at which the error was detected.
Where nnnn is the amount of system RAM in
kilobytes successfully tested.
