Keyboard
Controller / Gate A20 Failure
|
Try
re-seating the keyboard controller chip. If the error still occurs,
replace the keyboard chip. If the error persists, check parts of the
system relating to the keyboard, e.g. try another keyboard, check to see
if the system has a keyboard fuse.

Indicates a
memory error on the video adapter. Try re-seating the video card. If it
still beeps, try replacing the video card or the memory on the video
card.

|
ROM BIOS
Checksum Failure
|
Indicates
faulty BIOS chip(s). It is not likely that this error can be corrected by
re-seating the chips. Consult the motherboard supplier or an AMI product
distributor for replacement part(s).

Problem
|
Solution
|
|
CH-2 Timer
Error
|
Non fatal.
Could be caused by a peripheral.
|
|
|
INTR #1 Error
|
Interrupt
Channel 1 has failed the POST test
|
Check system
boards for IRQs 0-7.
|
|
INTR #2 Error
|
Interrupt
Channel 2 has failed the POST test
|
Check system
boards for IRQs 8-15.
|
|
CMOS Battery
State Low
|
|
Replace
battery.
|
|
CMOS Checksum
Failure
|
A checksum is
generated when CMOS values are saved for error checking on subsequent
startups. This error message will appear if the checksum is different
from one boot-up to the next.
|
Run the setup
program again to correct the problem.
|
|
CMOS Memory Size
Mismatch
|
Usually
caused when you add or remove memory from your system but could be caused
by memory that has failed.
|
Run setup.
|
|
CMOS System
Optons Not Set
|
CMOS values
are either corrupt or do not exist.
|
Run Setup.
|
|
Display
Switch Not Proper
|
Many
motherboards have a jumper setting that allows you to specify whether you
have a color or monochrome monitor.
|
Correct the
switch position.
|

Keyboard is
locked ... Unlock it
|
|
Unlock the
keyboard.
|
|
Keyboard
Error
|
There is a
problem with the keyboard
|
Make sure
your keyboard BIOS is compatible, that the keyboard is plugged in
completely, and that no keys are stuck. Or, change the BIOS keyboard
setting to "Not Installed" to skip the test.
|
|
K/B Interface
Error
|
There is a
problem with the keyboard connector on the motherboard.
|
|
|
FDD
Controller Failure
|
The BIOS
cannot communicate with the floppy drive controller.
|
The floppy
may be disabled, also check that the cable is not loose.
|
|
HDD
Controller Failure
|
As above, but
for hard disks.
|
|
|
C: Drive
Error
|
The system
cannot get a response from drive C.
|
The hard disk
type is most likely set incorrectly, or the disk may not be formatted or
connected properly.
|
|
D: Drive
Error
|
Same as above
except for drive D.
|
Same as
above.
|
|
C: Drive
Failure
|
The drive was
detected but failed. More serious than error.
|
|
|
D: Drive
Failure
|
Same as
above.
|
|
|
CMOS Time and
Date Not Set
|
|
Run Setup
|
|
Cache Memory
Bad, do Not Enable Cache!
|
|
Cache may
indeed be bad, if so replace. May simply need re-seating.
|
|
8042 Gate-A20
Error!
|
The Gate-A20
portion of the keyboard controller has failed.
|
Replace the
keyboard chip (8042)
|
|
Address Line
Short
|
There is a
problem with the memory address decoding circuitry.
|
Try
rebooting, (turn the system off and then on 10 seconds later). The
problem may correct itself.
|
|
DMA #1 Error
|
There is an
error in the first DMA channel on the motherboard
|
Could be
caused by a peripheral device.
|
|
DMA Error
|
There is an
error within the DMA controller on the motherboard.
|
|
|
No ROM Basic.
|
There is
nothing to boot from. (i.e.- the system cannot find an operating system).
|
Be certain
that a bootable disk is defined in the system setup.
|
|
Diskette Boot
Failure
|
The diskette
in the specified boot-up drive is corrupt.
|
|
|
Invalid Boot
Diskette
|
Same as
above, but the disk is readable.
|
|
|
On Board
Parity Error
|
There is a
parity error with memory on the motherboard at address XXXX (hex). (On
Board specifies that the memory is not on an expansion board, but rather
is located on the motherboard physically).
|
Possibly
correctable with software from the motherboard manufacturer. (also do a
Virus Check - some viruses cause parity errors).
|
|
Off Board
Parity Error
|
There is a
parity error with memory installed in an expansion slot at address XXXX
(hex)
|
Same as
above.
|
|
Parity Error
|
There is a
parity error with memory somewhere in the system.
|
Same as
above.
|
|

Memory
mismatch, run Setup
|
|
Disable
Memory Relocation if possible.

Devices that
depend on the fail-safe NMI timer are not operating correctly.
|
|
|
ID
information mismatch for Slot X
|
The ID of the
EISA expansion board in slot X does not match the ID in CMOS RAM.
