Hard Disk(s) Fail (80)

Hard Disk(s) Fail (40)

Hard Disk(s) Fail (20)

Hard Disk(s) Fail (10)

Hard Disk(s) Fail (08)

BIOS ROM Checksum Error

Memory Test Fail

CMOS Battery Has Failed

Probable Cause / Solution

CMOS battery is no longer functional. It should be replaced.

CMOS Checksum Error

Probable Cause / Solution

Checksum of CMOS is incorrect. This can indicate that CMOS has become corrupt. This error may

have been caused by a weak battery. Check the battery and replace if necessary.

Disk Boot Failure

Probable Cause / Solution

No boot device was found. This could mean that either a boot drive was not detected or the drive

does not contain proper system boot files. Insert a system disk into Drive A: and press Enter. If

you assumed the system would boot from the hard drive, make sure the controller is inserted

correctly and all cables are properly attached. Also be sure the disk is formatted as a boot device.

Then reboot the system.

Diskette Drives or Types Mismatch Error

Probable Cause / Solution

Type of diskette drive installed in the system is different from the CMOS definition. Run SETUP to

reconfigure the drive type correctly.

Display Switch Is Set Incorrectly

Probable Cause / Solution

Display switch on the motherboard can be set to either monochrome or color. This indicates the

switch is set to a different setting than indicated in SETUP. Determine which setting is correct, and

then either turn off the system and change the jumper, or enter SETUP and change the Video

selection.

Display Type Has Changed Since Last Boot

Probable Cause / Solution

Since last powering off the system, the display adapter has been changed. You must configure the

system for the new display type.

Error Encountered Initializing Hard Drive

Probable Cause / Solution

Hard drive cannot be initialized. Be sure the adapter is installed correctly and all cables are

correctly and firmly attached. Also be sure the correct hard drive type is selected in SETUP.

Error Initializing Hard Disk Controller

Probable Cause / Solution

Cannot initialize controller. Make sure the cord is correctly and firmly installed in the bus. Be sure

the correct hard drive type is selected in SETUP. Also check to see if any jumper needs to be set

correctly on the hard drive.

Floppy Disk CNTRLR Error or No CNTRLR Present

Probable Cause / Solution

Cannot find or initialize the floppy drive controller. Make sure the controller is installed correctly

and firmly. If there are no floppy drives installed, be sure the Diskette Drive selection in SETUP is

set to None.

Keyboard Error or No Keyboard Present

Probable Cause / Solution

Cannot initialize the keyboard. Make sure the keyboard is attached correctly and no keys are being

pressed during the boot.

If you are purposely configuring the system without a keyboard, set the error halt condition in

SETUP to A

ll, But Keyboard

. This will cause the BIOS to ignore the missing keyboard and continue

the boot.

Memory Address Error at

nnn

Probable Cause / Solution

Indicates a memory address error at a specific location. You can use this location along with the

memory map for your system to find and replace the bad memory chips.

Memory Parity Error at

nnn

Probable Cause / Solution

Indicates a memory address error at a specific location. You can use this location along with the

memory map for your system to find and replace the bad memory chips.

Memory Size Has Changed Since Last Boot

Probable Cause / Solution

Press F1 to reconfigure.

Memory Verify Error at

nnn

Probable Cause / Solution

Indicates an error verifying a value already written to memory. Use the location along with your

system's memory map to locate the bad chip.

Offending Address Not Found

Probable Cause / Solution

This message is used in conjunction with the

I/O channel check

and

RAM parity error

messages

when the segment that has caused the problem cannot be isolated.

Offending Segment:

Probable Cause / Solution

This message is used in conjunction with the

I/O channel check

and

RAM parity error

messages

when the segment that has caused the problem cannot be isolated.

Press A Key to Reboot

Probable Cause / Solution

This will be displayed at the bottom screen when an error occurs that requires you to reboot. Press

any key and the system will reboot.

Press F1 to Disable NM1, F2 to Reboot

Probable Cause / Solution

When BIOS detects a non-maskable interrupt condition during boot, this will allow you to disable

the NMI and continue to boot, or you can reboot the system with the NMI enabled.

RAM Parity Error

Probable Cause / Solution

Indicates a parity error in random access memory.

System Halted

Probable Cause / Solution

Indicates the present boot attempt has been aborted and the system must be rebooted. Press and

hold down the Ctrl and Alt keys and press Del.

Floppy Disk(s) Fail (80)

Probable Cause / Solution

Unable to reset floppy subsystem.

Floppy Disk(s) Fail (40)

Probable Cause / Solution

Floppy type mismatch.

Hard Disk(s) Fail (80)

Probable Cause / Solution

HDD reset failed.

Hard Disk(s) Fail (40)

Probable Cause / Solution

HDD controller diagnostics failed.

Hard Disk(s) Fail (20)

Probable Cause / Solution

HDD initialization error.

Hard Disk(s) Fail (10)

Probable Cause / Solution

Unable to recalibrate fixed disk.

Hard Disk(s) Fail (08)

Probable Cause / Solution

Sector verify failed.
