Award BIOS Error Codes
http://www.award.com/

During the power-on self test (POST), the BIOS either sounds a beep code or displays a message when it detects a correctable error.

Following is a list of POST messages for the ISA BIOS kernel. Specific chipset ports and BIOS extensions may include additional messages. An error message may be followed by a prompt to press F1 to continue or press DEL to enter Setup.

1.Beep
Currently the only beep code indicates that a video error has occurred and the BIOS cannot initialize the video screen to display any additional information. This beep code consists of a single long beep followed by two short beeps. Any other beeps are probably a RAM problem.

2.BIOS ROM checksum error – System halted
The checksum of the BIOS code in the BIOS chip is incorrect, indicating the BIOS code may have become corrupt.
Contact your system dealer to replace the BIOS.

3.CMOS battery failed
CMOS battery is no longer functional. Contact your system dealer for a replacement battery.

4.CMOS checksum error – Defaults loaded
Checksum of CMOS is incorrect, so the system loads the default equipment configuration. A checksum error may indicate that CMOS has become corrupt. This error may have been caused by a weak battery. Check the battery and replace if necessary.

5.CPU at nnnn
Displays the running speed of the CPU.

6.Display switch is set incorrectly.
The display switch on the motherboard can be set to either monochrome or color. This message 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.

7.Press ESC to skip memory test
The user may press Esc to skip the full memory test.

8.Floppy disk(s) fail
Cannot find or initialize the floppy drive controller or the drive. Make sure the controller is installed correctly. If no floppy drives are installed, be sure the Diskette Drive selection in Setup is set to NONE or AUTO.

9.HARD DISK initializing
Please wait a moment… Some hard drives require extra time to initialize.

10.HARD DISK INSTALL FAILURE
Cannot find or initialize the hard drive controller or the drive. Make sure the controller is installed correctly. If no hard drives are installed, be sure the Hard Drive selection in Setup is set to NONE.

11.Hard disk(s) diagnosis fail
The system may run specific disk diagnostic routines. This message appears if one or more hard disks return an error when the diagnostics run.

12.Keyboard error or no keyboard present
Cannot initialize the keyboard. Make sure the keyboard is attached correctly and no keys are pressed during POST. To purposely configure the system without a keyboard, set the error halt condition in Setup to HALT ON ALL, BUT KEYBOARD. The BIOS then ignores the missing keyboard during POST.

13.Keyboard is locked out – Unlock the key
This message usually indicates that one or more keys have been pressed during the keyboard tests. Be sure no objects are resting on the keyboard.

14.Memory Test :
This message displays during a full memory test, counting down the memory areas being tested.

15.Memory test fail
If POST detects an error during memory testing, additional information appears giving specifics about the type and location of the memory error.

16.Override enabled – Defaults loaded
If the system cannot boot using the current CMOS configuration, the BIOS can override the current configuration is a set of BIOS defaults designed for the most stable, minimal-performance system operations.

17.Press TAB to show POST screen
System OEMs may replace the Award BIOS POST display with their own proprietary display. Including this message in the OEM display permits the operator to switch between the OEM display and the default POST display.

18.Primary master hard disk fail
POST detects an error in the primary master IDE hard drive.

19.Primary slave hard disk fail
POST detects an error in the secondary master IDE hard drive.

20.Resuming from disk, Press TAB to show POST screen
Award offers a save-to-disk feature for notebook computers. This message may appear when the operator re-starts the system after a save-to-disk shut-down. See the Press TAB … message above for a description of this feature.

21.Secondary master hard disk fail
POST detects an error in the primary slave IDE hard drive.

22.Secondary slave hard disk fail
POST detects an error in the secondary slave IDE hard drive.

If the above suggestions fail to cause any change in the disfunction of the system, the motherboard should be returned for repair.


Your CMOS Information Is Important
Many users have old hard drives in their computers and have never written down their BIOS configuration–usually a custom one. For the newest hard drives, autodetect works and the drive (or the Internet) has the information, but this is usually not the case for older drives. I would recommend that these users have all this information printed in case of disaster (or in case the BIOS battery dies!)”

You’re thinking of the CMOS information, not the BIOS. The CMOS (Complementary Metal Oxide Semiconductor) chip is battery-powered and stores the hard drive’s configuration and other information. When the PC is turned off, battery power maintains the CMOS data.

The battery could someday lose its charge, or for some other reason the data might become corrupt. Check your owner’s manual to determine how to access the CMOS at bootup–usually by pressing the Delete key; a function key; or perhaps some combination of keys, like Ctrl-Alt-Esc, Ctrl-Alt-S, Ctrl-Alt-Ins, and so forth.

Some PCs do not have the setup program built in; it’s on a separate disk. Check your owner’s manual for the actual CMOS setup. You’ll need to know the information for your hard drive if the CMOS data get corrupted later, so if this info is not in the manual, write it there in case you ever need it.
