I have a had similar problem

I have a had similar problem with one of test machines which we use for Windows ME and 98. The problem was solved by replacing the motherboard battery and using a disc to flash the memory.

Possible causes

I could imagine a few possible causes.

  • The clock buffer battery on the motherboard ran empty. You may have to replace it.
  • The BIOS CMOS area got damaged, overwritten, or some such. Go into the BIOS settings, reset them all to their defaults, then store the settings.
  • The BIOS Flash memory got damaged. That's more difficult, but you could re-flash the BIOS by putting a flasher program like AWDFLASH.EXE and a new BIOS file on a bootable diskette.

In your message above, was the missing E at the end of "AWDFLASH.EX" a typo? Otherwise you may have a wrongly named file that needs to be renamed to: AWDFLASH.EXE

If all that doesn't help, things are becoming difficult and the prospect of having to buy a new motherboard or a new computer rises.

Good luck---Hans-Georg

Thanks for your comment
When the computer start, It cannot display any information about the motherboard. It directly display the above said message. We cannot even go to the BIOS setting. Is there is any other thing we can do? From where we are going to download the AWDFLASH.EXE

Thanks and eagerly waiting for your response

From the manufacturer of the motherboard

Usually you can download a flash utility and the latest BIOS version from the web site of the manufacturer of the motherboard or, if it is a brand computer, from its manufacturer.

The procedure of re-flashing the BIOS is to have a bootable diskette (or CD) with the flash utility and the latest BIOS on it. Then you boot from it, start the flash utility, and follow the menus and instructions to load the BIOS code onto the motherboard.

I think it is likely that the battery on the motherboard has to be renewed also, if it is now 9 years old.

I don't know what the sticker saying, "Phoenix BIOS" refers to, but apparently not to the motherboard BIOS, because that is obviously from Award, which is a different company.

On top of all of this you are running a small risk that the flash memory itself (or something related to it on the motherboard) is defective. Flash memory doesn't live forever. There is the possibility that re-flashing will not solve the problem.

Yet another risk is that the manufacturer will no longer support the motherboard, because it is too old. If you cannot find the required versions on their web site, you could perhaps ask them directly for support by email.

If all this fails, you're in for a new computer, which isn't that bad, considering the age of the old one. You will most likely be able to read all your data from the old hard disk, by connecting it to the new computer. Installed programs are another matter, but most of them will probably have to be upgraded and newly installed, because the new computer will have a newer operating system like Windows Vista or XP.

same problem

I'm having the same trouble, I have the AWFLASH.EXE and the latest bios loaded on a bootable floppy and when I load it the flash utility open but down on the bottom it says message: and next to that it says source file not found and the cusser seems to be stuck next to that on the outside edge of the box making it unable to navigate or type, any thought on that would be appreciated.
Thanx Crashaxe

BIOS file

Tue, 2008-05-20 05:24 by admin

Is it really the right BIOS file? Does it have the proper length? Is it the latest AWFLASH version? It should work.

BIOS file

Tue, 2008-05-20 23:02 by crashaxe

Well I went to Asus and got the file and the flash utility from there, I even tried the flash utility from the motherboard disk and it doesn't work at all. I'm working on an Asus A7N8X-E Deluxe board, by the way...
I even tried the first version of the bios, now am I doing this correctly?
I have a bootable floppy with the flash utility in this case AWDFLASH and the bios file on the disk and when I turn on the computer it goes to the utility and locks as described above. At this point I am getting brave and will try anything after all what do I have to lose that I haven't lost already...lol...

General hints

I don't know this particular problem, but I also use Asus motherboards and am writing this on an Asus laptop (in Nairobi, Kenya :-). For me the Asus BIOS flash utilities always worked.

Be sure you have exactly the right one for your motherboard. Unfortunately Asus is much worse at providing support, like on their dreadful web site, than building stuff.

You could also ask in the matching Asus user forum, if you can find it in the first place. You won't get an answer from Asus, but most likely some good answers from other users. The forums are somewhere on one of their web sites.

Good luck.

The following worked for me

Sun, 2008-01-20 02:15 by saxman2

Had the same problem after attempting a bios update on a customers' Gigabyte GA-7VA rev.1 using the @BIOS windows utility from the manufacturer.

When the PC was rebooted I recieved "BIOS ROM Checksum error
Detecting Floppy drive A media
INSERT SYSTEM DISK AND PRESS ENTER"

Tried several attempts with the DOS boot floppy and the manufacturer flash utility...no go.

Only thing that finally worked was a "open source" utility called "UniFlash" available here:
http://www.uniflash.org/
I setup the autoexec.bat file to run as is described in the download and it worked like a charm. READ the enclosed text files before attempting...As it says, "This is not for the fainted hearted..."

After reading several posts on this and other forums, and how fatal this error can be in many cases, I can't express enough how this utility saved my sanity...what an incredible relief it was.

which file

Tue, 2008-05-20 23:26 by crashaxe

Do I want the executable file or the source code.

I'll try anything

Tue, 2008-05-20 23:09 by crashaxe

I am researching this uniflash to see if it is possable for it to work on this board.
At this point this board is looking more and more like a shotgun target...lol...
Thank you all for your help and input I do appreciate it.
