BIOS modernization problem

[billionaiire]

I have a ASUS K8N (nForce 3 250GB chipset) motherboard.

It originally had AMIBIOS version 1009. But, due to some memory timing issues, I downgraded the BIOS to 1006 using ASUSUPDATE utility in Windows XP.

Now, each time the computer starts, it says "Flash Chip not supported"

Amazingly enough, the computer works absolutely fine, and the memory timings are displayed (don't know whether they actually work at that frequency) correctly.

Every attempt to reflash the BIOS back to 1009 or above failed.

The ASUSUPDATE utility fails to start, and Windows throws a BSOD if I click on that program

On other flashing utilities, it says "flash chip not present", "size mismatch" or "asus mobo not present" (this in case of window based utils).

Surprisingly this has happened once before, and I was able to reflash it using Ctrl + F2 which takes BIOS file from bootable asus driver disk. Now I can't.

Any help by the GURUS? any utility which forcibly updates the BIOS? any gains by removing the BIOS chip and reinserting it and stuff like that?

hi,

I've got the same problem as billionaire

After downgrading the BIOS to 1006 using ASUSUPDATE utility in Windows XP, I was not able to boot up the system.
I dont know what was is the problem.
I have tried with the other updates from the ASUS website and other resources, and updated my BIOS chip.
But the same problem exists.
Please help me.

Thanks

Most probable cause is that the BIOS release your system came with supports the physical BIOS chip that's in it. Older BIOS releases may not include the internal programming routines of that particular BIOS chip model, which only the newer revisions do.

Thanks for the prompt reply.
I have reprogrammed the bios by means of external IC prog. machine and now it is working fine, and I am able to update the new Bios files also.


Thanks

does someone has a alternative way to fix the bios?

and akku, is your memory timing back at DDR400 instead of DDR333?

Hello Everybody,

I have the same problem.

Akku, how did you do it?
What does it take to do it? I mean, software, hardware...

I'm not an experienced programmer....
Thank you.

http://www.badflash.com is the easiest route to follow.

Else you need an external eeprom programmer device with software and capable of flashing these chips.
