I have 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?
