How to fix a corrupted bios flashing?

[Kakao]

Hello. I am a new user and would like your help.
I have good knowledge to make a bios flash but....
I have the motherboard ASUS P4P800-E Deluxe and I have made a bad flashing bios(the tool asusupdate hasn't finished the upgrading-stuck). Nothing happent when i star it(no bip-no singal). I bought a new motherboard.

Can you help me? If you know how, then tell me any information I need to flash the bios such software, process, etc.

Because I couldn't wait for a reply, I tried it myself.

I made a disk with UNIFLASH and I start the pc to DOS.
After booting, I changed the good bios with the damaged and I tried to flashing the damaged bios.
Unfortunately, I didn't the bios flashing but I geting an error (Flash data verification error).

The progress bar was red except one green box.I tried all the options of UNIFLASH. Also I tried the afudos(asus) but I geting an error (compatible with existing Bios ROMID).

Can you help me to do Forced-Flash? This is my last choice.
If i can't find the four-digit code? Is there any general code for Forced-Flash?

Hey Kakao
Do you know that your motherboard supports CrashFree BIOS?
Take a look at http://www.ehow.com/how_5101013_use-crashfree-bios.html and follow the step by step procedure to update your corrupt BIOS Flash

Good Luck

You could try flashrom (http://www.flashrom.org/) under DOS/Linux/FreeBSD/NetBSD/MacOSX/whatever. If it finds the replacement chip, there's a good chance you can flash it.

The downloads there are source code only, so if you want a ready-to-use binary (.exe or whatever), you may have to ask on the flashrom mailing list or IRC.

If the flash chip crashes when verifying it is broken, which is also the reason the regular flash went wrong. Replace the flash chip for the P4P800-E Deluxe, buy new one.
