Problem with Duron 650.

[dixx]

I have an Abit KT7-RAID and my Duron 650.
I downloaded an older version of bios after installing a beta bios.
Now my system stops working after counting the SDram.

How can i fix this???

Ouch, sounds like a bad BIOS or a bad flash!
You need to get a new BIOS chip from ASUS, which will cost money.
Another posibility, which I havent tried yet, and don't want to have to either, is get another A7V mobo, boot into DOS, run aflash and load a BIOS, replace the BIOS chip with yours while power is still on, Flash your chip, turn power off and move the BIOS chips to their respective boards.
You may also be able to use an EEPROM writer, but you probably don't have access to one.
