If you have the 2000 CD you can try two types of repair. The first is quick: Boot from the CD and select "repair." The second" Boot from the CD and select "Install." Be brave...it won;t install overthe old version--at least not yet, fist it will search your system and find your previous install...
I have that board and when I installed the most recent bios: the 1005, everything went to hell. Boot time and especially stability went very bad. I reverted to the 1004 and all is well. Please respond so I know that my fix really worked.
