updated Abit an8 sli to 2.1 slic now my vista won't boot I have an Abit an8 sli that I updated the bios to a 2.1 slic now my vista won't boot. I used a softmod to activate vista. The reason why I updated to a 2.1 slic is to install win7 with a bios mod. The system boots but hangs on the microsoft corporation screen with the flashing green bars. Any suggestions. Thanks. I am installing win 7 on another hard drive and need to keep my existing vista install for a while.
