If you are trying to use the RAID feature of the hpt370 on your KA7-100 you need to do what I did just 2 days ago... download the ka7_ry.b03 beta bios from abit's FTP site or one of it's mirrors (/pub/beta/ka7 directory I believe...) If you're going to install win2k on the RAID array make sure you get the latest win2k hpt370 driver from highpoint-tech.com... it fixes the INNACCESSIBLE BOOT DEVICE error that was given with earlier drivers.
