Nite-time, did you format your drive to NTFS when the win 2k installation prompted you to, if you did you'll have to format your drive as you cannot revert back to fat32 and windows 98 will not run on ntfs. I know this because i did the same thing DOH!!!
if you still are formatted to fat or fat32 then you can do an install of 98 and have a dual boot partition on your drive, this is probably the best solution
hope this has been help.
Also about rogue spear i heard that there maybe something wrong with soundblaster drivers that are affecting the keys i have the same problem and so does everyone else i know with soundblaster live!
