I THINK I KNW!
heheheh get a controller card...yes...
if you share the main OS harddrive w/ ANY drive....then be prepared for a slow boot...yes get a controller card to fix this problem....coimputer probably has a harddrive, burner, dvd...and only 2 slots on hdd...if u can't get a controller card, share both the drives on a single cable and make sure the hdd is connected w/ a 80pin cable! not 30!
well, hope those helps.....lemme knw!
