If you just would have looked around you would have found out in like five seconds what the difference was between the too. .06 is if you have an Hdd under 137 gb .67 is for 137+ gb dirves, so you would flash your bios with .06 for right now because you dont have a drive that is 137+ gb then after you get you 200gb drive reflash your bios with .67. If you have IND bios 5003 or maybe the newest xecuter bios you can just flash you bios with .67 and it wont hurt anything. I would help more but i have to go.
