so if your using the latest bios it should work fine with a pair of 300gb drives
if you need to download the latest bios just follow the link below and click on "bios" and type in the model #

***EDIT*** i just noticed that the kkpr0826.exe is for the kk266plus-r not the plain kk266 (so the 48bit support that is mentioned is most likely for the highpoint integrated IDE controller) and if they have an updated bios that updates an addon controller then i would be very supprised if they hadnt previously updated the controller integrated into the southbridge.
so no guarantee, but i would imagine if you use the newest bios for your board it will have support for your 300gb drives
