nVidia driver install at DOS

Hello,
I have Windows Vista RC1. Everything worked fine until I installed an Asrock ALIVENF6G-DVI motherboard. Now, I get an error that says “can’t find drive to erase data” at begining of install. I have a Maxtor SATAII hard drive, just one, no RAID. How can I install the nVidia SATA drivers at the F6 in DOS or should I try the RAID drivers with just one drive? Thanks in advance for your help.
