I've been attempting to install NW6.5 with the SP6 overlay CD. Everything
went great and I thought I had a new server. Then, when I rebooted, it
never got past stage 1 - looking for drives/partitions.

I have a SATA RAID 5 array with an Adaptec RAID card. I didn't install
drivers during the install and am guessing at what is hosed.

Is this a driver issue?

Can I replace these by going to DOS and replacing HAM/PSM files?

Do I need to start over from scratch and load correct drivers somewhere
during the install?

All help is always appreciated.
