Finally decided to move on from my CF 52S mk4. Win7 64 bit on a 960gb SSD. Downloaded the driver bundle ahead of time. Direct swapped the caddy and SSD. Let win7 adjust, rebooted and ran the driver bundle. After all was good with win7 and no yellow flags, I swapped out the Intel 6235 for the Azurewave CE123 H from the mk4.
