Hi Guys I am having the same trouble with the adaptec SATA HostRaid driver. I have an embedded adaptec SCSi and SATA chipset that both support HostRAID. I am trying to get the SATA Hostraid to be supported so I can install XP, but everytime I add it with nlite, it wont see the drives. I got the drivers from IBM, so I would assume that they are certified, but how do I tell? Any other clues. Mick
