Kurt - thanks so much. The drive is a PATA 750GB drive. I knew about the 137GB limit but understood that SP4 fixed that isssue which is why I tried just slipstreaming. The post for SP5 is brilliant. I haven't been to RyanVM's and used his sofware in quite a while. Absolute genius. May just cut to the chase with Acronis, partition then install and return to the integrated install later. I'm still concerned about the registry entry being entered enabling LARGELBA automatically or must be done manually before all can be seen by the opsys.
