For the answer to the question:
For my AS-Rock, yes I'm trying to run off my IDE and force format the SATA from a fully operational Windows XP; SP2, with the most current RAID for the P4V88. Yet I cant seem get them to recognize on either.
For the Gigabyte, no, trying to run directly from the SATA.
For the Asrock: Did you check that SATA is enabled in BIOS and install the Windows SATA drivers?
For the Gigabyte, in BIOS enable SATA. Some mobos also have a BIOS setting to emulate IDE. If not, you will have to install the SATA drivers from floppy when installing Windows.
