Upgraded to GA-7N4000 Pro2 . XP repair installation worked OK and boots to
XP Home OK with RAID option in BIOS disabled.

BIOS sees 80 Gig HD (ATA 100) on IDE 0, DVD Drive and DVD rewriter on IDE 1.

But if I enable RAID HW in BIOS it runs scan but no IDE drives detected on
IDE 1 to 4 ! Thus RAID config utility cannot be setup. If ATA option
selected under RAID in BIOS get same message.RAID utility and drivers
successfully installed and run in XP but again no IDE drives found.Have
flashed BIOS to F10 but still have problem. Was going to do clean install
but as problem shows in BIOS and before XP loaded did not see how would
cure.

Great MB otherwise.
