I recently purchased an ASUS M1AA.
ESXi won't pick up the storage on the machine and i believe this to be because there is some kind of software RAID configured in the BIOS. My NAS box has broken and i need to find a way to get ESXi to pick up the storage on the machine.
If i could find a way to break the RAID, then that would be the answer as then the disks would appear as standard SATA disks. I cannot find anywhere in the BIOS that references RAID.
