Hi,
An hour or so spent googling this problem came up with a workaround.
The drives could be seen in Device Manager and the BIOS as stated above. They could also be seen under Admin Tools/Computer Management/Storage/Disk Management.
The SATA Drives were shown as "foreign" drives. There was a menu available when Rt Clicking one of these to "Import Foreign Drives".
It is now up and running, With 3 x 200GB SATA Drives, 2 x 200 Gb PATA Drives and two DVD Burners.
