I am presently running this system on a Silicon Image 3112 based 
SATARaid card "SATA3112-150R" (cost AU$ 35). This is marketted in 
Australia under the "Connectland" name as a PCI Serial ATA Host 
Controller Card, however I'm sure it is marketted elsewhere in the world 
under a different company name as it's a generic card. There are RAID 
and non-RAID versions of this card, so make sure you get the one that 
says SATA RAID on the top of one of the chips. It is a hardware RAID-0/1 
(striping/mirroring) only card and the configuration is by pressing F4 
when prompted at start up, when a menu is displayed to configure the 
disks. This part is in the cards BIOS and hence OS agnostic.

At present I only have one SATA drive, so I'm not yet running either of 
the two RAID options.

The questions arise of how one accesses and controls the RAID Array from 
the Operating system. This is where the driver could give some support 
issues passing through commands. At least in my case, the management 
program supplied is pure JAVA so it "should" run under OS/2 or eCS 
without any problems, but it may not be able to pass its commands down 
to the controller via the Dani driver (I simply don't know at this stage 
- it "may" work).

If you don't mind having to reboot if you want to chack or change your 
RAID configuration, you shouldn't need to install any software under 
OS/2 as the BIOS based control program allows all required functions.

Cheers/2
