The ViA VT641x/642x are PCI to ATA/SATA chips. They seem to offer a "FRAID" (Fake RAID) BIOS option. There is basic, 16-bit BIOS boot-time/setup, but _no_ on-board hardware/firmware intelligence. 100% of RAID functionality is driven by your CPU with the FRAID driver -- i.e., software RAID.
I will have a look thanks as long as i can get it going that all I need .....>From what I've read, no Linux kernel seems to integrate the driver yet, at least not through 2.6.11. The Open Source (not GPL?) driver I found was here (see the bottom of the page): http://source.robertk.com/ ViA has their own, official driver that claims to work with the VT6410, VT6420, VT6421 here: http://www.viaarena.com/Default.aspx?PageID=2 There are 2 driver parts. One is called "viapubraid", which seems to be the "stub driver," open source and it builds against the kernel version. The other is "viaprvraid" which is object code (.o) only, much bigger (>100KiB), and likely the "FRAID IP" -- i.e., the RAID code is software and licensed from a 3rd party, which won't allow it to be open sourced. So not only is it a PITA to just work as "standard ATA" in Linux, but you can pretty much forget RAID.
