It does. One thing worth noting is that the chip has two modes. In

RAID mode it doesn't support CD-ROM devices but handles basic raid stuff

exactly like a standard IDE controller. Both modes are supported. RAID 0
is generally best done using software RAID in Linux, RAID 1 there are
advantages to doing it either way. Some of the RAID firmwares are a bit
flakey so if you get a problem boot it with the device in non-RAID mode.
(if the BIOS won't let you set it then try 'pata_it821x.noraid=1' as a
boot option.
Hmm. I have a belief that I'm not operating the controller in a RAID
mode, but I will double check. If I don't get anywhere in that
direction, I'll try the boot option you've suggested.
Thanks for your help. :)
