: usually to setup a hardware raid you'll need to run the manufacturers
: provided tool to register the disks and format the RAID partitions,
: once you've done that the disks should show up if you have working
: drivers.

yeah, I did that in xp, and it was working. 

Part of the issue is that its not a true hardware controller. Nearest I can 
tell, its what they call fakeraid. from what Ive read, it should be able to 
be used as a hardware raid with the sata_sis driver, but I havnt seen that 
yet. Another part of the problem is that the controller runs SATA, and IDE, 
and most ifnot all the docs ive read dont talk about setting up ide drives.


I can also set it up as just software raid (bypassing the raid bios i guess). 
but i havnt see that working under linux yet either.

also, I should mention, Ive tried removing the raid (in the raid bios), to use 
them as regular disks (which btw is mentioned in that sis SATA RAID manual), 
and I still cant see the disks...
 
Im not sure where they will appear, some docs I read mention /dev/ataraid, 
some /dev/md, or even /dev/hde, /dev/hdg. but ive seen none of that(although 
I have seen md, and ataraid in my dev dir...)

:
: Software RAID uses the host computer to manage all the parity checking etc.
: But since you have the hardware ...

yeah, from what Ive read, the linux software raid works better than these 
types of raid controllers... Right now, id settle for working! but i would 
like to compare and see for myself.

If I can figure out how to access the disks at all, it will be easier!

:
: you might want to check this manual
: http://www.sis.com/support/faq/SATA_RAID_manual.pdf
yep, read that. I have it on the computer for quick reference.... I aslo have 
all the other pdf's from sis, and asus related to this board.
