I would also like to get Linux-drivers for ich10r, or prefferably a linux-version with drivers built in. I do not have such a motherboard, but I want to set up a fileserver. I am a n00b in Linux, my main competanse would be DOS.. secondary windows or Novell.
I would like for someone to check out this download from Intel:

If I understand it correctly it seems they intend for this to be a driver for most intel RAID sets- including the ICH10r- for linux (they mention specifically red-hat and suse, would I assume correctly that it should work in all other linuxes aswell??) I would love feedback as to the general functionality of that driver.
when it comes to the BIOS question, I might be able to help (assuming I understood you correctly,and assuming your motherboards built in RAID functions similar to my ICH8r on my asus P5B-e motherboard):
The basic BIOS on the computer only contains two settings that relate to the RAID. I do not remember exactly where in the BIOS those settings are hidden, but one is to tell the BIOS that the SATA discs is to be used as RAID (other options is IDE, and AHCI).. The other setting is one that actives/deactivates the RAID BIOS for the ICH chip. When it has been activated you need to reboot and wait until the primary BIOS is done. that is when the RAID Bios starts up and tells what discs are installed on the ports of the raid-controller.. press shift-r or shift-b or whatever it tells you to press to enter the RAID-bios. and voila, that is where you set up the raid-settings.
