Hi all,
I have an Asus A8N32-SLI Deluxe Mobo, which has an NVIDIA nForce4 sata
raid controller and I tried to install Debian with the testing
netinstall cd, but it does not recognize my RAID array. Any idea how to
do that? Googling I found this
(http://www.transtronics.com/reference/SATA-RAID-debian-for-2.6.html),
but it states that the debian installer should recognize raid arrays..
should it?
Cheers,

Hey,
A little bit of googling found this: http://ubuntuforums.org/showthread.php?t=178400
It's one guy's experience with an nforce4 chipset mobo. FTA:
" Step 1.) Disable Raid Support in Bios and and other type of "Software" Raid Controller. That nifty nforce 4 motherboard you have DOES NOT have a HW Raid controller. You will find that if you use that raid controller and try to get linux to play nice, you will fail miserably! "
From this and a few other pages it looks like you may be able to access the array using dmraid but not as a boot device and even if you could, it doesn't perform better than a software md raid because the 'hardware' raid the mobo uses actually uses the system cpu and memory anyway.
If you're dual booting and already have windows installed on the array then pursue the issue, otherwise it seems your time is better spent relaxing with a software raid soution.
cheers,
Owen.
