Abit KN9 Ultra - NVIDIA MCP55 Ultra
First of all I would like to know if someone managed to use the RAID provided by this chipset with linux, I googled a little bit but couldn't find anything useful.
I have been trying for 2 months now and I am about to buy a PCI RAID controller because I really don't understand what the problem is.
My configuration is:
Abit kn9 Ultra
1 hd Seagate 320Gb
1 hd Maxtor 320Gb
Basically I entered the bios, enabled the RAID controller and the SATA channels, entered the raid utility (through pressing f10 during post) setup a new array specifying mirror mode, installed Debian sid on one HD without even partitioning the other disk (as what I want is a RAID1). After the installation at the reboot grub get stuck printing non-stop "GRUB loading stage 1.5"
The first thing I don't understand is: shouldn't linux see just one device once the array is up? Well, during the installation I could see sda and sdb.
Another strange thing (but of course this has nothing to do with linux) happens when I try to rebuild one disk from the RAID Utility (the screen get full of strange changing ascii signs in 8 colors - very impressive) and the only
wayout is to unplug the cord (screenshot is attached).
I changed the motherboard twice, after contacting Abit in Holland, they were sure it was a defect on the MB ....
At the moment I am trying with a GRUB bootdisk with the folloqing result:
Error 5: Partition table invalid or corrupt
if I type it again the output changes:
Filesystem type is ext2fs, partition type 0x83
I tried find /boot/grub/stage1 (error 15: file not found)
I tred setup (hd0) ... (Error 5: Partition table invalid or corrupt)
Finally if I disable RAID in the BIOS, GRUB works perfectly and my debian gets
up without any problem.
Any help is more than appreciated.
Abit KN9 Ultra - MCP55 Chipset RAID problem
it's me again still struggling with this MB.
Finally I got that the device is a fakeraid but
searching a little bit I found out also that should be AHCI
Abit keeps on saying there must be some conflicts with other
peripherals but I just don't understand a few things:
Why grub get stuck and cannot even load the kernel?
If it was a problem "driver-related" shouldn't I get an error
(eg. kernel panic unable to mount root) while loading the kernel?
Furthermore does anyone have a clue on why I get that weird screenshot
I attached in my last message when from the bios raid utility
try to rebuild the mirror?
Thanks a lot
