Anyway I have a laptop (Clevo D901C) with this controller. (its basically a desktop 965 chipset, with Q6600)
I get the "no raid disks found."
Here is the output of the mentioned command.

fdisk -u -l /dev/sda

Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors
Units = sectors of 1 * 512 = 512 bytes
Disk identifier: 0x06850684

Device Boot Start End Blocks Id System
/dev/sda1 * 63 104856254 52428096 7 HPFS/NTFS
/dev/sda2 104856255 209712509 52428127+ 7 HPFS/NTFS

/dev/sda4 837436320 1465160129 313861905 7 HPFS/NTFS

After doing "dd if=/dev/sda of=outputfile skip=488395168"
Here is some relevant text I found at the very end of the output file, which is attached.

Intel Raid ISM Cfg Sig. 1.2.01
21BB0F00WDG18AWApY
21BB0F00WDG0JSMApY
21BB0F00WDG0WXVApY
Volume0

I really hope I can get some form of 64 bit linux installed on my laptop without destroying my current RAID0.


Edit: I figured out that "Intel Raid ISM Cfg Sig. " is what the program looks for exactly, and it is in the last 2 sectors of the disk.
To fix this I am supposed to edit the isw.h file in the source code and recompile but since I am a n00b programmer I am not sure how to do this with the very complicated source code files.
