Install on hardware RAID dualboot with Win7

Hi
I have read some threads about this but most of them were some years old and maybe things have changed.
I have set up my mobo for RAID0 and I'm running windows 7 on it right now. I like to dualboot with arch. But in cfdisk I see both hdd:s. Is it possible to see only one like I'm doing in windows? Or is it possible to install it with software RAID when I have my mobo set up on RAID? I tryed but could not get it to work.

thanks
Ato

Which raidcontroller do you use?

Look into dmraid, and check the wiki. It's possible, to a certain extent - I hope you're aware of the drawbacks such 'RAID' controllers have.

Okej, I'll try dmraid.
I can't find the right module for my chipset. I have an ATI SB600. Can you help me?

And what are the drawbacks of such RAID controllers?

The drawbacks are that the RAID Controller doesn't have his own processor and it uses the cpu.

What module? Or what is not working?

Re: Install on hardware RAID dualboot with Win7

This is from the wiki about Fake-RAID

# modprobe dm_mod
# modprobe sata_sil (or whatever chipset driver you need)
# dmraid -ay
# ls -la /dev/mapper/

It says: "or whatever chipset driver you need"
I guess the sata_sil is for some silicon image RAID chip, or does it work with my RAID controller that I think is built in to the southbridge SB600

Re: Install on hardware RAID dualboot with Win7

What is the output of

$ lspci| grep -i raid

?

Re: Install on hardware RAID dualboot with Win7

I found something about SB600 support at http://linuxmafia.com/faq/Hardware/sata.html#ahci and http://hardware4linux.info/module/ahci/.  It doesn't look like it supports RAID 5 (stripe w/ parity) maybe for a lot of the controllers, but I imagine it'ld be fine if you are running 0 (stripe) or 1 (mirror).

If you need to manually load a module, then I'ld try loading dm_mod and the ahci module and then do the `dmraid -ay` and see if anything shows up in /dev/mapper.

Correct, sata_sil is for a Silicon Image chip.
