Dmraid/grub and dual boot with sil3112 RAID

[spookymandias]

My first post here...

Tried a lot of linux distro's the last weeks... discovered I like fedora the best, but it has one problem that I really don't like. Being a complete Linux noob, currently the only working alternative is to switch to mandrake 10.1 which allows me to dual boot out of the box.

Configuration:

Fedora on an 40 GB Seagate IDE (linux filesystems)
Windows on 2*80 GB RAID 0 on SIl 3112A onboard RAID controller.

The only thing I want is to get GRUB so far as to give me an option allowing me to boot into windows...

Fedora recognises the drives, but doesn't think they are raid.

installed dmraid-1.0.0-rc5f.i386.rpm (forgot to google to the fc3 version, but don't think it would be a problem as I had the same problems a few days ago. ).

dmraid -cs reports no software RAID discs
dmraid -ay sil reports no software RAID discs
dmraid -rf sil reports two drives @ sil @ raid 0
dmraid -s sil reports no software RAID discs.

And when running in init 3, I get following error: program dmraid is using a deprecated SCSI ioctl, please convert it to SG_IO

snif... Why do I always ask the questions no-one can answer.

Anyway, can somebody explain why the mandrake 10.1/Lilo combo is able to do this, and fedora cannot?

Does anybody know a workaround (like using windows XP's bootloader to load fedora? And how should I do that then?)

Sounds like the SATA_SIL module is not being loaded, try:

modprobe sata_sil

Then run dmraid again.

If modprobe can't find that module, then you need to compile it and add it to the module dir for the running kernel. I'm sure you can discover the rest of the process with Google.

I have heard of lockups with these sata modules though, so beware.
