Confusing RAID behavior
I have just set up 2 new 250Gb SATA HDDs on my Asrock Geforce6100/MCP410-based motherboard. My plan was to raid, and install windows, mandriva x86 and x86-64 and debian. Windows installed ok (after I dug out my CD coz the drivers given on the asrock website dont work with windows install), but then I realised linux was not going to be that easy.
Basicaly I now have Mandriva installed on an old 8Gb HDD, and I have run across some confusing behavior. Basicaly, I can only see my raid set from linux (using dmraid) if I *DISABLE* the raid setting in the BIOS. Also, if the BIOS is set to RAID, even IT doesnt know there are 2 SATA disks there (probably why devmapper cant see them), but windows works fine.
Any suggestions would be most appreciated.
