From the sounds of it it's fake raid. M$ doesn't leave any signatures
on their raid system that linux will detect. dm/md raid can see fakeraid signatures in newer versions so the installer may be picking up on that.

Have a quad core workstation that was running WinXP_64 that I want to blow away and install CentOS 6. C6 install process finds raid metadata associated with sda and sdb, and then excludes them from the rest of the installation process.
There doesn't appear to be an option for disassembling the raid as part of the install process. I think there should be.
Any tricks to removing/by-passing the soft raid left over from the previous OS?
Is this pure WinXP_64 software RAID or BIOS-assisted 'fakeraid'? If the latter, go into the BIOS and change its settings from 'RAID' to 'AHCI' or other 'native' SATA mode.
The only other thought would be to use a Live CD to clobber the disks (eg using fdisk or 'dd if=/dev/zero of=/dev/sda' or something). It might also be possible to get to a shell process with Alt-F2 in the installer and using fdisk, etc. to clobber the disks -- do this *before* screen where it asks about partitioning, etc.
