One of my systems has a fake-hardware RAID array and a solo disk with XP
installed using the Promise driver disk. I installed Ubuntu onto the solo
disk and choose the boot device (RAID or HDD 1) from the BIOS menu to decide
which OS I boot into. Ubuntu has never tried to mount the fake raid array -
doesn't even show it exists. YMMV.
