dm (linux device mapper) can understand several different software
raid formats (including 'fakeraid' that some motherboard bioses
If your bios/'hardware' is supported, you may just need to tell the
installation boot loader to load the right module and it's parameters.
try some of these:
OTOH, Windows XP can actually do software raid itself. So if you want
to just leave the bios/fakeraid out of the picture, you can configure
software raid for both windows and linux as you see fit.
Not all linux distro installers allow for a simple root-on-raid1
install, but as long as it allows you to get to a shell, you can
usually make them work.
I don't know if you can put C: on software raid1 in windows, but I
know you can easily create mirrors (and stripes) in windows. You can
even do it in Windows XP Home if you copy the appropriate dll from an
XP Pro install--the feature is in XP Home, just disabled/hidden.
