I have an Abit IC-7 Max3 motherboard with four WD Raptors in Raid 0. I would like to run Mandrake using an external drive via USB. I am thinking that this will allow me to use Linux without having to put any Linux data on my Raptor drives. I realize that I will have to change the first boot device in BIOS each time that I switch between booting on the internal and external drives. Will this work? Thanks for your help.
