I'll add a quick 'me too' to all the other replies to this thread so far ... If your BIOS supports USB booting, you should have no problem creating a bootable USB disk. I can send you Makefile fragments that I use to generate a bootable disk image I write to USB drives ... it's not really any different a process than booting from another disk medium (not optical, though, that's a case unto itself). Good luck! Klaus
