Being I'd think that would be a horrible disadvantage on the PC platform. Folks are going to want to be able to boot off of SCSSI devices, CDROM drives, Floppies, ZIP disks, LS-120's, PCMCIA drives, firewire drives, and whatever else they may invent next week. Its OK to not support all that stuff at first, but it should be doable. --- T.E.D. homepage - http://www.telepath.com/dennison/Ted/TED.html home email - mailto:dennison@telepath.com
