You boot the Mac OS, run sash and instead of launching unix, you run the standalone fsck. The standalone environment allows you to run many of the common utilities (dd, cp, mv, rm, ed, fsck, fsdb, and more) It's not a bootable floppy based unix, but it does solve most of the problems. >-- >Jim Rosenberg pitt >Oglevee Computer Systems >--!amanue!oglvee!jr >151 Oglevee Lane cgh >Connellsville, PA 15425 #include Opinions: MINE, ALL MINE!
