The only machines DOS runs on are PCs and compatibles. | UNIX implemented on these machines would be just as vulnerable as DOS. | The most obvious weaknesses of DOS are unimportant compared to the fact | that the hardware itself has no protection mechanisms. True, but only of the 8088 (original XT) machines. The AT and 386 machines run UNIX in protected mode, and have as much hardware protection as a VAX. - --- bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) "The world is filled with fools.
