Wancho") Newsgroups: comp.sys.misc Subject: SYS and DOS 3.20-3.21 Message-ID: Date: 16 Jun 89 02:58:00 GMT Sender: daemon@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 9 The SYS command generally does NOT work when moving up from a lower numbered DOS to a higher one. Well, the command works, but the result is not what you want, namely to have the first two files be those system files. This is because each progressively newer version is larger than any previous version, and the BIOS can't handle a fragmented DOS, in general. (Zenith's MSDOS 3.3+ does, but there are other problems, and that's another story.) --Frank
