My version of MS-DOS 6.30 is now largely complete, and is in testing. This version is used to undertake tests with Windows 9x, and what 7.10 might look like.
This version of DOS started life as an extension of the 'oldmsdos' files on the Windows 9x cdroms. With a little further extension, it became a full blown DOS version. Currently, the layout is on two diskettes, one that has MS-DOS and one that has the utilities from dos 4/5/6 on it.
No fancy installer, but we use a compiled batch file to copy a config.sys and autoexec.bat onto the hard drive.
The idea of using a non-generic DOS is educational, and thus as an educational facility, escapes the copyright law. What happens is that when you co-mix files from this DOS and a real DOS, like ms-dos or pc-dos, it should easily pick which DOS is which. In this way, it's a clearer indication of what various programs are doing.
The first diskette contains the files of ms-dos 6.30, being patched versions of 6.22, along with a number of files from the Win95 OPK, and edit-v2. Most of this is packed with compress v 1 (KWAJ), but you simply need to prepare a hard drive, and then run 'install' from the diskette.
The second diskette contains various files from msdos 4 to 6, (access, dosshell, extract, qbasic 1.1, manager (dos 3 shell), msd 2.12 (ie the 3.01 on the internet), and a smattering of small files. The help file is the version on this forum, with some updates. This is identical for any of the prepared MS-DOS versions, and even runs without mods for PC-DOS.
A corresponding PC-DOS disk exists, with acalc, basica, e editor 3.13, dosshell 7, rexx, t (tiny edit for DOS), unpack2, and the PC-DOS 7 help system. The rexx utilities might be placed in a zip-exe file, being so tiny.
For those curious, I am also putting a NGDOS, which is alternate freeware (largely avoiding freedos), of utilities that replicate functionality, with additions. An example is Paul Houle's excellent 'doskey' 2.0 (dos) and 2.5 (w9x), which are suited for running under DOS6 and less, against Windows 9x,
