This information is indirectly cross referenced & related to the following web Link
http://reboot.pro/to...rough-vmm32vxd/
However this is in relation to the previous version of Dos namely Dos-7 NOT Dos-8.

If you are of German persuasion here is the original German version website (Dos7) :
http://www.winfaq.de...p?h=tip1826.htm

& more recently this one for the English translated transcript of a German website above (Dos7):
https://www-winfaq-d...en&_x_tr_pto=sc

This resurrected article comes courtesy originally of an individual called Mike Risch, a talented individual who is the architect of Mindows which basically is a cut down version of Windows 98SE, as a side note I think the intention of Mindows was to use it for repairs etc. I believe there may be a section on RebootPro devoted to or hosting Mindows not a 100% sure.

Anyhow sliding on, the other day I was sifting through an old hard drive & came across an old article that Mikes old website discussed & I thought it would be interesting to combine the content of his old web-site (Mindows/XDOS) details with Windows ME-Dos  (or ME Dos-8 if you prefer) setup in a 32bit Dpmi Dos that fits onto a floppy disk.

NOTE - A lot of the shortcomings of M$ ME Dos-8 have been overcome on a Russian website which I will call or refer to as (tongue in cheek) naughty Dos (I will not be posting the link as it may contravene rebootpro rules) as this version of Dos8 will be considered dubious, because it distributes ME-Dos files, however in their defense, the way they have achieved their little project may not be a problem as long as individuals out there on the www have their own copy of Windows ME/XP (XP for what I would call the jaclaz file-set)  tucked away somewhere? My hope is this topic is not overly controversial? Basically I am not trying to subtract anything from naughty dos rather compliment their endeavors.

Anyway here are the details I downloaded many years ago as it might be useful to others wishing to create a Mini-ME (1.44mb) version of a 32bit variant of DOS (A fun Project if you like!). Mikes original project is as follows:

 

By the by, if Mike is around he may be able to shed some light or even fill in the blanks if I fail to explain the construction details, here's the info anyway:
Mikes project was called XDOS & outlined below are transcripts taken from his previous website as-was-in its day, a snapshot:

 

XDos Files
Last updated July 14, 2002

I have succeeded in loading the 32-bit dpmi dos from Windows ME from a single floppy. I am calling this XDos (eXtended Dos). Not sure about the utility of something like this, but it appears that this boot floppy is not machine-specific. Wish I could distribute this floppy, but obviously Microsoft would not be pleased with an effort such as this :0). The neat part is that the files just barely fit onto a single floppy, vmm32.vxd alone taking up a whopping 1,012,656 bytes! (My thoughts - Other files could be added with disk spanning or larger image file cannot remember if 2.88Mbs had flaky problems in booting? food 4 Thought)

Unfortunately, ME real dos requires a patch in order to allow booting to C:\> rather than directly to Windows. This patch can be obtained at : "Is provided in the link below XDOS by MRisch.zip"

The following link provides a dpmi application to test your XDos installation : Testfloat.exe "Provided in the link below XDOS by MRisch.zip" (Not sure why this is needed for but is provided for historical reasons, if Mike is around he may be able to explain possibly, I'm guessing this has something to prove if you are in a 32bit environment???)

These details are in respect of the directory layout:

The command sys.com will not work with ME Dos (MSDos8). To make a bootable disk, you will have to format with format a: /s under another dos version, then delete all these files, and finally copy the root ME files. Copy io.sys first, as it needs to be at the beginning of the disk. also here again you could possibly interchange command.com with 4dos.com but not sure whether this would breach the 1.44Mb boundary?

I think if some of the amended updated files from the Russian version of  ME-naughty-Dos e.g. IO.SYS or files from Jaclaz's diskcopy from XP  Posted Jan 1 2008 : "XPBTDSK.EXE ... a console application to extract the image from diskcopy.dll" http://jacevedo.phst...fo/getbtdsk.zipetc ("from naughty DOS website ") are interchanged with the folder/filelist above it could be a usable updated alternative (please feel free to post your thoughts reservations & considerations). Please find enclosed a zip file below some of the pre-built files as outined in the script info above to aid proceedings if you wish to undertake this little project. Maybe a script/batch file could be constructed to build such a varient?

One thing I have noticed that is different between the XDOS & the other types illustrated is that XDos does not seem to be bundled with a registry, the others have either a mini registry or full system.dat/user.dat & that would not fit on a floppy disk. However maybe I'm getting confused & we are talking about two different animals here?

Reference details for some useful utils taken from wink wink naughty ME-dos website:

  • IO8DCOMP.ZIP
  • http://jacevedo.phst...fo/getbtdsk.zip= getbtdsk.zip (aka Jaclaz Wonko etc)
  • cabextract 1.2 © 2000-2006 Stuart Caie a program that un-archives files in the Microsoft cabinet file format (.cab) or any binary file which contains an embedded cabinet file = cabex12b.zip
  • Dariusz Stanislawek   DS File Ops Kit dsfok.zip
  • Gilles Vollant Extract extrac21.zip

Maybe someone will want to run with this, I have enclosed some of the utils obtained from the naughty dos website to aid and assist in endeavors. When I get time I will post the old PC-Welt PCW9912 Bat File for historical closure as an edit to Dos7 32BitDos variant with applicable details of how to install.
One further thought if I was being correct in issuing credit for the Dos7 32Bit Dos it should go to an individual called Bernd Blaauw from the old CD-forum he posted the first info on 32Bit dos (That I know of) & PC-Welt developed it further into an installer PCW991232BD!.exe (Please correct me if I am wrong?)

 

& lastly - as always, get into the habit of scanning these attached files for virus's, it's just good practice!

 

NJoy & Best Regards,

I
