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 !

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 : ME Dos patch

The following link provides a dpmi application to test your XDos installation : Testfloat.exe

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.
