View Full Version : Is MS Dos used on Win ME boot disk?

Hi all

Does anyone know what part of the Win ME OS is used on a boot disk. I know that MSDOS.SYS, IO.SYS and COMMAND.COM are used, and I've used the mem command to see that DOS is using the high memory area. But surely there is a paradox here. If Win ME does'nt use DOS real mode then why are thes files there? Typing the ver command after booting from an ME boot disk gives Windows ME ver 4 point something, so clearly the OS resident in memory does'nt want to bee seen as DOS - but is it! The point i'm trying to make is that the system loaded from an ME boot disk can't be the Win ME OS because that's a 32 bit OS that runs in protected mode. I'm more inclined to beleive that it is DOS albeit with a fancy 32 bit sounding name, and that Microsoft have only included it for making boot disks.

Anyone else have any more info or ideas on this...

Windows Me is built on ancient DOS code but no longer includes the real-mode DOS that let Windows 9x restart in MS-DOS mode or boot to a DOS prompt. A surprising benefit of the change is that DOS windows and full-screen DOS boxes under Windows Me are snappier than in earlier Windows versions. Advanced users, however, will have to cope with Windows Me's inability to load device drivers or memory-resident utilities listed in the Config.sys or Autoexec.bat files used by earlier versions of DOS and Windows. If you want to use memory-resident programs in DOS windows, they must either be launched manually or from a batch file that you create and list in the Properties tab of the MS-DOS Command Prompt shortcut.

Officially, Microsoft says you can boot to the real-mode command prompt only from the Emergency Boot Disk, which may leave too little memory free for running BIOS-flashing and similar programs that run only from the command prompt. Unofficially,you can create a minimal bootable floppy disk by copying Io.sys and Command.com from the WindowsCommandEBD folder to a blank formatted disk.

Go here to get a bootdisk based on DOS for your ME system:

works better too.
