                                                  or

    Can HIMEM.SYS be disabled in Windows ME’s IO.SYS?

          20 50 04 70  ==>> 20 FF FF 70
          C3 1E 66 50 ==>>  C3 CB 66 50

         XMS memory with his  patch disabled but HMA is available and DOS=High

          Another way to load the emm386.exe driver is to use the io8emmok.sys driver by Dr. Pufeng Du.
       
Though this driver does not disable or remove the built-in XMS driver, it converts it to a normal-behaved.
       
It does not require you to decompress Windows Me's IO.SYS.
 

 

 

 

Microsoft Windows Millenium Startup Menu
========================================

 1. Normal
 2. Logged (\BOOTLOG.TXT)
 3. Safe mode
 4. Step-by-step confirmation
 5. Command prompt only
 6. Safe mode command prompt only 


 Enter a choose 1.

 

 

F5=Safe mode Shift+F5=Command prompt Shift+F8=Step-by-step confirmation[N]

 

 

Restart your computer. Press and hold down CTRL until the  Startup Menu appears. This menu appears only   from the floppy image Windows ME OEM Bootable CD IO.SYS.

 

The previous version of MS-DOS does not appear in the boot menu, but io.sys of MS-DOS 8.00 can boot MS-DOS 6.22 as well as io.sys MS-DOS 7.10 on Windows 98SE(kb 121963). Copy the renamed MS-DOS 6.22 system files io.dos, msdos.dos, command.dos to the root folder of the FAT16/FAT12 formatted boot media (USB Flash, real floppy or boot image).
Add the following line to the [Options] section of the file winboot.ini or msdos.sys, if the line does not already exist:
BootMenu=1
BootMulti=1
BootWin=0

Now  you have Dual-Booting MS-DOS 6.22 - Normal(Enter)  and MS-DOS 8.00 - Command prompt(Shift-F5).

 

Russian programmer  fps 2001-07-30  posted: And in WinME it appears is normal DOS :

"It is not necessary any and patches.
MS about all took care itself, but from users it far away hid
We unpack c distributive CD WinME:
\Tools\NetTools\FAC\cbs.dta\winboot.sys
We replace with it C:\IO.sys
\Tools\NetTools\FAC\ltools.dta\command.com
We replace with it C:\command.com and C: \% windir %\command.com
All!
"Command Prompt Only" is present, Autoexec+Config.sys Are processed"

No cracks and patches.
The following files are only on the Windows Me OEM bootable CD - OEM Preinstallation Kit (OPK) for Windows Millennium
Tools\NetTools\FAC\cbs.dta\winboot.sys (118784)
Tools\NetTools\FAC\ltools.dta\command.com (92992)
 

MaxEd May 18, 2003 But there is a MICROSOFT way to get Real DOS-Mode in ME. ME distribution should contain this files:
\Tools\NetTools\FAC\cbs.dta
\Tools\NetTools\FAC\ltools.dta
which are CAB archives. One of them contains io.sys and other - command.com with MS Real DOS-Mode support.

This command.com no have Strange Instructions Built Into COMMAND.COM as noted in  the article by Micho Durdevich RIPLing Windows Millennium Edition From OS/2 Warp Server 
Appendix A: Enabling Real-Mode DOS Support in Windows Millennium Edition "Our main idea is to replace the file VMM32.VXD by the appropriate command interpreter. The simplest solution would be to use the standard COMMAND.COM. However, a slight technical problem appears here, because of a funny mistake in the standard command interpreter COMMAND.COM  Appendix B: Weird Changes in Design of Windows Millennium
If you copy any normal DOS executable over VMM32.VXD, it should start without problems, as a part of WinME "boot". The only ME-runnable program I know that does not start properly is the command interpreter COMMAND.COM

 WARNING: MS-DOS Does Not Properly Process Hard Disk Hardware Errors(kb 311561). Microsoft updated ms-dos kernel files both version 7.10 & 8.0

Microsoft REMOVED the display of the Startup Menu from Windows ME & MS-DOS 8.0 startup disk from Windows XP , Vista, Seven.
