I just create a Windows 98 boot disk with Windows Millenium and reboot when I want pure MS-DOS with real mode only for low level tests. I use RAWRITE under either 98 or Me to set the disk, or another USB stick, hard disk or computer to exchange between 98 and Me. MS-DOS 8 will probably always have something like V86 enabled. I just install Windows 98 and Millenium side by side with 2 BAT scripts to change between them, because there are some programs to plainly refuse to run under Windows Millenium when they detect that the Windows version number doesn't match Windows 98 or SE. Given that MS-DOS 8 is incapable of Real Mode, you could make a disk image with a Windows 98 boot disk, or a Windows 98 DOS bootable USB, CD-ROM, or use a second computer. Then you could install Windows 98 and Windows Millenium together, and two BAT scripts that run/enable either 98 or Me, and rename themselves to prevent renaming WINDOWS and Program Files for each OS, they could be WinME.bat or Win98.bat. If you boot to DOS with a Windows 98 boot disk and have Me and 98, you have the full and most modern 9x system, you can use Windows 98 to run programs that detect Me and refuse to run and to have full DOS.
