China DOS Union

I use WINME, and I'm very satisfied with its MS-DOS 8.0, but DOS can only run under the WINDOWS environment, not pure DOS. It can't be like WIN98, where you can just modify MSDOS.SYS
Who can make WINME unable to start, so that it starts MS-DOS 8.0 instead, by deleting a few important files?

You can download a special patch, or: replace a file in the SYSTEM folder called something starting with R with C:\COMMAND.COM, then it can start MS-DOS 8.0.
