I would not recommend using the utility WinMeDOS.COM with Windows Me. Here's why:

1. I wanted to use Ramdrive to put my swap file into RAM for faster access. To do 
this, I had to modify my boot files with WinMeDOS. It didn't work. Ramdrive allows 
only 32 KILOBYTES (not megabytes) maximum size. This wasn't large enough for my Windows 
Temp directory. Forget the swap file.

2. The changes to my boot files caused problems with startup and shutdown. Sometimes 
startup would hang and I would have to hit reset at least once to get the boot sequence 
to finish. When I would shut down, it would occasionally hang on Rundll32.exe. EVERY 
TIME it would get to the bitmap message "Windows is shutting down" and show a screen 
of vertical orange bars without shutting off the computer. Replacing the modified 
files with WinMe's original files solved the problems.

Some people might have better luck with WinMeDOS than I did, but all I can say is, 
"Caveat emptor." Maybe Microsoft really does know what they are doing.

Don, y'all
