Oh, yeah.  I could try that.  I could boot an old DOS 6.2 or whatever 
and try CTRL-ALT-DELETE.  I think that is what you mean.  I don't 
remember that actual command, although I'm sure there's a lot of 
third-party reboot commands...  Some of which I'd like to see in the 
assembler code, myself.  I'll just bet someone has an old MS-DOS BASIC 
program or assembler written in C, Pascal, or something, which could do 
a warm or cold reset.
