I would have replied by mail, but out mail seems to hate me.  I
haven't used version 2.x in awhile, but I would expect it would run
like 3.x in this case.

The DOS manual points out that there are 2 different commands having
to do with the shell.  One, in the CONFIG.SYS, is SHELL=.  This
command is used to tell DOS which shell to load (I have written my own
and like to have it loaded by default).  Anyway, the manual says to be
sure you remember that this command does NOT tell DOS to reload from
wherever you told it to load from.  Instead, DOS uses the environment
variable COMSPEC.  I have this set in my AUTOEXEC.BAT file.  Set it
like this:

SET COMSPEC=C:\COMMAND.COM

This definitely works on 3.x and I'm pretty sure it does on 2.x, since
my friend with a Tandy 1000 (DOS 2.11) has his run from C:.

Hope this helps, and I'm sorry if I used over-simplistic language.
