Well, I did experiment and came out with the following problems:
1.  If I specify SHELL=D:\PATH\BASH.EXE in CONFIG.SYS,  DOS 6.22 will
complain about "No DPMI" and then "Your command processor is no good".  It
falls back to COMMAND.COM .
2.  If I fire up bash from the DOS command line, it will eat up a big
chunck of my DOS memory (409K -> 312K).  But everything else works fine.
3.  I don't have any DPMI server that I can (or know how to) load before
the SHELL= command in CONFIG.SYS .

Help!
