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!
