     Please help me.
     I have developed a fake UNIX console with DJGPP and I want it to
run from a big ramdrive (ramdrive.sys as part of DOS) and I would
like to run a DJGPP executeable from the virtual disk. It is quite
easy to run on the hard drive with CWSDPMI, but on the ramdisk 
the DPMI server does not appear to work.

    Is there any other way to run a 32-bit application after booting
from a floppy and copying the stuff to RAM where it will be ungzipped.
In testing this I also had a minor problem with gzip. DJGPP binaries
compress nicely with gzip, and I have written a 16 bit program
to piggyback both gzip and a compressed 32-bit application and then
a .tgz file. This works nicely in a windows environment, but sometimes
the compressed binary cannot be decompressed in a DOS environment.

   The piggyback system can be seen on my website.
