files as harddrives?

[Bryan Stillwell <bryan@bokeoa.com>]

I have a dos program that I'm trying to get to work, but I haven't found
a way to get a file under linux to behave as a drive under dosemu.  For
the dos program to work, it must believe that the filesystem image under
linux is a drive in the dosemu bios.  The old wholedisk option looks
like it would work, but I'm using version 1.0.2.1-7 (from Debian stable)
and it appears to not be available.

The dos program I want to get working is called ltools, which is a set
of utilities to read linux filesystems.  The web page can be found here:

I'm trying to automate a portion of our testing process that requires
generating signatures of files read off an ext2 filesystem that are
located on a compact flash.  The signature generating program is run
after ltools is used to copy the files off the compact flash, and it is
also a dos program.  Since this is a verification test, I must maintain
the process as close as possible, so things like copying the files to
the dos directory beforehand won't work.

Anyone here have a filesystem image working as a harddrive under dosemu
with the latest stable version?  I've got it mostly working under bochs,
but it's slow and I would rather use dosemu if I can.

Thanks,
Bryan
