Jerome Fine replies:

I realize that you are probably not running Windows 98 SE,
but I have a Pentium III running Windows 98 SE (because I
use E11 to run PDP-11 programs and this is the ONLY
operating system which works) and use GHOST for backups.

I also have an AHA2940 as well and I see that GHOST has
an option to make exact copies of ANYTHING! So you
don't even need to have a directory that GHOST recognizes.

Just thought this might be helpful????

Sincerely yours,

Jerome Fine
