You are correct that the AppleShare PC 2.0 installer can install from A: to
B:--even when B: is just a logical drive. DOS prompts for each disk as it is
needed. Unfortunately, because of the installer program's design, this might
require swapping disks as many as 100 times--even for print services alone.
This means that we do not recommend installing AppleShare PC 2.0 using a system
that has only one floppy drive and no a hard disk. Booting such a system with
already installed disks works fine. However, unless you enjoy swapping disks,
don't try to install on it.
As a side note, the installer is actually an executable file, not a batch file.
You can write a batch file to do the install by using the xcopy command on
groups of files. This shortens the install process a great deal and allows
installing with a single drive PC. Of course, it also requires manual
preparation of AUTOEXEC.BAT and NET.CFG and selection of the proper REDIR file,
depending on what version of DOS is being used.
