Summary:
The following article discusses how to successfully load and start the
Remote Access Server (RAS) on a LAN Manager version 2.1 enhanced DOS
workstation from two 720K floppy disks. This procedure is primarily
intended for use with older laptop machines with dual 720K floppy disk
drives and no hard drive. This configuration should also run
successfully from a machine with a single floppy disk, although this
will involve some disk swapping.
This configuration requires that LAN Manager 2.1 and RAS be
successfully installed on a DOS workstation prior to copying to dual
720K disks. This must be accomplished by installing an enhanced LAN
Manager 2.1 DOS workstation and the DOS RAS service. Additionally, the
RAS service on the workstation must be correctly configured for the
modem on the machine with the 720K disk drives because the Setup
program for RAS will not be included on these floppy disks.

INSTALLATION INSTRUCTIONS
=========================
To begin the installation, format one 720K floppy disk as a system
disk (format /s) and label it appropriately (for example, RAS
Startup). Format a second floppy disk and label it appropriately (for
example, RAS Work). The following discussion assumes that the LAN
Manager enhanced workstation has been installed to the C:\LANMAN.DOS
directory. If not, make the necessary substitution in the following
discussions.
The files will be copied from the appropriate LAN Manager directory on
the hard disk to the same directory on the appropriate floppy disk.
For example:
copy c:\lanman.dos\comdev.ini a:\lanman.dos\comdev.ini
The format of the directory structure and associated files on the
floppy disk drives is listed below. Copy the listed files from the
appropriate directory on the hard disk drive to the same directory on
the floppy disk drive. It is not necessary to copy the CONFIG.SYS and
AUTOEXEC.BAT files from the hard disk drive because they will need to
be created in a specific format. All unnecessary files have been
removed. The main purpose of these floppy disks is to allow access to
a network via RAS on a machine that does not have a high-density disk
drive or a hard disk. There is sufficient space on each of the disks
to add in necessary DOS commands and any other desired utilities disk
space will allow.

this disk. The second column lists the location of the file from the
hard drive. The LANROOT directory is assumed to be C:\LANMAN.DOS;
substitute as appropriate.

MODIFICATIONS TO SYSTEM FILES
=============================
The CONFIG.SYS file, shown below, resides on disk 1 and is the minimum
configuration required to run RAS and LAN Manager 2.1 from two 720K
disks. Other devices can be added as space permits.
FILES=30
BUFFERS=10
LASTDRIVE=Z
SHELL=A:\COMMAND.COM /P /E:512
DEVICE=A:\LANMAN.DOS\DRIVERS\PROTMAN\PROTMAN.DOS /i:A:\LANMAN.DOS
DEVICE=A:\LANMAN.DOS\DRIVERS\ASYNC\ASYMAC.DOS
Construct the AUTOEXEC.BAT file as follows. It also resides on the
root of disk 1 and represents the minimum configuration needed. Other
features may be added.
@ECHO OFF
PATH A:\;B:\;A:\LANMAN.DOS\NETPROG;
PROMPT $P$G
SET COMSPEC=A:\COMMAND.COM
B:
NET START WORKSTATION
CALL RASLOAD
A:
RASPHONE
B:
Edit the LANMAN.INI file on disk 2 as follows:
1. In the [workstation] section, the lanroot entry should read:
lanroot = A:\LANMAN.DOS
2. In the [services] section, specify the new location of the LAN
Manager services as follows:
chknet = B:\chknet.exe
minses = B:\minses.exe /n
workstation = B:\netwksta.exe
messenger = B:\msrv.exe
netpopup = B:\netpopup.exe
encrypt = B:\encrypt.exe
NOTES
=====
There are several disadvantages of running this particular
configuration. All invocations of RASPHONE must be done from drive A.
All net commands (NET LOGON, NET USE, NET SEND, and so forth) must be
done from drive B. If these commands are run from the incorrect drive,
an error message similar to "unable to open message file xxxxx.msg"
will be displayed. This is not a harmful error; it means only that it
is necessary to switch to the root of the other floppy disk and retry
the command.
If any modification to the configuration of this setup is required
(such as switching modem configurations), it will be necessary to
modify a fully installed DOS LAN Manager enhanced workstation from a
hard disk, and copy the modified files to the appropriate floppy disk.
