SUMMARY
LAN Manager version 2.1 with the Remote Access Service (RAS) is primarily intended to run on machines with a hard disk drive. However, it is possible to create a high-density, bootable LAN Manager 2.1 Enhanced RAS MS-DOS workstation floppy disk. The following steps describe the procedures and directory structures required.



INSTALLATION STEPS
Create a bootable high-density floppy disk (FORMAT A: /S), using either a 3.5-inch (1.44 MB) or 5.25-inch (1.2 MB) disk. Once the disk is formatted, copy the files listed below to the same directory on the floppy disk. The tree structure of this disk is as follows: A:\ COMMAND COM CONFIG  SYS AUTOEXEC BAT

A:\LANMAN.DOS\ LANMAN  INI MODEMS  INF RASPHONE MSG RASDIAL MSG RASHELP MSG COMDEV  INI PHONE   INF PROTOCOL INI

A:\LANMAN.DOS\NETPROG\ CHKNET  EXE MINSES  EXE NETBIND COM LOAD    COM OSO001  MSG NET     MSG NET     HLP NET     EXE NETWKSTA EXE RASLOAD BAT RASPHONE EXE VCOMMIOD EXE WANTSR  EXE

A:\LANMAN.DOS\DRIVERS\PROTMAN\ PRO    MSG PROTMAN DOS PROTMAN EXE

A:\LANMAN.DOS\DRIVERS\PROTOCOL\ASYBEUI\ ASYBEUI EXE

A:\LANMAN.DOS\DRIVERS\ASYNC\ ASYMAC DOS

A:\LANMAN.DOS\SERVICES\ MSRV    EXE ENCRYPT EXE NETPOPUP EXE

A:\LANMAN.DOS\LOGS\ MESSAGES LOG In all cases, the files listed are copied from the hard disk directory to the identical directory on drive A.

There is an alternative to copying the files directly from the hard disk to the floppy disk that involves deleting files from the hard disk installation before copying to the floppy disk. In this circumstance, all files in the LAN Manager tree not listed in the above description are deleted, leaving only the structure as listed. At that point, XCOPY the structure to a formatted system floppy disk (note: include the subdirectory switch with XCOPY). For example:

xcopy c:\lanman.dos a:\lanman.dos /s

The disadvantage of the installation technique just described is that it will leave the LAN Manager tree on the hard disk workstation without all of the functionality of the original installation.

MODIFICATIONS TO SYSTEM FILES
Once the files have been copied to the appropriate directories, make the following modification to the lanroot entry in the [workstation] section of LANMAN.INI:   lanroot = A:\LANMAN.DOS Modify CONFIG.SYS to update the LAN Manager driver devices to look to drive A, as well as set the location of the shell to A:\. For example:   FILES= 30 BUFFERS=10 SHELL=A:\COMMAND.COM /P /e:256 DEVICE=A:\LANMAN.DOS\DRIVERS\PROTMAN\PROTMAN.DOS /i:A:\LANMAN.DOS DEVICE=A:\LANMAN.DOS\DRIVERS\ASYNC\ASYMAC.DOS It is also necessary to modify AUTOEXEC.BAT by setting the comspec, path, and LAN Manager path extension to point to drive A. It is also possible to autostart RASPHONE by including it at the end of the AUTOEXEC.BAT file, after calling RASLOAD. For example: @ECHO OFF PROMPT $P$G SET COMSPEC=A:\COMMAND.COM PATH A:\; REM ====== LANMAN 2.1 === DO NOT MODIFY BETWEEN THESE LINES ===== LANMAN 2. === SET PATH=A:\LANMAN.DOS\NETPROG;%PATH% NET START WORKSTATION CALL RASLOAD REM ====== LANMAN 2.1 === DO NOT MODIFY BETWEEN THESE LINES ===== LANMAN 2. === Note: The above are minimal configurations. Options can be added at any time, and are limited only by available disk space.

OPTIONS
If the modem is sufficiently fast, it is possible to locate the majority of the MS-DOS and network executables on the network, and allow them to be accessed across the modem connection. Please note that even with the fastest of modems, workstation performance will be seriously degraded. The steps necessary for creating this situation include the following:

 Create a share on the server that contains MS-DOS and a full LAN Manager 2.1 Enhanced MS-DOS RAS workstation.  Create a batch file, called LOGON.BAT, to log on to the server. The usage is identical to the NET LOGON command currently used. The batch file (LOGON.BAT) will resemble the following:      @ECHO OFF REM Logon to server and transfer control to the LM share net logon %1 %2 /y net use A: \\ \ REM This connects us to the LM share  The structure of the directories on this share should be identical to that listed above. Access to the boot floppy will be disallowed. However, on a machine with only one floppy disk drive, the boot floppy disk can still be accessed via the MS-DOS drive mapping capabilities. Therefore, the disk drive can be referenced by accessing B:. MS-DOS will map this to the one physical floppy disk, allowing access.</li>  Similarly, a batch file for logging off must be constructed. It should resemble the following: <pre class="fixed_text">     @ECHO OFF REM Logoff from server B:     NET LOGOFF /Y A: Using this method may result in some harmless error messages of missing batch files and possibly a missing NET.MSG at log off time. This is to be expected and the messages can be ignored. </li></ul>

Given this configuration, it is possible to create a bootable LAN Manager 2.1 Enhanced MS-DOS RAS floppy disk. The important points to note are that it is required to first install the configuration to a workstation with a hard disk. The installation must be made for the hardware that is to be booted from the floppy disk, regardless of what is on the hard disked workstation. There should be sufficient room on the floppy disk for the most commonly used MS-DOS utilities.
