When an NDIS Application Already Exists
To set DOS system files when an NDIS network application already exists, you need to
understand more about how an NDIS application is setup. The following files must be
installed for an NDIS application.
PROTMAN.xxx NDIS Protocol Manager Driver. Extension varies. GE Fanuc
uses PROTMAN.DOS
(Network Card Driver) Provided by PC network card manufacturer. Name varies.
PROTOCOL.INI File listing each driver and operating parameters for each.
For GE Fanuc applications, the LLC driver, GEFNDIS.DOS, must also be installed. For
the GSM, all these files, and some others, are located in the GEFNDIS directory. But, if
an NDIS application has been installed previously, other versions of the files described
above, except for GEFNDIS.DOS, will already have been placed in another location.
The steps below will explain what to do with these NDIS files to ensure proper network
GSM operation.
1. To set up your PC so the GSM software and another NDIS network application can
both run, you must ensure that your CONFIG.SYS file and AUTOEXEC.BAT file
contain certain commands. Sample files showing the commands needed when the
GSM is the only application have been created for you during the installation
procedure. These sample files are named CONFIG.GSM and AUTOEXEC.GSM and
are located in the GSM directory. Sample contents are shown in Appendix D. Note
that the content is different for different PC network cards.
Since you are adding the GSM when a Network application already exists, some of
these commands may already exist, so you will not need to add all of these com-
mands. Edit your CONFIG.SYS and AUTOEXEC.BAT as explained below.
2. CONFIG.SYS Include all entries from CONFIG.GSM except the following command.
device=\gefndis\protman.dos /i:\gefndis
The CONFIG.SYS file will already have a valid Protocol Manager (protman.xxx) de-
vice definition from the existing network application, and need not be changed.
This file will also already have one or more PC network card device definitions from
the existing network application. If a valid definition exists for the PC network card
selected for the Network GSM, that definition need not be changed.
3. AUTOEXEC.BAT Include the SET GSMCFG command in this file, but not the
NETBIND command:
set cfiles = C:\GSM\CFILES (assuming default directory)
rem Bind NDIS drivers
rem \gefndis\netbind
The NETBIND command is a call to an NDIS driver binding utility. Since an NDIS ap-
plication already exists, that application must have a call which does the same thing
although it may not be obvious by looking at AUTOEXEC.BAT. When the PC is
started, binding must occur only once.
If installing the GSM software on a PC with a monochrome monitor, add the
following command to the AUTOEXEC.BAT file:
MODE CO80
