The CONFIG.SYS File
The CONFIG.SYS file contains device lines that list the network device
drivers MS-DOS or OS/2 loads when you start your computer. All
LAN Manager device drivers must be listed in the CONFIG.SYS file.
Note
This file may have a different name on your computer—for
example, CONFIG.OS2 for dual-boot systems.
When you use the Setup program to install LAN Manager, you are
asked to identify the network adapter(s) in your computer. The Setup
program uses this information to write lines to CONFIG.SYS that list
the device drivers associated with those cards. Device lines take the
following form:
device=[drive:][path]filename [options] ifs=[drive:][path]filename
[options]
where
device
Signifies a device driver to be loaded.
drive: and path
Specifies the drive letter and directory containing the network device
driver software.
filename
Is the complete filename (including extension) of the network device
driver.
options
Varies depending on the particular driver installed. For example,
options might include a shared memory address, an interrupt level, or
a path.
ifs
Signifies an installable file system (IFS) to be loaded.
If you manually install LAN Manager drivers, be sure they are listed in
CONFIG.SYS in the following order:
1. The Protocol Manager driver, PROTMAN.DOS or PROTMAN.OS2.
Do not install this driver if you use only monolithic network device
drivers. The CONFIG.SYS line that loads PROTMAN requires a /i:
option to specify the directory containing the PROTOCOL.INI file.
