                             PC-NFS Directory


This directory and the directories below it contain run-time drivers for
using your AST local area network adapter within a Sun Microsystems PC-NFS
environment.  Please consult your AST LAN Adapter Installation Guide for
instructions on configuring the adapter, and the documentation that came
with the PC-NFS software for instructions on installing PC-NFS.

Install your AST-Ethernet or AST-EtherNode adapter in your PC.  During the
configuration portion of the installation, make a note of the following
information (it will be used during the installation of PC-NFS):

1.   I/O Address - This is needed for the command line in the CONFIG.SYS
     file which is used to load the driver at boot time.

2.   Node Address - This is needed by the System Administrator of the
     network you will be using.

The CONFIG.SYS file on your boot disk drive needs to have the following
line added to it to allow the AST-Ethernet or AST-EtherNode PC-NFS device
driver to be loaded at boot-time:

     DEVICE = [d:][path]netdrvr.SYS /Pport

     Where:

           d = The disk drive specifier.

        path = The pathname of the directory which
               contains the device driver.

     netdrvr = The name of the network device driver.
               ENETNFS for the AST-Ethernet adapter
               ENODENFS for the AST-EtherNode adapter.

        port = The I/O address of the adapter.

     For Example:

     DEVICE = C:\NFS\ENETNFS.SYS /P380

     The above line would cause the driver for the AST-Ethernet adapter
     (ENETNFS.SYS) to be loaded from the NFS subdirectory on drive C.  The
     adapter is set to use port 380.

The following subdirectories contain the network device drivers for the
AST-Ethernet (ENETNFS.SYS) or AST-EtherNode (ENODENFS.SYS) adapters:

          Adapter                         AST Diskette Directory
          -------                         ----------------------
          AST-Ethernet                    \PC-NFS\ETHERNET
          AST-EtherNode                   \PC-NFS\ETHRNODE

To add the appropriate network device driver line to your CONFIG.SYS file,
first run the installation program included with the PC-NFS software.  If
you are installing PC-NFS version 3.0 or greater, the install driver menu
contains an option marked "Other."  If you choose this option, the program
prompts you for the line to add to the CONFIG.SYS file.

Previous versions of PC-NFS do not have the option which allows you to
install drivers other than those included with the software.  Therefore, to

load the driver for your AST LAN adapter, you must perform the following
steps:

1.   Run the PC-NFS installation program.  When you are prompted for a
     device driver, select one of the drivers included with the software.
     Continue with the installation process until it is complete.

2.   Use a text editor, such as EDLIN, to modify the CONFIG.SYS file so
     that it specifies the device driver for the appropriate AST LAN
     adapter rather than the device driver chosen in step one above.
