******************************* Introduction **********************************
The Symbios SYM53C885 Ethernet device driver is written to the Network Driver
Interface Specification, Version 2.01. This is the native interface to all of
the networking features designed into the IBM OS\2 operating system,
including TCP/IP. OS/2 also provides the necessary software components to
interface the Symbios SYM53C885 Ethernet device driver to popular server
technologies, including Novell and Microsoft server and client platforms.
* * * * * * * * * * * Features * * * * * * * * * * * * *
o Supports MII Ethernet Interface at 10 and 100 megabit speeds
o Supports DMA (Direct Memory Access) for high network speed and throughput
o Supports Half or Full duplex Ethernet connections
* * * * * * * * * * * Description * * * * * * * * * * * *
The Symbios Ethernet solution consists of the device driver, ND885X.OS2, and
the network interface file, ND885X.NIF. This driver enables OS/2 to connect to
any Ethernet LAN using a 10 or 100 megabit Ethernet connection at either half
or full duplex.
******************* Installing Your SYM53C885 OS/2 Driver *********************
The successful installation of the Symbios SYM53C885 Ethernet device driver
requires some basic knowledge of the OS/2 DeskTop environment. It also requires
that the person doing the installation has network administrator capabilities
on the machine on which the Symbios SYM53C885 Ethernet adapter is being installed.
No information is provided concerning TCP/IP addressing, or Novell or Microsoft
server or client setup or connection information. Please refer to the IBM OS/2
installation guide for any questions which you might have regarding these issues.
First you need the Symbios Ethernet driver diskette, which has the files
ND885X.OS2 and ND885X.NIF on it. If these files are not in the root directory
of this diskette, determine where on the disk they are located and write down
the path information for use at a later time. If they are in the root area of
the diskette, proceed to the installation which matches your system requirements.
* * * * Installing the Symbios SYM53C885 Ethernet device driver * * * *
on a computer which is currently running OS/2.
1. Double click on the OS/2 System Icon from the OS/2 desktop.
2. Double click on the System Setup Icon in the OS/2 System-Icon View.
3. Double click on the MPTS Network Adapters and Protocol Services Icon
in the System Setup-Icon View.
4. Click on Configure in the Multi-Protocol Transport Services window.
5. Select LAN adapters and protocols, and click on configure in the Configure
window.
6. Click on Other adapters in the Adapter and Protocol Configuration window,
under the Network Adapters area.
7. Enter the path to the files, ND885X.OS2 and ND885X.NIF, in the Copy
Additional Network Adapter Drivers window. You recorded these files from
the Symbios Ethernet driver diskette earlier in this section.
8. After entering the path, or if the files are in the root directory of the
diskette, place the diskette in the A: drive and click OK.
8. Once the files are copied from the diskette, the Adapter and Protocol
configuration window returns. Scroll through the list of Network Adapters
and select the Symbios SYM53C885 Fast Ethernet Adapter (ND885X.OS2) and
click ADD to install the driver.
9. Now install and configure the protocols that match your environment using
the IBM OS/2 documentation, and exit from the MPTS program.
10. Reboot your computer in order for the change to take effect.

during the installation of OS/2
1. Using the IBM OS/2 documentation, begin the installation of OS/2.
2. During the networking installation section of the OS/2 install, use the
Symbios Ethernet driver diskette when prompted for the network adapter
driver. Make sure to provide the correct path information for the files,
ND885X.OS2 and ND885X.NIF, which you recorded from the Symbios Ethernet
driver diskette earlier in this section.
3. Install and configure the protocols which match your environment using
the IBM OS/2 documentation.
*************************** Configurable Driver Options **********************
The Symbios SYM53C885 Ethernet device driver, ND885X.OS2 has four configuration
parameters. The configuration parameters available are: Media Speed, Duplex Mode,
Ethernet Mode, and TPPMD ciphering. A short description of each option is
provided, with default values, functions, and any impact its use may have on
your system. The options described below are modified by running the OS/2 MPTS
program described in the Installing Your SYM53C885 OS/2 Driver.
Note: The SYM53C885 uses a process called auto-negotiation to determine
network settings. If your network hardware does not support auto-
negotiation, the MEDIA SPEED, ETHERNET MODE, and DUPLEX MODE
options must be manually set to match your existing network
configuration. Ask your network administrator for instructions if you
have difficulty connecting to your network.
To change any of the following settings, first begin the OS/2 MPTS program by
the method which is defined in the Installing Your SYM53C885 OS/2 Driver
section of this document.
1. When you are at the Adapter and Protocol Configuration window, select the
Symbios SYM53C885 Fast Ethernet Adapter (ND885X.OS2) in the Current
Configuration section and click EDIT.
"The Parameters For the Symbios SYM53C885 Fast Ethernet Adapter (ND885X.OS2)"
window displays each of the Configuration options.
2. To make a change, enter the new value inside the corresponding window, and
click on the OK button when all selections have been made.
In the event an incorrect parameter was entered, the OS/2 MPTS program will
prompt you with a list of the acceptable choices.
* * * Changes to the Media Speed Option * * *
Use this option to set the required number of data bits that can be transmitted
across the wire per second (network speed) for your network setup. The default
value is Auto, which enables the auto-negotiation feature of the Symbios
SYM53C885 Ethernet device driver.
Note: This should only be changed if your network hardware does not support
auto-negotiation.
Valid options: 10, 100, Auto
Function: Specify the network speed to use.
Possible Impact: If specified incorrectly, networking may not work.
* * * Changes to the Duplex Mode Option * * *
This option provides the ability to specify duplex support for your network.
Half duplex allows the network to either transmit or receive data at any given
time, while full duplex allows simultaneous transmitting and receiving of data
at any given time. The default value is Auto, which enables the auto-negotiation
feature of the Symbios SYM53C885 Ethernet device driver.
Note: This should only be changed if your network hardware does not support
auto-negotiation.
Valid options: Full, Half, Auto
Function: Specify the duplex mode to use.
Possible Impact: If specified incorrectly, networking may not work.
Note: The Duplex Mode and Media Speed must match the network settings. For
example, if the network is 10 megabits per second at half duplex, then
the adapter must match this setup in order for data to be transmitted
or received.
* * * Changes to ETHERNET MODE option * * *
This option provides the ability to set which media interface to use. The default
value is Auto. This enables the auto-negotiation feature of the Symbios SYM53C885
Ethernet device driver.
Note: This should only be changed if your network hardware does not support
auto-negotiation.
Valid options: Auto, MII, TPPMD
Function: Set media interface
Note: Currently, the SYM53C885 supports only the MII interface.
The TPPMD option can only operate when a TPPMD transceiver is attached.
Possible Impact: If specified incorrectly, networking may not work.
* * * Changes to the TPPMD Cipher Option * * *
This option provides the ability to turn off the ciphering function of the
TP-PMD media interface. Currently, the SYM53C885 supports only the MII
interface, so changes to the TPPMD cipher option will not affect the Symbios
SYM53C885 Ethernet device driver.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
