Automatic Installation

	This driver supports the automatic installation procedure defined
	by the IBM LAN Adapter and Protocol Support (LAPS) module. LAPS is
	provided by IBM with the following services:

		IBM OS/2 Extended Services 1.0
		IBM OS/2 LAN Server 2.0
		IBM OS/2 LAN Requester 2.0

Manual Installation

     1. Copy the driver RTR16NDS.OS2, and the message file RTR16NDS.MSG
        from the installation diskette to the desired fixed disk
        drive and directory.

	NOTE: If you are using an FPA based adapter, copy the file RTR16FPA.COD
	      from the installation diskette's DIAGS directory to the ROOT
	      directory on your LAN Server system drive.  When the driver
	      loads, the message "Utilizing FPA microcode" will be displayed if
	      the RTR16FPA.COD file was found and an FPA based adapter is being
	      used. If the RTR16FPA.COD file was not found or the adapter is
	      non-FPA based, the message "Utilizing MAC microcode" will be
	      displayed.
 
     2. Add the following line to the CONFIG.SYS.

          DEVICE=[drive:directory]RTR16NDS.OS2

        This line should be entered immediately following the line
        which installs the PROTMAN.OS2 device driver.

	NOTE: You must specify a DPATH in CONFIG.SYS to the subdirectory
	      containing the RTR16NDS.MSG file to enable driver error
	      messages and alleviate the "Cannot find message file" error
	      at boot time.

     3. Add the following section to PROTOCOL.INI

          [RTR16NDS_NIF]
              DriverName = RTRNDS$

     4. Add RTR16NDS_NIF to the bindings list of the protocol in the
        PROTOCOL.INI. An example protocol section follows.

          [NETBEUI_XIF]
               DriverName = NETBEUI$
               Bindings = RTR16NDS_NIF

RTR16NDS Parameters

     The PROTOCOL.INI file defines the configuration of protocol
     and NDIS drivers. The following table summarizes RTR16NDS
     parameters.

DRIVERNAME
     Identifies the network device driver. The DRIVERNAME is RTRNDS$
     for the first driver and RTRNDS2$ for the second, and so on.
     This parameter is required.

IOADDRESS
     If no IOADDRESS is specified, the driver will search for an
     adapter at all I/O addresses until one is found. Otherwise,
     only the specified I/O address is checked. This parameter is
     required when multi adapter support is desired.

MAXTRANSMITS
     Sets the number of transmits that can be queued simultaneously
     by the driver.

NUMRXBUFFERS
     Sets the number of receive buffers to allocate.

RXBUFFERSIZE
     Sets the size of buffers used to queue received frames in the
     driver. Several buffers may be required to queue a large
     frame. Performance is improved if a received frame fits in one
     buffer. Use the following formula to determine maximum frame
     size. MediaMaxSize equals 17960 @ 16 Mbps, or 4490 @ 4 Mbps.

     MaxFrameSize = 
          min(min(8, NumReceiveBuffers) x ReceiveBufferSize, MediaMaxSize)

PSEUDODMA
     This entry informs the driver to use pseudo DMA on 16 bit ISA
     adapters. Normally, 16 bit adapters use DMA bus master mode.
     Note that the pseudo DMA option is not supported on Micro-Channel
     adapters. Also note that the 8 bit ISA adapter does not support bus
     master DMA, and always defaults to the pseudo DMA mode. This entry
     is not followed by an equal sign.

NOEARLYRELEASE
     This entry informs the driver to disable early token release.
     Early token release reduces the average time another network
     adapter must wait to transmit a frame. This entry is not
     followed by an equal sign.

NETADDRESS
     This entry allow the driver to override the burned in address
     (BIA). The entry must be a 12 character string of hexadecimal
     digits, and must be enclosed in quotes.

RPL
     This entry provides compatibility when RPLing under OS/2 and
     certain versions of IBM LAN Server. This parameter should be
     specified for each station performing RPL, as required. This
     entry should NOT be specified on server or non-RPLing PC's.


For example, the following is a sample PROTOCOL.INI file:

     [RTR16NDS_NIF]
          DRIVERNAME = RTRNDS$
          IOADDRESS = 0xA20
          MAXTRANSMITS = 10
          NUMRXBUFFERS = 12
          RXBUFFERSIZE = 1024
          NETADDRESS = "400000000312"
