DOS ODI Driver Software: Broadcom NetXtreme™ 57XX User Guide

Installing the Driver Software

Configuring Parameters for the B57.com Driver (in the Net.cfg File)


The Open Data-Link Interface (ODI) application allows LAN drivers to work together irrespective of differences between the hardware and/or the protocol stacks of communicating computers. An intervening layer, called the link support layer (LSL), is responsible for routing different packet types between LAN drivers and protocol stacks.

Installing the Driver Software

Installing the DOS/ODI driver software involves the following steps:

  1. Verifying that the DOS 6.22 operating system files are installed on your computer hard disk or are available on a removable storage device.
  2. Installing the DOS/ODI driver software in the DOS environment.
  3. If necessary, reconfiguring the driver software after installation.

Pre-Installation Requirements

  1. Verify that the Broadcom Ethernet controller driver software has been installed on your computer and install it if it has not (see Installing the Driver Software in Windows Driver Software). Otherwise, you cannot use a Broadcom Ethernet controller in the DOS environment.
Note: To successfully install the controller driver for DOS, the controller must be installed in the computer before you install the driver.
  1. Install the DOS 6.22 files on your computer hard disk or have them available on a removable storage device.

Installing the DOS ODI Driver on DOS 6.22

  1. Copy the DOS ODI driver file to the root directory of the hard disk.
  2. Copy Lsl.com, Ipxodi.com, and Vlm.com to the same directory (these files are provided by Novell).
  3. Edit the Autoexec.bat file by adding the following lines:

    C:\LSL
    C:\B57
    C:\IPXODI
    C:\VLM

  1. Edit the Net.cfg file and place the file in the same location as the Autoexec.bat file (located in drive C) to configure the driver to bind with different frame types. 

    Example:

    LINK DRIVER B57
    FRAME ETHERNET_802.2
    FRAME ETHERNET_802.3
    FRAME ETHERNET_II
    FRAME ETHERNET_SNAP

    NetWare DOS Requester
    FIRST NETWORK DRIVE=F
    NETWARE PROTOCOL=NDS BIND

    PROTOCOL IPXODI

  2. Restart the computer to complete the installation.
  3. As the files are being loaded, the computer attempts to attach to a Netware server using the frame types specified in Net.cfg.  If the connection is successful, a dialog box appears. 
  1. Change to drive F and log on to the Netware server.

    F: <enter>

    F:\login admin <enter>

Note: The driver loads during system configuration, and the Broadcom banner, the controller name, the MAC address, the IRQ number, the detected line speed, and the BUSNUM and DEVNUM of the controller are displayed. If the driver fails to load, an initialization fail message appears.

Configuring Parameters for the B57.com Driver (in the Net.cfg file)

The following are optional custom keywords used in the Net.cfg file:

The first two keywords (BUSNUM and DEVNUM) are used concurrently and have been included for manufacturing purposes.  Do not use them unless you are familiar with PCI device configuration. These two keywords are needed if multiple Broadcom 57XX Ethernet controllers are installed on a computer and each controller must be loaded in a specific order.

BUSNUM specifies the PCI bus number and DEVNUM specifies the device number that is assigned to the board when it is configured by the PCI BIOS.

The values for these adapter parameters are displayed in hexadecimal notation when the driver loads (the Net.cfg file expects hexadecimal values). A PCI device scan utility can also be used to find this information. If the driver loads on a single controller, the displayed values can be used in the Net.cfg file.

If a PCI scan utility displays card 1 at bus 4 and device 11 (hexadecimal), and card 3 at bus 3 and device 13 (hexadecimal), the following load instructions are written to the Net.cfg file (load card 3 first, and optionally load card 1 second):

  LINK DRIVER B57
  BUSNUM 3
  DEVNUM 13 (13 hex = 19 decimal)
  LINK DRIVER B57
  BUSNUM 4
  DEVNUM 11 (11 hex = 17 decimal)

The FUNNUM keyword is used to determine which function/port the driver is to load on when using a multifunction (multiport) controller. Function number values are limited to 0 and 1, for the first and second function of the controller.

The SUBVID keyword is used to for load the driver only on the first network interface card found that has a subvendor ID (SVID) that matches the one set in Net.cfg. The driver ignores all other network interface cards that do not have a matching SVID. SIBVID expects a hexadecimal number.

Example:

LINK DRIVER B57
SUBVID 14E4

SUBVID cannot be used with BUSNUM, DEVNUM or FUNNUM.

The MODEL keyword is for loading the driver only on the first network interface card found that has a subvendor ID (SVID) that matches the one set in MODEL. The driver ignores all other NICs that do not have a matching SVID.  MODEL expects a decimal number.

Example:

LINK DRIVER B44
MODEL 5348
