Driver Installation From The Command Line Prompt

If you currently have an older SCO Unix driver installed in your system, you should remove it prior to installing a newer version. Use the netconfig and custom utilities to remove the older driver version. Refer to your SCO Unix OS documentation as needed. After removing your existing driver, you may then proceed with installing a newer SCO Unix driver.

Note:The custom and netconfig utilities are provided by SCO.

Follow the steps listed below:

1 Login in as "root."

2 Insert the AMD SCO Unix LLI driver diskette into floppy drive "A." Make sure the floppy drive in which this diskette is inserted is "fd0." This is the default floppy drive where the SCO Unix custom utility will look for the driver and the corresponding installation script.

3 Run the custom utility by typing:

  custom
  

Then press <Enter>

Note:If you are using drive "B", run the custom utility with the "-m" option to specify the correct drive where the AMD SCO Unix LLI driver diskette is located.

4 In the custom utility main menu, you will see four main options at the upper left hand corner of the screen (Install, Remove, List, Quit). Use the right/left arrow keys to select the "Install" option and then press <Enter>.

5 Next, use the up/down arrow keys to select "A new product" and press <Enter>.

6 Three options will be displayed (Entire Product, Packages, Files). Select "Entire Product" and press <Enter>.

7 The following message will be displayed:

  Insert the requested volume and press <Return> to continue
  the installation
  
  Insert: Distribution Floppy Volume 1

  Continue Quit

Press <Enter> to continue.

8 The following message will be displayed:

  Installing custom data files... 

  Insert the requested volume and press <Return> to continue
  the installation

  Insert: AMD PCNet Family LLI Driver Floppy Volume 1

  Continue Quit

Press <Enter> to continue.

9 The following message will be displayed:

  Extracting files...

  Checking file permissions... 

You will then be returned to the custom utility main screen.

10 Select "Quit" from the custom utility main options. Answer "Yes" you want to exit from the custom utility. You will then be returned to the Unix prompt.

11 Next, run the netconfig utility by typing:

  netconfig

Then press <Enter>.

The netconfig utility is used to configure the SCO Unix driver for different INT, DMA, and I/O address values. This utility is also used to add the driver to the protocol chain.

Note:The netconfig utility modifies the space.c file automatically and must be used in order to get proper support for PCI BIOS API calls.

12 The following will be displayed:

Available options: 1. Add a chain 2. Remove a chain 3. Reconfigure an element in a chain q. Quit Select Option:

Select option 1 (Add a chain) by typing:

  
  1

Then press <Enter>.

13 The following will be displayed:

  Select top level of chain to Add or q to quit:

Select the appropriate top level of chain for your system by entering the appropriate number (Num) value and pressing <Enter>.

14 Next, select the appropriate number (Num) value for the AMD PCnet Ethernet driver and press <Enter>.

15 Answer all of the questions asked by netconfig as appropriate for your system. Refer to your SCO Unix OS documentation as needed. Also, see the Software Keyword section in this manual for more details on keyword settings.

Note:If you need to modify keyword values, you should edit the space.c file as needed. The path for this file is:

  /etc/conf/pack.d/pnt0/space.c 
  

16 Select "quit" from the netconfig utility by typing "q" and then press <Enter>.

17 At this point, you should relink your kernel and reboot the system. Refer to your SCO Unix OS documentation as needed.

The installation of the SCO Unix LLI driver is now complete.

SCO Unix LLI Driver Keywords

Keywords can be added, deleted, and/or modified by manually editing the appropriate "#define" values in the "space.c" file. See Appendix B (Software Keywords) and your SCO Unix Manuals for more details. A sample version of this file is listed below:
