5. Installing the Hardware Boards:
Installing the Intel 21040/21140/21140A/21041/21142/21143 PCI Evaluation
Board
To install the EB40 or EB140 or EB41 or EB140A-TX or EB142 see the Intel
21040 PCI Evaluation Board User's Guide or the Intel 21140 PCI Evaluation
Board User's Guide or the Intel 21041 PCI Evaluation Board User's Guide or
the Intel 21140A PCI Evaluation Board User's Guide or the Intel 21142 PCI
Evaluation Board User's Guide or the Intel 21143 PCI Evaluation Board User's
Guide.
6. Installing Software:
To install the SCO Unix GEMINI Device Driver:
Copying the distribution files
------------------------------
- Create/Choose a temporary directory (e.g. /tmp/install), use:
mkdir /tmp/install
- Change the current directory to the above directory, use:
cd /tmp/install
- Copy the file SUG430TD.PKG to this directory.
For DOS file, use:
doscp SUG430TD.PKG .
The number in parentheses near the file's name (above) is the checksum
for the file. To verify, use:
sum -r SUG430TD.PKG
and compare the results.
- Remove any previously installed versions using:
netcfg
pkgrm d21x
TO USE THE PACKAGE FILE DIRECTLY:
- Install the package using:
pkgadd -d /tmp/install/SUG430TD.PKG
CONTINUE THE INSTALLATION PROCESS:
- Run netconfig. Add the desired chain. The d21x drivers are called:
"Intel 2104x based 10 Mbps Ethernet Controller" and
"Intel 2114x based 10/100 Mbps Ethernet Controller"
During this process a dialog will allow you to modify the advanced
option. This option allows the user to override the medium type chosen
by the board designer. We advise users not to change the default
settings unless really necessary. The same dialog can be reached after the
installation is compeleted through the "Modify Hardware Configuration"
item in netcfg's "Hardware" menu.
NOTE: For boards with more than one Intel 21X4X on
them, a driver must be installed for each active port on the
board. Thus, if a board has two separate ports, two separate
chains must be created in order to connect both ports to
networks. This is similar to installing two boards, each with
one port.
Not all ports must be active.
- When the chain has been configured, select "Exit" from the netconfig menu.
- If you wish to change parameters in the space.c file, edit
/etc/conf/pack.d/d21x/space.c and make the required changes.
When finished, Relink the kernel manually using:
/etc/nd stop
/sbin/modadmin -U d21x
/etc/conf/bin/idbuild -M d21x
/etc/nd start
- In some versions of UnixWare 7 you must reboot the machine in order for
some of the changes to take effect. In others it is enough to do the
following:
/etc/nd stop
/sbin/modadmin -U d21x
/etc/nd start
7. Parameters
The space.c file contains the different parameters that can be modified.
They can be divided into several groups:
1. Port parameters. These include:
XXX_BUS_ARBITRATION
XXX_BURST_LENGTH
XXX_CACHE_ALIGNMENT
XXX_PASS_BAD_FRAMES
XXX_BACKOFF_CNTR
XXX_10MB_THRESHOLD
XXX_100MB_THRESHOLD
XXX_PARITY_ERROR_RESPONSE
XXX_LATENCY_TIMER
XXX_CRC_CALC
XXX_DC2114X_GPR_CTRL
XXX_DC2114X_GPR_DATA
XXX_TURBO
XXX_SNOOZE
XXX_MWI, /* Enable/Disable MWI extended PCI command */
XXX_MRM, /* Enable/Disable MRM extended PCI command */
XXX_MRL /* Enable/Disable MRL extended PCI command */
XXX_0_MAC_ADDR
XXX_1_MAC_ADDR
XXX_2_MAC_ADDR
XXX_3_MAC_ADDR
2. Driver tuning parameters:
XXX_RX_BUFS_TO_POST
3. Driver diagnostics control:
XXX_DEBUG
The meaning of each is explained in detail in the space.c file, including
allowed values for each parameter. The values in space.c apply to ALL
the installed boards, except the MAC address parameter.
Space.c is NOT the place to modify the board's slot number line.
This must be modified in netcfg, by running the reconfiguration "resmgr"
script.
The serial mode interface can be changed during netcfg as explained
before.
8. Errors and trouble shooting
1. Mismatch between PCI configuration and netconfig/space.c:
In order for the adapter to work correctly, the same values that are
used during the PCI configuration (e.g CFLT) must be used in the
space.c file. Mismatches may cause the adapter to malfunction, or even
hang the system.
Currently, the PCI setup takes precedence except for the value for the
latency timer, which is taken from the space.c file.
9. Driver's error messages (when working in debug level > 0)
In "d21xi" the 'i' stands for a number between 0 and 3, indicating
the particular instance of the driver the message is reported by.

For DC21140/DC21140A/DC21142 based adapters, the selected serial mode is
AUTOSENSE and there are GPR values in space.c that override the defaults.

Upgrading Drivers
See the components page available on the Intel World Wide Web
Internet site at:
http://developer.intel.com/design/network/new21/download/dsc-software-nc.htm
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.
