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 LLI Device Driver:

Copying the distribution files
------------------------------

- Copy the file SUL430TD.Z to SUL430T.dd.Z on a SCO Unix machine.
The number in parentheses near the file's name (above) is the checksum
for the file. To verify, use:
sum -r SUL430T.dd.Z
and compare the results.
- Uncompress SUL430T.dd.Z to SUL430T.dd, using:
uncompress SUL430T.dd
- Copy the file to a diskette. To create a 3.5" floppy in drive 0, use:
dd if=SUL430T.dd of=/dev/rfd0135ds18
Mark the diskette:
Intel 21x4x based 10/100 Mbps Ethernet Controller LLI Driver
Release 4.3.0

- Run custom. From the menu select:
Custom -> Install -> A New Product -> Entire Product

For SCO OpenServer, run the Software Manager. From the menus select:
Software -> Install New -> From Host -> Media Floppy -> Full

- Put the distribution diskette in the drive and select continue.

- When prompted for distribution floppy 1, just press enter.

- When custom has completed, remove the diskette and quit custom.

- Run netconfig. Add the desired chain. The D21X drivers are called:
d21x0, d21x1, d21x2 and d21x3. Remember that d21x0 must be configured
first, before any other driver is configured.

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. If only one port is used,
it must be the first port (as it is found on the bus
by the PCI BIOS).

- When the chain has been configured, select 'q' from the netconfig menu.
If you don't wish to modify the space.c file relink the kernel at the
prompt.

- If you wish to change parameters in the space.c file, edit
/etc/conf/pack.d/d21x0/space.c and make the required changes.
The changes will apply to all the installed boards.

NOTE: If your system does not support 32-bit protected mode PCI
BIOS calls, you MUST modify the parameter XXX_HW_ACCESSES
to the PCI mechanism appropriate to your system (see space.c
for details).

- To activate the adapter, you must reboot. When the system boots, you
should see the following message among the other configuration messages:

%d21x 0x2000-0x207F 5 - type=DC21040/TP addr=12-34-56-78-9a-bc

%d21x 0x2000-0x207F 5 - type=DC21140/100TX addr=12-34-56-78-9a-bc

with the appropriate I/O addresses, IRQ, serial media and IEEE address.

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_HW_ACCESSES
XXX_DC2114X_SERIAL_MODE
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 */
2. Driver tuning parameters:
XXX_RX_BUFS_TO_POST
XXX_RX_PKTS_QUEUED_THRESH_HI
XXX_RX_PKTS_QUEUED_THRESH_LO
XXX_MAX_USRS

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.

Space.c is NOT the place to modify the board's slot number line.
This must be modified in netconfig, by running the reconfiguration
script.

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.

2. Wrong HW access method for PCI configuration space:

If the XXX_HW_ACCESSES parameter in space.c is set to a value not
supported by your system there will be problems at boot time. Set
this parameter to a value that is supported by your system.

By default, the parameter is set so the driver uses 32-bit protected
mode PCI BIOS calls.

3. Driver binds to wrong PCI board (network):

When multiple PCI boards are installed, the chains are bound to
the adapters in the order that the adapters are found on the PCI
bus by the PCI BIOS. Thus, d21x0 will bind to the first adapter
found by the PCI BIOS, d21x1 to the second etc. Removing or adding
boards without changing the configuration in netconfig can cause
a shift in the order that chains are bound. Also, mis-identifying
the order in which the adapters are found by the BIOS can cause
wrong bindings. This is especially true when using boards with
PCI-PCI bridges. The adapters on such boards are located on a PCI
bus with a number higher than 0 (bus #1, #2 etc.) and will be found
by the PCI BIOS after all the devices on bus zero.

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.
