This file explains how to install the SCO Unix MDI Driver.
3) System Requirement
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
A) Hardware Requirements :
o An IBM-compatible personal computer with 80386 or higher
microprocessor and PCI bus.
o This adapter.
B) Firmware Requirements :
o Fully complient Rev. 2.0 or above PCI BIOS supplied with
the PC.
o If the adapter makes use of Digital Semiconductor 21050
(PCI-PCI bridge) or any other PCI-PCI bridge, the PCI
BIOS should support PCI-PCI bridge architecture.
C) Software Requirements :
o OpenServer or higher version, or
SCO Unix 3.2.4 or higher version
o SCO AHS
4) Installing Software
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
To install the SCO Unix MDI Device Driver:
A) Copy the file SUM333TD.Z to SUM333T.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 SUM333T.dd.Z
and compare the results.
B) Uncompress SUM333T.dd.Z to SUM333T.dd, using :
uncompress SUM333T.dd
C) Copy the file to a diskette. To create a 3.5" floppy in
drive 0, use :
dd if=SUM333T.dd of=/dev/rfd0135ds18
Mark the diskette:
Digital Semiconductor 2104x/2114x 10/100 mbps Ethernet
Controller MDI driver Rel.03.33
D) Run custom. From the menu select :
Software -> Install New -> From Host -> Media Floppy -> Full
E) Put the distribution diskette in the drive and select continue.
F) When prompted for distribution floppy 1, just press enter.
G) When custom has completed, remove the diskette and quit custom.
H) Run netconfig. Add the desired chain. The DC21X4 drivers are
called:
"Digital Semiconductor 2104x Ethernet Controller" and
"Digital Semiconductor 2114x 10/100 mbps Ethernet Controller"
NOTE: For boards with more than one Digital Semiconductor
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.
I) You can change the default value of the media by using the
"Advanced Options..." option in the menu.
J) When the chain has been configured, select "Exit" from the
netconfig menu. If you don't wish to modify the space.c
file relink the kernel at the prompt.
K) If you wish to change parameters in the space.c file, edit
/etc/conf/pack.d/d21x/space.c and make the required changes.
The changes will apply to all the installed boards.
L) To activate the adapter, you must reboot. When the system boots,
you should see the following message among the other
configuration messages:
%d21x 0x2000-0x2200 5 - type=DC21040/TP addr=12-34-56-78-9a-bc
or
%d21x 0x2000-0x2200 5 - type=DC21140/100TX addr=12-34-56-78-9a-bc
with the appropriate I/O addresses, IRQ, serial media and IEEE
address.
5) Parameters
ÄÄÄÄÄÄÄÄÄÄ
The space.c file contains the different parameters that can be
modified. They can be divided into several groups:
A) 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
B) Driver tuning parameters:
XXX_RX_BUFS_TO_POST
C) 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 netconfig, by running the reconfiguration
script.
The serial mode interface can be changed during netconfig as
explained before.
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.
