# #
##############################################################################
1. Overview:
This Readme file explains how to install the SCO OpenServer MDI driver.
This driver supports the following adapters:
Compu-Shack FASTline-PCI UTP Quattro (10/100 BaseTx)
Compu-Shack FASTline-PCI UTP (10/100 BaseTx)
Compu-Shack FASTline-PCI FO (100 BaseFx).
A limitation of this driver is that it can only support up to four
controller ports.
2. Preinstallation Hardware and Software Requirements:
A. Hardware Requirements:
o An IBM-compatible personal computer with 80386 or higher
microprocessor and PCI bus.
o A DECchip 21140-based Ethernet adapter for that bus or
o A DECchip 21142/3-based Ethernet adapter for that bus.
B. Firmware Requirements:
o Fully compliant Rev. 2.0 or above PCI BIOS supplied with the PC.
o If Ethernet adapter makes use of DECchip 21050/21152 (PCI-PCI bridge),
PCI BIOS should support PCI-PCI bridge architecture.
C. Software Revision Requirements:
o SCO OpenServer Release 5.0.0 or higher version
3. Files and Directories:
This directories contains the following files:
Table 1: The SCO Unix MDI driver Directory Files
---------------------------------------------------------------------------
README.TXT This File
---------------------------------------------------
CUSTOM.DST or
FASTLINE.TAR (contains VOL.000.000)
The compressed image of the distribution diskette.
The FASTline distribution diskette contains all the
files required for installing the driver using
custom and netconfig, in particular:
- custom related scripts.
- netconfig related scripts and AOF files.
- Driver.o, the driver
- Space.c, the parameter file
- space.h - header file, not intended to be
modified
---------------------------------------------------------------------
4. Installing the Hardware Boards:
To install the Compu-Shack FASTline adapters see the User's Guide.
5. Installing Software:
To install the SCO Unix MDI Device Driver:
Copying the distribution files
------------------------------
- If you install the driver from the distribution diskette, the file
CUSTOM.DST in the subdirectory \SCO can directly be read by the SCO
software manager.
- If you got an update file containing a tar archive FASTLINE.TAR copy this
file to a SCO Unix machine. To extract the archive type
tar -xf FASTLINE.TAR
and a file VOL.000.000 will be created. You can either copy this file to
MS-DOS formatted diskette as \SCO\CUSTOM.DST or use it directly as an
installation image file.
- Run custom. From the menu 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 FASTLINE drivers are called:
"Compu-Shack FASTline Quattro UTP"
"Compu-Shack FASTline UTP"
"Compu-Shack FASTline FO"
NOTE: For QUATTRO boards with four one Ethernet Controllers on
them, a driver must be installed for each active port on the
board. This is similar to installing two boards, each with
one port.
Not all ports must be active.
- You can change the default value of the media by using the
"Advanced Options..." option in the menu.
- 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.
- If you wish to change parameters in the space.c file, edit
/etc/conf/pack.d/cfl/space.c and make the required changes.
The changes will apply to all the installed boards.
- To activate the adapter, you must reboot. When the system boots, you
should see the following message among the other configuration messages:
%cfl 0x2000-0x2200 5 - type=DC21140/100TX addr=00-00-cb-01-23-45
with the appropriate I/O addresses, IRQ, serial media and IEEE address.
6. 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_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 netconfig, by running the reconfiguration
script.
The serial mode interface can be changed during netconfig as explained
before.
7. 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.
8. Driver's error messages (when working in debug level > 0)
In "cfli" the 'i' stands for a number between 0 and 3, indicating
the particular instance of the driver the message is reported by.
