Installation
------------
Copy the driver for your processor to
devs:networks/x-surf.device. Don't forget to remove the
three digits in the name, the device will not work if the
filename has a "000" or a "040" at the end!
Make a directory in envarc: named "sana2". This can be done
with your favourite directory tool, or by typing in a shell:
makedir envarc:sana2
Copy the file x-surf.config to that directory, then restart
your computer, so this directory and file is copied
automatically to ENV:. If you want to avoid a restart, you
can also copy the directory to ENV: manually. Remember
that the old device can only be removed from memory if the
OpenCount is 0, and you enter "avail flush" in a shell. If
this is greek to you, a simple restart will serve your
needs.
changes from V1.1
-----------------
1. The new driver now supports more than one X-Surf. Up to
eight boards are supported. Use the same device, and the
next unit number to access the next board. The order of the
unit numbers is taken from the order in the config chain,
i.e. the X-Surf in the first slot is Unit 0.
2. The full duplex mode is now supported (20MBit). In order to
activate it, the config file "env:sana2/x-surf.config" must
contain the keyword "FullDuplex" followed by "1" for the
unit you want to activate full duplex for. Example:
--- cut ---
# **** x-surf config file *****
#
Unit0.FullDuplex 0
Unit1.FullDuplex 1
--- cut ---
Board number 0 will work with 10Mbit, while board number 1
uses 20MBit. Comments in the file are marked with a # sign.
If no configuration file is found, half-duplex mode will be
activated.
Changes are only stored in the board's EEPROM (non-volatile
memory) if the config-file and the contents of the EEPROM
are different.
3. Timer.device is now being used for all timing-critical
routines. These are:
- ISA-PNP
- r/w to/from EEPROM
This avoids the hickups of the mouse pointer during first
open of the device.
4. The device now uses soft-interrupts instead of a task to
serve the hardware-IRQs.
5. The size of the driver has been reduced by some optimizing
of the code. This has also improved the speed, the
performance of this driver is now even better.
6. The Promisc-mode of the driver has been corrected (reception
of all packets of the network).
Tests
-----
The driver is working properly on all test-computers since a
couple of days. Some hubs do not display the full-duplex
mode, but it can be used (proof: performance stays stable
when adding another data stream in the opposite direction).
Especially Kingston-Hubs do not seem to display the full
duplex mode (LED stays off).
We still don't know where the problem with Mac-emulators is
located. Please report any changes with this new driver,
because we believe that the corrected promisc-mode could be
a solution. None of the beta-testers has a Mac-emulator, so
we need your help in order to test this.
Versions
--------
There are versions for 68000, 68020 and 68040 processors.
Many customers have asked for specialized versions for 68030
and 68060 processors, and I want to answer these questions
here:
The different versions are only different regarding the
addressing modes of the specific processor. Since 68020 and
68030 are identical in the used addressing modes, it would
not make any sense to re-compile for 68030. The same
applies to 68060 processors: A re-compilation would result
in an identical binary file with a different file name. I
hope this answers all questions in this regard, and the
e-mail support can answer more important questions.
If you have any comments, bugreports or something similar,
for example just want to tell us that the driver works as
you expected, feel free to write:
