This page and the driver you can find here are no longer maintained by me.
From version 2.4 on, mainstream Linux kernels contain the driver for the
PCA-200E board.
However you still need the user space tools to do real networking with
ATM.
Thanks to Christophe Lizzi (lizzi at cnam.fr) for continuing this work.

The PCA-200E ATM
adapter series built by FORE Systems
offer 155 Mbps ATM networking access for PCI-Bus based systems. The adapters
are quite popular, therefore at Dresden University of Technology we
currently attempt to support it under the highly popular free Linux
operating system.
This driver is intended for use with the PCA-200E, the PCI bus version of
FORE Systems'
ForeRunner
200E ATM adapters series.
It does not work with the PCA-200 (note the missing E), since
this is a completely different chipset. It also does not work with
the "LE" variants.
The driver is known to work on Intel Linux boxes. A few efforts have been
spent to make it work on Alpha, but with limited success.
The PCA-200E Linux driver is designed to fit into the framework provided by
ATM-on-Linux.
You must have ATM-on-Linux support in your Linux kernel if you want
to play with the PCA-200E driver.
Since this is a Linux driver, you should have suitable Linux kernel sources, too.
The current version is 0.4 for 2.1.x Linux kernels and 0.3 for 2.0.x Linux
kernels. Version 0.3 is configured to be built as a kernel loadable module,
whereas version 0.4 is recommended to be compiled directly into the kernel.
If justified later, the driver could well be part of the
ATM-on-Linux distribution
by Werner Almesberger.
The driver has been placed under the GNU General Public License.
To use the driver, you need the firmware binary which is intellectual
property of FORE Systems.
This driver is beta software. No warranty of any kind is made if you will
use the driver. Be warned that there could be bugs and problems.
- CBR transmit support (4 shapers)
- FORE spec: 4 CBR connections without best-effort traffic or
max. 3 CBR connections with signalling
- tested: 2 concurrent CBR connections not influencing each other
- AAL0 transmit support
- sending 52(!) byte cells (see the Linux-ATM-API) works
- reception of raw cells currently doesn't trigger interrupts ->
delivery delayed until AAL5 data is received - Any ideas why?
- VPI limited to 0 - VCI must be in the range 1 to 1023
- Seems to work fine with SMP
Since the PCA-200E driver actually is only a side product of the work on
the DROPS project, support will be
limited somehow.

- Get the PCA-200E driver package from the download section in this document.
- Follow the instructions in the INSTALL file.
