1.1 PRODUCT OVERVIEW
The CS8900-based ISA Ethernet Adapters from Cirrus Logic follow
IEEE 802.3 standards and support half or full-duplex operation in ISA bus
computers on 10 Mbps Ethernet networks. The adapters are designed for operation
in 16-bit ISA or EISA bus expansion slots and are available in
10BaseT-only or 3-media configurations (10BaseT, 10Base2, and AUI for 10Base-5
or fiber networks).
CS8920-based adapters are similar to the CS8900-based adapter with additional
features for Plug and Play (PnP) support and Wakeup Frame recognition. As
such, the configuration procedures differ somewhat between the two types of
adapters. Refer to the "Adapter Configuration" section for details on

3.0 LOADING THE DRIVER AS A MODULE
===============================================================================
3. Loading the Driver as a Module
=================================
If the driver is compiled as a loadable module, you can load the driver module
with the 'modprobe' command. Many of the adapter's configuration parameters can
be specified as command-line arguments to the load command. This facility
provides a means to override the EEPROM's settings or for interface
with the 'modprobe' command. Many of the adapter's configuration parameters can
be specified as command-line arguments to the load command. This facility
provides a means to override the EEPROM's settings or for interface
configuration when an EEPROM is not used.
Example:
Example::
insmod cs89x0.o io=0x200 irq=0xA media=aui
This example loads the module and configures the adapter to use an IO port base
address of 200h, interrupt 10, and use the AUI media connection. The following
configuration options are available on the command line:
* io=### - specify IO address (200h-360h)
* irq=## - specify interrupt level
* use_dma=1 - Enable DMA
* dma=# - specify dma channel (Driver is compiled to support
Rx DMA only)
* dmasize=# (16 or 64) - DMA size 16K or 64K. Default value is set to 16.
* media=rj45 - specify media type
configuration options are available on the command line::
io=### - specify IO address (200h-360h)
irq=## - specify interrupt level
use_dma=1 - Enable DMA
dma=# - specify dma channel (Driver is compiled to support
Rx DMA only)
dmasize=# (16 or 64) - DMA size 16K or 64K. Default value is set to 16.
media=rj45 - specify media type
or media=bnc
or media=aui
or media=auto
* duplex=full - specify forced half/full/autonegotiate duplex
duplex=full - specify forced half/full/autonegotiate duplex
or duplex=half
or duplex=auto
* debug=# - debug level (only available if the driver was compiled
for debugging)
debug=# - debug level (only available if the driver was compiled
for debugging)
NOTES:
**Notes:**
a) If an EEPROM is present, any specified command-line parameter
will override the corresponding configuration value stored in
EEPROM.
b) The "io" parameter must be specified on the command-line.
b) The "io" parameter must be specified on the command-line.
c) The driver's hardware probe routine is designed to avoid
writing to I/O space until it knows that there is a cs89x0
card at the written addresses. This could cause problems
with device probing. To avoid this behaviour, add one
to the `io=' module parameter. This doesn't actually change
to the ``io=`` module parameter. This doesn't actually change
the I/O address, but it is a flag to tell the driver
to partially initialise the hardware before trying to
identify the card. This could be dangerous if you are
not sure that there is a cs89x0 card at the provided address.
For example, to scan for an adapter located at IO base 0x300,
specify an IO address of 0x301.

4.0 COMPILING THE DRIVER
===============================================================================
4. Compiling the Driver
=======================
The cs89x0 driver can be compiled directly into the kernel or compiled into
a loadable device driver module.
Just use the standard way to configure the driver and compile the Kernel.
4.1 COMPILING THE DRIVER AS A LOADABLE MODULE
To compile the driver into a loadable module, use the following command
(single command line, without quotes):
"gcc -D__KERNEL__ -I/usr/src/linux/include -I/usr/src/linux/net/inet -Wall
-Wstrict-prototypes -O2 -fomit-frame-pointer -DMODULE -DCONFIG_MODVERSIONS
-c cs89x0.c"
4.2 COMPILING THE DRIVER TO SUPPORT MEMORY MODE
Support for memory mode was not carried over into the 2.3 series kernels.
4.3 COMPILING THE DRIVER TO SUPPORT Rx DMA
4.1. Compiling the Driver to Support Rx DMA
-------------------------------------------
The compile-time optionality for DMA was removed in the 2.3 kernel
series. DMA support is now unconditionally part of the driver. It is
enabled by the 'use_dma=1' module option.

If an IO conflict occurs, run the CS8900/20 Setup Utility and perform a
diagnostic self-test. Normally, the ISA resource in conflict will fail the
self-test. If so, reconfigure the adapter selecting another choice for the
resource in conflict. Run the diagnostics again to check for further IO
conflicts.
In some cases, such as when the PC will not boot, it may be necessary to remove
the adapter and reconfigure it by installing it in another PC to run the
CS8900/20 Setup Utility. Once reinstalled in the target system, run the
diagnostics self-test to ensure the new configuration is free of conflicts
