+===============================================================================
+
+
+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
+configuring both types of adapters.
+
+
+1.2 DRIVER DESCRIPTION

+
+
+2.0 ADAPTER INSTALLATION and CONFIGURATION
+===============================================================================
+
+Both the CS8900 and CS8920-based adapters can be configured using parameters
+stored in an on-board EEPROM. You must use the DOS-based CS8900/20 Setup
+Utility if you want to change the adapter's configuration in EEPROM.
+
+When loading the driver as a module, you can specify many of the adapter's
+configuration parameters on the command-line to override the EEPROM's settings
+or for interface configuration when an EEPROM is not used. (CS8920-based
+adapters must use an EEPROM.) See Section 3.0 LOADING THE DRIVER AS A MODULE.
+
+Since the CS8900/20 Setup Utility is a DOS-based application, you must install
+and configure the adapter in a DOS-based system using the CS8900/20 Setup
+Utility before installation in the target LINUX system. (Not required if
+installing a CS8900-based adapter and the default configuration is acceptable.)
+
+
+2.1 CS8900-BASED ADAPTER CONFIGURATION
+
+CS8900-based adapters shipped from Cirrus Logic have been configured
+with the following "default" settings:
+
+ Operation Mode: Memory Mode
+ IRQ: 10
+ Base I/O Address: 300
+ Memory Base Address: D0000
+ Optimization: DOS Client
+ Transmission Mode: Half-duplex
+ BootProm: None
+ Media Type: Autodetect (3-media cards) or
+ 10BASE-T (10BASE-T only adapter)
+
+You should only change the default configuration settings if conflicts with
+another adapter exists. To change the adapter's configuration, run the
+CS8900/20 Setup Utility.
+
+
+2.2 CS8920-BASED ADAPTER CONFIGURATION
+
+CS8920-based adapters are shipped from Cirrus Logic configured as Plug
+and Play (PnP) enabled. However, since the cs89x0 driver does NOT
+support PnP, you must install the CS8920 adapter in a DOS-based PC and
+run the CS8900/20 Setup Utility to disable PnP and configure the
+adapter before installation in the target Linux system. Failure to do
+this will leave the adapter inactive and the driver will be unable to
+communicate with the adapter.
+
+
+ ****************************************************************
+ * CS8920-BASED ADAPTERS: *
+ * *
+ * CS8920-BASED ADAPTERS ARE PLUG and PLAY ENABLED BY DEFAULT. *
+ * THE CS89X0 DRIVER DOES NOT SUPPORT PnP. THEREFORE, YOU MUST *
+ * RUN THE CS8900/20 SETUP UTILITY TO DISABLE PnP SUPPORT AND *
+ * TO ACTIVATE THE ADAPTER. *
+ ****************************************************************
+
+
+
+
+3.0 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
+configuration when an EEPROM is not used.
+
+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
+ or media=bnc
+ or media=aui
+ or medai=auto
+* 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)
+
+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.
+
+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
+ the I/O address, but it is a flag to tell the driver
+ topartially 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.
+
+d) The "duplex=auto" parameter is only supported for the CS8920.
+
+e) The minimum command-line configuration required if an EEPROM is
+ not present is:
+
+ io
+ irq
+ media type (no autodetect)
+
+f) The following additional parameters are CS89XX defaults (values
+ used with no EEPROM or command-line argument).
+
+ * DMA Burst = enabled
+ * IOCHRDY Enabled = enabled
+ * UseSA = enabled
+ * CS8900 defaults to half-duplex if not specified on command-line
+ * CS8920 defaults to autoneg if not specified on command-line
+ * Use reset defaults for other config parameters
+ * dma_mode = 0
+
+g) You can use ifconfig to set the adapter's Ethernet address.
+
+h) Many Linux distributions use the 'modprobe' command to load
+ modules. This program uses the '/etc/conf.modules' file to
+ determine configuration information which is passed to a driver
+ module when it is loaded. All the configuration options which are
+ described above may be placed within /etc/conf.modules.
+
+ For example:
+
+ > cat /etc/conf.modules
+ ...
+ alias eth0 cs89x0
+ options cs89x0 io=0x0200 dma=5 use_dma=1
+ ...
+
+ In this example we are telling the module system that the
+ ethernet driver for this machine should use the cs89x0 driver. We
+ are asking 'modprobe' to pass the 'io', 'dma' and 'use_dma'
+ arguments to the driver when it is loaded.
+
+i) Cirrus recommend that the cs89x0 use the ISA DMA channels 5, 6 or
+ 7. You will probably find that other DMA channels will not work.
+
+j) The cs89x0 supports DMA for receiving only. DMA mode is
+ significantly more efficient. Flooding a 400 MHz Celeron machine
+ with large ping packets consumes 82% of its CPU capacity in non-DMA
+ mode. With DMA this is reduced to 45%.
+
+k) If your Linux kernel was compiled with inbuilt plug-and-play
+ support you will be able to find information about the cs89x0 card
+ with the command
+
+ cat /proc/isapnp
+
+l) If during DMA operation you find erratic behavior or network data
+ corruption you should use your PC's BIOS to slow the EISA bus clock.
+
+m) If the cs89x0 driver is compiled directly into the kernel
+ (non-modular) then its I/O address is automatically determined by
+ ISA bus probing. The IRQ number, media options, etc are determined
+ from the card's EEPROM.
+
+n) If the cs89x0 driver is compiled directly into the kernel, DMA
+ mode may be selected by providing the kernel with a boot option
+ 'cs89x0_dma=N' where 'N' is the desired DMA channel number (5, 6 or 7).
+
+ Kernel boot options may be provided on the LILO command line:
+
+ LILO boot: linux cs89x0_dma=5
+
+ or they may be placed in /etc/lilo.conf:
+
+ image=/boot/bzImage-2.3.48
+ append="cs89x0_dma=5"
+ label=linux
+ root=/dev/hda5
+ read-only
+
+ The DMA Rx buffer size is hardwired to 16 kbytes in this mode.
+ (64k mode is not available).
+
+
+4.0 COMPILING THE DRIVER
+===============================================================================
+
+The cs89x0 driver can be compiled directly into the kernel or compiled into
+a loadable device driver module.
+
+
+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
+
+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.
+
+4.4 COMPILING THE DRIVER INTO THE KERNEL
+
+If your Linux distribution already has support for the cs89x0 driver
+then simply copy the source file to the /usr/src/linux/drivers/net
+directory to replace the original ones and run the make utility to
+rebuild the kernel. See Step 3 for rebuilding the kernel.
+
+If your Linux does not include the cs89x0 driver, you need to edit three
+configuration files, copy the source file to the /usr/src/linux/drivers/net
+directory, and then run the make utility to rebuild the kernel.
+
+1. Edit the following configuration files by adding the statements as
+indicated. (When possible, try to locate the added text to the section of the
+file containing similar statements).
+
+
+a.) In /usr/src/linux/drivers/net/Config.in, add:
+
+tristate 'CS89x0 support' CONFIG_CS89x0
+
+Example:
+
+ if [ "$CONFIG_EXPERIMENTAL" = "y" ]; then
+ tristate 'ICL EtherTeam 16i/32 support' CONFIG_ETH16I
+ fi
+
+ tristate 'CS89x0 support' CONFIG_CS89x0
+
+ tristate 'NE2000/NE1000 support' CONFIG_NE2000
+ if [ "$CONFIG_EXPERIMENTAL" = "y" ]; then
+ tristate 'NI5210 support' CONFIG_NI52
+
+
+b.) In /usr/src/linux/drivers/net/Makefile, add the following lines:
+
+ifeq ($(CONFIG_CS89x0),y)
+L_OBJS += cs89x0.o
+else
+ ifeq ($(CONFIG_CS89x0),m)
+ M_OBJS += cs89x0.o
+ endif
+endif
+
+
+c.) In /linux/drivers/net/Space.c file, add the line:
+
+extern int cs89x0_probe(struct device *dev);
+
+
+Example:
+
+ extern int ultra_probe(struct device *dev);
+ extern int wd_probe(struct device *dev);
+ extern int el2_probe(struct device *dev);
+
+ extern int cs89x0_probe(struct device *dev);
+
+ extern int ne_probe(struct device *dev);
+ extern int hp_probe(struct device *dev);
+ extern int hp_plus_probe(struct device *dev);
+
+
+Also add:
+
+ #ifdef CONFIG_CS89x0
+ { cs89x0_probe,0 },
+ #endif
+
+
+2.) Copy the driver source files (cs89x0.c and cs89x0.h)
+into the /usr/src/linux/drivers/net directory.
+
+
+3.) Go to /usr/src/linux directory and run 'make config' followed by 'make'
+(or make bzImage) to rebuild the kernel.
+
+4.) Use the DOS 'setup' utility to disable plug and play on the NIC.
+
+
+5.0 TESTING AND TROUBLESHOOTING
+===============================================================================
+
+5.1 KNOWN DEFECTS and LIMITATIONS
+
+Refer to the RELEASE.TXT file distributed as part of this archive for a list of
+known defects, driver limitations, and work arounds.
+
+
+5.2 TESTING THE ADAPTER
+
+Once the adapter has been installed and configured, the diagnostic option of
+the CS8900/20 Setup Utility can be used to test the functionality of the
+adapter and its network connection. Use the diagnostics 'Self Test' option to
+test the functionality of the adapter with the hardware configuration you have
+assigned. You can use the diagnostics 'Network Test' to test the ability of the
+adapter to communicate across the Ethernet with another PC equipped with a
+CS8900/20-based adapter card (it must also be running the CS8900/20 Setup
+Utility).
+
+ NOTE: The Setup Utility's diagnostics are designed to run in a
+ DOS-only operating system environment. DO NOT run the diagnostics
+ from a DOS or command prompt session under Windows 95, Windows NT,
+ OS/2, or other operating system.
+
+To run the diagnostics tests on the CS8900/20 adapter:
+
+ 1.) Boot DOS on the PC and start the CS8900/20 Setup Utility.
+
+ 2.) The adapter's current configuration is displayed. Hit the ENTER key to
+ get to the main menu.
+
+ 4.) Select 'Diagnostics' (ALT-G) from the main menu.
+ * Select 'Self-Test' to test the adapter's basic functionality.
+ * Select 'Network Test' to test the network connection and cabling.
+
+
+5.2.1 DIAGNOSTIC SELF-TEST
+
+The diagnostic self-test checks the adapter's basic functionality as well as
+its ability to communicate across the ISA bus based on the system resources
+assigned during hardware configuration. The following tests are performed:
+
+ * IO Register Read/Write Test
+ The IO Register Read/Write test insures that the CS8900/20 can be
+ accessed in IO mode, and that the IO base address is correct.
+
+ * Shared Memory Test
+ The Shared Memory test insures the CS8900/20 can be accessed in memory
+ mode and that the range of memory addresses assigned does not conflict
+ with other devices in the system.
+
+ * Interrupt Test
+ The Interrupt test insures there are no conflicts with the assigned IRQ
+ signal.
+
+ * EEPROM Test
+ The EEPROM test insures the EEPROM can be read.
+
+ * Chip RAM Test
+ The Chip RAM test insures the 4K of memory internal to the CS8900/20 is
+ working properly.
+
+ * Internal Loop-back Test
+ The Internal Loop Back test insures the adapter's transmitter and
+ receiver are operating properly. If this test fails, make sure the
+ adapter's cable is connected to the network (check for LED activity for
+ example).
+
+ * Boot PROM Test
+ The Boot PROM test insures the Boot PROM is present, and can be read.
+ Failure indicates the Boot PROM was not successfully read due to a
+ hardware problem or due to a conflicts on the Boot PROM address
+ assignment. (Test only applies if the adapter is configured to use the
+ Boot PROM option.)
+
+Failure of a test item indicates a possible system resource conflict with
+another device on the ISA bus. In this case, you should use the Manual Setup
+option to reconfigure the adapter by selecting a different value for the system
+resource that failed.
+
+
+5.2.2 DIAGNOSTIC NETWORK TEST
+
+The Diagnostic Network Test verifies a working network connection by
+transferring data between two CS8900/20 adapters installed in different PCs
+on the same network. (Note: the diagnostic network test should not be run
+between two nodes across a router.)
+
+This test requires that each of the two PCs have a CS8900/20-based adapter
+installed and have the CS8900/20 Setup Utility running. The first PC is
+configured as a Responder and the other PC is configured as an Initiator.
+Once the Initiator is started, it sends data frames to the Responder which
+returns the frames to the Initiator.
+
+The total number of frames received and transmitted are displayed on the
+Initiator's display, along with a count of the number of frames received and
+transmitted OK or in error. The test can be terminated anytime by the user at
+either PC.
+
+To setup the Diagnostic Network Test:
+
+ 1.) Select a PC with a CS8900/20-based adapter and a known working network
+ connection to act as the Responder. Run the CS8900/20 Setup Utility
+ and select 'Diagnostics -> Network Test -> Responder' from the main
+ menu. Hit ENTER to start the Responder.
+
+ 2.) Return to the PC with the CS8900/20-based adapter you want to test and
+ start the CS8900/20 Setup Utility.
+
+ 3.) From the main menu, Select 'Diagnostic -> Network Test -> Initiator'.
+ Hit ENTER to start the test.
+
+You may stop the test on the Initiator at any time while allowing the Responder
+to continue running. In this manner, you can move to additional PCs and test
+them by starting the Initiator on another PC without having to stop/start the
+Responder.
+
+
+
+5.3 USING THE ADAPTER'S LEDs
+
+The 2 and 3-media adapters have two LEDs visible on the back end of the board
+located near the 10Base-T connector.
+
+Link Integrity LED: A "steady" ON of the green LED indicates a valid 10Base-T
+connection. (Only applies to 10Base-T. The green LED has no significance for
+a 10Base-2 or AUI connection.)
+
+TX/RX LED: The yellow LED lights briefly each time the adapter transmits or
+receives data. (The yellow LED will appear to "flicker" on a typical network.)
+
+
+5.4 RESOLVING I/O CONFLICTS
+
+An IO conflict occurs when two or more adapter use the same ISA resource (IO
+address, memory address or IRQ). You can usually detect an IO conflict in one
+of four ways after installing and or configuring the CS8900/20-based adapter:
+
+ 1.) The system does not boot properly (or at all).
+
+ 2.) The driver can not communicate with the adapter, reporting an "Adapter
+ not found" error message.
+
+ 3.) You cannot connect to the network or the driver will not load.
+
+ 4.) If you have configured the adapter to run in memory mode but the driver
+ reports it is using IO mode when loading, this is an indication of a
+ memory address conflict.
+
+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
+before loading the driver again.
+
+When manually configuring the adapter, keep in mind the typical ISA system
+resource usage as indicated in the tables below.
