40 4.2 Compiling the driver to support memory mode
46 5.2.1 Diagnostic Self-Test
66 The CS8900-based ISA Ethernet Adapters from Cirrus Logic follow
67 IEEE 802.3 standards and support half or full-duplex operation in ISA bus
69 in 16-bit ISA or EISA bus expansion slots and are available in
70 10BaseT-only or 3-media configurations (10BaseT, 10Base2, and AUI for 10Base-5
73 CS8920-based adapters are similar to the CS8900-based adapter with additional
85 or loaded at run-time as a device driver module.

107 ------------------------
111 * Cirrus Logic LAN (CS8900/20-based) Ethernet ISA Adapter
113 * IBM or IBM-compatible PC with:
115 * 16 bytes of contiguous IO space available between 210h - 370h
116 * One available IRQ (5,10,11,or 12 for the CS8900, 3-7,9-15 for CS8920).
118 * Appropriate cable (and connector for AUI, 10BASE-2) for your network
125 * CS8900/20 Setup Utility (DOS-based)
135 --------------------------
154 Both the CS8900 and CS8920-based adapters can be configured using parameters
155 stored in an on-board EEPROM. You must use the DOS-based CS8900/20 Setup
159 configuration parameters on the command-line to override the EEPROM's settings
160 or for interface configuration when an EEPROM is not used. (CS8920-based
163 Since the CS8900/20 Setup Utility is a DOS-based application, you must install
164 and configure the adapter in a DOS-based system using the CS8900/20 Setup
166 installing a CS8900-based adapter and the default configuration is acceptable.)
169 2.1. CS8900-based Adapter Configuration
170 ---------------------------------------
172 CS8900-based adapters shipped from Cirrus Logic have been configured
175 Operation Mode: Memory Mode
180 Transmission Mode: Half-duplex
182 Media Type: Autodetect (3-media cards) or
183 10BASE-T (10BASE-T only adapter)
190 2.2. CS8920-based Adapter Configuration

193 CS8920-based adapters are shipped from Cirrus Logic configured as Plug

220 be specified as command-line arguments to the load command. This facility
232 io=### - specify IO address (200h-360h)
233 irq=## - specify interrupt level
234 use_dma=1 - Enable DMA
235 dma=# - specify dma channel (Driver is compiled to support
237 dmasize=# (16 or 64) - DMA size 16K or 64K. Default value is set to 16.
238 media=rj45 - specify media type
242 duplex=full - specify forced half/full/autonegotiate duplex
245 debug=# - debug level (only available if the driver was compiled
250 a) If an EEPROM is present, any specified command-line parameter
254 b) The "io" parameter must be specified on the command-line.
271 e) The minimum command-line configuration required if an EEPROM is
279 used with no EEPROM or command-line argument).
284 * CS8900 defaults to half-duplex if not specified on command-line
285 * CS8920 defaults to autoneg if not specified on command-line
313 j) The cs89x0 supports DMA for receiving only. DMA mode is
315 with large ping packets consumes 82% of its CPU capacity in non-DMA
316 mode. With DMA this is reduced to 45%.
318 k) If your Linux kernel was compiled with inbuilt plug-and-play

333 mode may be selected by providing the kernel with a boot option

348 The DMA Rx buffer size is hardwired to 16 kbytes in this mode.
349 (64k mode is not available).

406 * Select 'Self-Test' to test the adapter's basic functionality.
410 5.2.1. Diagnostic Self-test
413 The diagnostic self-test checks the adapter's basic functionality as well as
414 its ability to communicate across the ISA bus based on the system resources
420 accessed in IO mode, and that the IO base address is correct.
425 mode and that the range of memory addresses assigned does not conflict
442 * Internal Loop-back Test
471 This test requires that each of the two PCs have a CS8900/20-based adapter
484 1. Select a PC with a CS8900/20-based adapter and a known working network
486 and select 'Diagnostics -> Network Test -> Responder' from the main
489 2. Return to the PC with the CS8900/20-based adapter you want to test and
492 3. From the main menu, Select 'Diagnostic -> Network Test -> Initiator'.

505 The 2 and 3-media adapters have two LEDs visible on the back end of the board
506 located near the 10Base-T connector.
508 Link Integrity LED: A "steady" ON of the green LED indicates a valid 10Base-T
509 connection. (Only applies to 10Base-T. The green LED has no significance for
510 a 10Base-2 or AUI connection.)

521 of four ways after installing and or configuring the CS8900/20-based adapter:
530 4. If you have configured the adapter to run in memory mode but the driver
531 reports it is using IO mode when loading, this is an indication of a
535 diagnostic self-test. Normally, the ISA resource in conflict will fail the
536 self-test. If so, reconfigure the adapter selecting another choice for the
543 diagnostics self-test to ensure the new configuration is free of conflicts
