+Chapter 1. Introduction
+
+ This document describes the revision 1.06 and 1.07 of SiS 900/7016
+ Fast Ethernet device driver under Linux. The driver is developed by
+ Silicon Integrated System Corp. and distributed freely under the GNU
+ General Public License (GPL). The driver can be compiled as a loadable
+ module and used under Linux kernel version 2.2.x. (rev. 1.06) With
+ minimal changes, the driver can also be used under 2.3.x and 2.4.x
+ kernel (rev. 1.07), please see Chapter 5. If you are intended to use
+ the driver for earlier kernels, you are on your own.
+
+ The driver is tested with usual TCP/IP applications including FTP,
+ Telnet, Netscape etc. and is used constantly by the developers.
+
+ Please send all comments/fixes/questions to Lei-Chun Chang.
+ _________________________________________________________________
+
+Chapter 2. Changes
+
+ Changes made in Revision 1.07
+
+ 1. Separation of sis900.c and sis900.h in order to move most constant
+ definition to sis900.h (many of those constants were corrected)
+ 2. Clean up PCI detection, the pci-scan from Donald Becker were not
+ used, just simple pci_find_*.
+ 3. MII detection is modified to support multiple mii transceiver.
+ 4. Bugs in read_eeprom, mdio_* were removed.
+ 5. Lot of sis900 irrelevant comments were removed/changed and more
+ comments were added to reflect the real situation.
+ 6. Clean up of physical/virtual address space mess in buffer
+ descriptors.
+ 7. Better transmit/receive error handling.
+ 8. The driver now uses zero-copy single buffer management scheme to
+ improve performance.
+ 9. Names of variables were changed to be more consistent.
+ 10. Clean up of auo-negotiation and timer code.
+ 11. Automatic detection and change of PHY on the fly.
+ 12. Bug in mac probing fixed.
+ 13. Fix 630E equalier problem by modifying the equalizer workaround
+ rule.
+ 14. Support for ICS1893 10/100 Interated PHYceiver.
+ 15. Support for media select by ifconfig.
+ 16. Added kernel-doc extratable documentation.

+ Header file for sis900.c
+

+
+Chapter 5. Installation
+
+ Silicon Integrated System Corp. is cooperating closely with core Linux
+ Kernel developers. The revisions of SiS 900 driver are distributed by
+ the usuall channels for kernel tar files and patches. Those kernel tar
+ files for official kernel and patches for kernel pre-release can be
+ download at official kernel ftp site and its mirrors. The 1.06
+ revision can be found in kernel version later than 2.3.15 and
+ pre-2.2.14, and 1.07 revision can be found in kernel version 2.4.0. If
+ you have no prior experience in networking under Linux, please read
+ Ethernet HOWTO and Networking HOWTO available from Linux Documentation
+ Project (LDP).
+
+ The driver is bundled in release later than 2.2.11 and 2.3.15 so this
+ is the most easy case. Be sure you have the appropriate packages for
+ compiling kernel source. Those packages are listed in Document/Changes
+ in kernel source distribution. If you have to install the driver other
+ than those bundled in kernel release, you should have your driver file
+ sis900.c and sis900.h copied into /usr/src/linux/drivers/net/ first.
+ There are two alternative ways to install the driver
+ _________________________________________________________________
+
+Building the driver as loadable module
+
+ To build the driver as a loadable kernel module you have to
+ reconfigure the kernel to activate network support by
+
+make menuconfig
+
+ Choose "Loadable module support --->", then select "Enable loadable
+ module support".
+
+ Choose "Network Device Support --->", select "Ethernet (10 or
+ 100Mbit)". Then select "EISA, VLB, PCI and on board controllers", and
+ choose "SiS 900/7016 PCI Fast Ethernet Adapter support" to "M".
+
+ After reconfiguring the kernel, you can make the driver module by
+
+make modules
+
+ The driver should be compiled with no errors. After compiling the
+ driver, the driver can be installed to proper place by
+
+make modules_install
+
+ Load the driver into kernel by
+
+insmod sis900
+
+ When loading the driver into memory, some information message can be
+ view by
+
+dmesg
+
+ or
+cat /var/log/message
+
+ If the driver is loaded properly you will have messages similar to
+ this:
+
+sis900.c: v1.07.06 11/07/2000
+eth0: SiS 900 PCI Fast Ethernet at 0xd000, IRQ 10, 00:00:e8:83:7f:a4.
+eth0: SiS 900 Internal MII PHY transceiver found at address 1.
+eth0: Using SiS 900 Internal MII PHY as default
+
+ showing the version of the driver and the results of probing routine.
+
+ Once the driver is loaded, network can be brought up by
+
+/sbin/ifconfig eth0 IPADDR broadcast BROADCAST netmask NETMASK media TYPE
+
+ where IPADDR, BROADCAST, NETMASK are your IP address, broadcast
+ address and netmask respectively. TYPE is used to set medium type used
+ by the device. Typical values are "10baseT"(twisted-pair 10Mbps
+ Ethernet) or "100baseT" (twisted-pair 100Mbps Ethernet). For more
+ information on how to configure network interface, please refer to
+ Networking HOWTO.
+
+ The link status is also shown by kernel messages. For example, after
+ the network interface is activated, you may have the message:
+
+eth0: Media Link On 100mbps full-duplex
+
+ If you try to unplug the twist pair (TP) cable you will get
+
+eth0: Media Link Off
+
+ indicating that the link is failed.
+ _________________________________________________________________
+
+Building the driver into kernel
+
+ If you want to make the driver into kernel, choose "Y" rather than "M"
+ on "SiS 900/7016 PCI Fast Ethernet Adapter support" when configuring
+ the kernel. Build the kernel image in the usual way
+
+make clean
+
+make bzlilo
+
+ Next time the system reboot, you have the driver in memory.
+ _________________________________________________________________
+
+Chapter 6. Known Problems and Bugs
+
+ There are some known problems and bugs. If you find any other bugs
+ please mail to lcchang@sis.com.tw
+
+ 1. AM79C901 HomePNA PHY is not thoroughly tested, there may be some
+ bugs in the "on the fly" change of transceiver.
+ 2. A bug is hidden somewhere in the receive buffer management code,
+ the bug causes NULL pointer reference in the kernel. This fault is
+ caught before bad things happen and reported with the message:
+ eth0: NULL pointer encountered in Rx ring, skipping which can be
+ viewed with dmesg or cat /var/log/message.
+ 3. The media type change from 10Mbps to 100Mbps twisted-pair ethernet
+ by ifconfig causes the media link down.

+
+Chapter 7. Revision History
+
+ * November 13, 2000, Revision 1.07, seventh release, 630E problem
+ fixed and further clean up.
+ * November 4, 1999, Revision 1.06, Second release, lots of clean up
+ and optimization.

+
+ This driver was originally derived form Donald Becker's pci-skeleton
+ and rtl8139 drivers. Donald also provided various suggestion regarded
+ with improvements made in revision 1.06.
+
+ The 1.05 revision was created by Jim Huang, AMD 79c901 support was
+ added by Chin-Shan Li.
