68This document describes the revision 1.06 and 1.07 of SiS 900/7016 Fast Ethernet
69device driver under Linux. The driver is developed by Silicon Integrated
70System Corp. and distributed freely under the GNU General Public License (GPL).
71The driver can be compiled as a loadable module and used under Linux kernel
72version 2.2.x. (rev. 1.06)
73With minimal changes, the driver can also be used under 2.3.x and 2.4.x kernel
74(rev. 1.07), please see
75<xref linkend="install"/>. If you are intended to
76use the driver for earlier kernels, you are on your own.
77</para>
78
79<para>
80The driver is tested with usual TCP/IP applications including
81FTP, Telnet, Netscape etc. and is used constantly by the developers.

319Silicon Integrated System Corp. is cooperating closely with core Linux Kernel
320developers. The revisions of SiS 900 driver are distributed by the usuall channels
321for kernel tar files and patches. Those kernel tar files for official kernel and
322patches for kernel pre-release can be download at
323<ulink url="http://ftp.kernel.org/pub/linux/kernel/">official kernel ftp site</ulink>
324and its mirrors.
325The 1.06 revision can be found in kernel version later than 2.3.15 and pre-2.2.14,
326and 1.07 revision can be found in kernel version 2.4.0.
327If you have no prior experience in networking under Linux, please read
328<ulink url="http://www.tldp.org/">Ethernet HOWTO</ulink> and

330Linux Documentation Project (LDP).

334The driver is bundled in release later than 2.2.11 and 2.3.15 so this
335is the most easy case.
336Be sure you have the appropriate packages for compiling kernel source.
337Those packages are listed in Document/Changes in kernel source
338distribution. If you have to install the driver other than those bundled
339in kernel release, you should have your driver file
340<filename>sis900.c</filename> and <filename>sis900.h</filename>
341copied into <filename class="directory">/usr/src/linux/drivers/net/</filename> first.
342There are two alternative ways to install the driver
