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
<ulink url="http://ftp.kernel.org/pub/linux/kernel/">official kernel ftp site</ulink>
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
<ulink url="http://www.tldp.org/">Ethernet HOWTO</ulink> and
<ulink url="http://www.tldp.org/">Networking HOWTO</ulink> available from
Linux Documentation Project (LDP).
</para>
<para>
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
<filename>sis900.c</filename> and <filename>sis900.h</filename>
copied into <filename class="directory">/usr/src/linux/drivers/net/</filename> first.
There are two alternative ways to install the driver
</para>
<sect1>
<title>Building the driver as loadable module</title>
<para>
To build the driver as a loadable kernel module you have to reconfigure
the kernel to activate network support by
</para>
<para><screen>
make menuconfig
</screen></para>
<para>
Choose <quote>Loadable module support ---></quote>,
then select <quote>Enable loadable module support</quote>.
</para>
<para>
Choose <quote>Network Device Support ---></quote>, select
<quote>Ethernet (10 or 100Mbit)</quote>.
Then select <quote>EISA, VLB, PCI and on board controllers</quote>,
and choose <quote>SiS 900/7016 PCI Fast Ethernet Adapter support</quote>
to <quote>M</quote>.
</para>
<para>
After reconfiguring the kernel, you can make the driver module by
</para>
<para><screen>
make modules
</screen></para>
<para>
The driver should be compiled with no errors. After compiling the driver,
the driver can be installed to proper place by
</para>
<para><screen>
make modules_install
</screen></para>
<para>
Load the driver into kernel by
</para>
<para><screen>
insmod sis900
</screen></para>
<para>
When loading the driver into memory, some information message can be view by
</para>
<para>
<screen>
dmesg
</screen>
or
<screen>
cat /var/log/message
</screen>
</para>
<para>
If the driver is loaded properly you will have messages similar to this:
</para>
<para><screen>
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
</screen></para>
<para>
showing the version of the driver and the results of probing routine.
</para>
<para>
Once the driver is loaded, network can be brought up by
</para>
<para><screen>
/sbin/ifconfig eth0 IPADDR broadcast BROADCAST netmask NETMASK media TYPE
</screen></para>
<para>
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
<ulink url="http://www.tldp.org/">Networking HOWTO</ulink>.
</para>
<para>
The link status is also shown by kernel messages. For example, after the
network interface is activated, you may have the message:
</para>
<para><screen>
eth0: Media Link On 100mbps full-duplex
</screen></para>
<para>
If you try to unplug the twist pair (TP) cable you will get
</para>
<para><screen>
eth0: Media Link Off
</screen></para>
<para>
indicating that the link is failed.
</para>
</sect1>

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.
_________________________________________________________________
