This document contains instructions on installing Linux driver and adjusting speed for the series of RTL8139(A/B/C/8130) Network Adapter Installing Driver: (1.) Kernel Had Supported Driver: Check the directory " /lib/modules/¡K./net " if you could find "rtl8139.o" Your kernel had supported RTL8139 series. You could easy use "linuxconf" to setup your card. If you don't like linuxconf, you also could use "modprobe rtl8139" and "ifconfig up eth0" to load module. If your driver load properly, your "/etc/conf.modules" should include line of "alias eth0 rtl8139". (2.) Kernel Don't Support Driver: If your kernel doesn't support RTL8139 series, you should compiler driver by yourself. Please contact http://www.scyld.com/network/rtl8139.html to get source code. The compiler command is located on the end of source code. Maybe like "gcc -DMODULE -Wall -Wstrict-prototypes -O6 -c rtl8139.c". If you couldn't compiler success, maybe you should refer to error message and copy library or head file to Linux. Adjust Speed: (1.) Adjusting speed: Driver is designed with the gold that no options should be needed in most environment. However not all cards and networks can be automatically configured, thus allow operational parameters to be modify when they are loaded as module. Typically the following variables may be set: insmod rtl8139 options=0x40 Hex Decimal Meaning 0x10 16 ¡K..Force Full-Duplex operation (must be used with 0x20 or 0x40) 0x20 32 ¡K..Force 100mbps-only operation 0x40 64 ¡K..Force 10mbps-only If loading as a module and configured /etc/conf.modules alias eth0 rtl8139 options options=0x40 Look weird like that but I believe that works. That's what I got out of the documentation. It seems like the options are supported in the module. If not, you'll need to download ftp://ftp.scyld.com/pub/diag/rtl8139-diag.c Compiling syntax is at the end. Run: "rtl8139-diag -F 10baseT-HD" That will force it to 10Mbps at half-duplex. If you want full-duplex change it to 10baseT-FD. You'll need a switch for full-duplex. Once you establish that it works, you can write the setting to the EEPROM with "rtl8139-diag -w".

After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
