I need to know how to set my Intel 82557 Ethernet Pro 100 NIC to auto/auto. It probably should be, but I have it hooked to a 10mbit port and I do not get any network activity on the NIC. I can plug another computer into the same port with a 10/100 NIC set to auto/auto and get a 10mbit connection. That same computer will connect at 100mbit on a port that is setup at 100. I need to set my linux Mandrake 9 box to either 10/half or auto/auto. How do I do this?

Assuming the eepro100 driver was compiled as a module, you need to add an option to the line that loads this driver in /etc/modules.autoload (Your distro may have this in a different file) options for the eepro100 are: 0x10 for 10half 0x20 for 10full 0x100 for 100half 0x200 for 100full so you line in this file for 10half should look like: eepro100 options=0x10 Intel also has eepro drivers for linux but there method of changing speed is different, instead of options= they have e100_speed_duplex= with the following options: 0 for auto 1 for 10H 2 for 10F 3 for 100H 4 for 100F

Thanks, although the file modules.autoload did not exist on my system, I did find modules.conf. Added the line eepro100 options-0x10 to it and saved it, rebooted and still no network access. I haven't tried the Intel drivers. I did go to the site to look for them, but really didn't find 82557 drivers, they were kind of vague about which ones to get. Thanks again for your help. I will try the drivers and tell you how it comes out.

Here is the line from my modules.conf file: alias eth0 eepro100 NOTE: This may be different for your linux distro. 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 …..Force Full-Duplex operation (must be used with 0x20 or 0x40) 0x20 32 …..Force 100mbps-only operation 0x40 64 …..Force 10mbps-only try adding line: options options=0x40

Also try ethtool, I just remembered that lost little util. that can do all the adjustments you may ever require. I recommend installing if it not in your linux distro.
