Q: How do I get the intel eepro100 interface to work at 100Mbps full-duplex?

A: If the driver is compiled into the kernel, one must add the following line
to /etc/lilo.conf:

append="ether=0,0,0x30,eth0"

If one is using modules, then add the following to the /etc/conf.modules
file after the "alias eth0 eepro100" line:

options eepro100 options="0x30"

Note: Thanks to Don Holmgren for the answers.

The following are all the options available for the EEPR100 card:

In most cases no transceiver override option need be set. A notable exception
is when connecting to a older ethernet switch that
operates in full-duplex mode but does not do NWay autonegotation. The driver
options flags are recognized:

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

Therefore, option 0x30 == 0x20 + 0x10 ( Force 100mbps-only + Force full duplex)
