Internal Ethernet controller
All ThinkPad's produced the last several years have one of three Ethernet controllers integrated.
The Ethernet controller is located on either a MiniPCI card or Communications Daughter Card, or integrated on the systemboard.
3COM 10/ 100 Ethernet Mini PCI Adapter With 56k Modem
IBM Partnumber: 22P7594
This adapter is located on a MiniPCI card, together with a 3Com Modem (for which no Linux driver exists). This card is only supported on the following machines:
- A20m, A20p
- A21m, A21p, A21e
- T20, T21, T22, T23
- X20, X21
Chipset: Various Intel Mobile Ethernet chips
The e100 driver is the suggested driver, but 'eepro100' should also work.
On older ThinkPad's this is implemented on a MiniPCI card, on newer ThinkPad's this is integrated into the systemboard.
This chip is integrated into the systemboard.
Note: This chip support Auto-MDX, meaning you will never need a crossover ethernet cable.
