Ethernet Controllers

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, Communications Daughter Card (CDC), or integrated on the systemboard.

3COM 10/100

MiniPCI cards featuring this chip:

• 3Com 10/100 Ethernet Mini-PCI Adapter with 56K Modem

Intel 10/100

Chipset: Various Intel Mobile Ethernet chips
Driver: e100

The 'e100' driver is the suggested driver, but 'eepro100' should also work.

CDC and MiniPCI cards featuring this chip:

• Intel 10/100 Ethernet Mini-PCI Adapter with 56K Modem
• Intel Pro/100 SP Mobile Combo Adapter
• Mini-PCI Ethernet card
• Xircom 10/100 EtherJet Mini PCI Adapter with 56K Modem

In addition, this chip is integrated into select systemboards of the following machines:

• R50, R50p
• T30
• T40, T41p
• X30, X31

Intel 10/100/1000

Driver: e1000

This chip is integrated into select systemboards of the following machines:

• R50, R50p
• T40, T40p, T41, T41p
• X31
• X40

Note: This chip support Auto-MDX, meaning you will never need a crossover ethernet cable.

Broadcom 10/100

Chipset: Broadcom BCM5901
Driver: tg3 or bcm5700

This chip is integrated into select systemboards of the following machines:

• G40, G41
• R40e

Broadcom 10/100/1000

Chipset: Broadcom BCM5751M
Driver: tg3 or bcm5700

This chip is integrated into select systemboards of the following machines:

• R52
• G41
• T43, T43p
• X41
