My RTL8139 card bit the dust this past weekend so I have been stuck without a working ethernet card. I had been using the RTL8139 because the built-in network adapter is a nForce 590i MCP55. The MCP55 ethernet adapter has up until now not worked at all under osx (at least with my gigabyte motherboard).

The attached driver is a combination of planetbeing's nForce4 0.3c driver and the forcedeth 0.61 driver from linux 2.6.27. In theory the attached driver should work with any of the network adapters supported by the forcedeth 0.61 driver (from the nForce1 to the MCP79) but it has so far only been tested with my MCP55. This driver can be considered a replacement for both forcedeth.kext and nForceEthernet.kext. Please let me know how well this works (or doesn't work for that matter).

This driver is being released under the GPL. For now the source code will be available upon request. I will post the source code here once I have had a chance to clean up the code and run further tests.

The original nForce4 driver is posted here: nForce4 LAN driver

0x0ab010de, 0x0ab110de, 0x0ab210de, 0x0ab310de

Updates:
- removed rx/tx checksum overrides. Should work with more cards out of the box now.
- [0.61.1alpha_osx]added support for sleep/wake functions.
- [0.61.2alpha_osx]added OptimizationMode option (0 = throughput, 1 = cpu). CPU optimization is the default since it appears to works better with some devices (my MCP55). The option can be set in the Info.plist.
- [0.61.3alpha_osx]renamed to nForceLAN.kext and some small bug-fixes.

enjoy!

Looks like this has potential to be the best nforce LAN driver yet. Visit this thread on InsanelyMac to try it out and leave feedback:

Thanks for the link Voyn1x!! If I can get my built in ethernet working then I'll be a very happy chappy.

Works on my setup

Built in lan never worked before with any of the forcedeth kexts, but this new nForceLan kext works a treat on mine: 10de:0373 nVidia Corporation MCP55 Dual Gigabit Ethernet with Vitesse chipset. I urge everyone with built in lan to try this out and leave feed back for eno over at insanelymac.

From the second I load it, it hogs my kernel_task, tried al the kexts but same thing. I'm back to the standard forcedeth for now.

Asus A8N-SLI nForce4 SLI

Hmmm I have the Asus A8N-SLI Premium and an Asus A8N-E FM/S. Both are working fine with the forcedeth-v driver. But I'm using skge.kext on the Premium, it has two LAN ports. More interesting would be a new nForce SATA driver. It's so slooow... (sigh).

Its work for me.

MB: m2n-e

I deleted old forcedeth kext and copy nForceLan.kext and reboot, remove power cord, wait 30sec e power on.

Good Job.

The only component i never got to work is my RTL8201N (0x07dc10de) ethernet. Forcedeth 0.3 would just give me an inverse MAC address, and when that was fixed it still wouldn't settle with the router IP i was assigning.

Same situation happens with 0.6alpha.
