The nforce2 onboard ethernet controller works great under linux. nvidia.com's driver page has a driver for it (non-GPL). Also, there is a GPL'd reverse-engineered driver that goes by the name of forcedeth. With 2.4 and newer kernels there is a patch available which offers forcedeth to be compiled into the kernel or as a module. despite a few very minor bugs which won't affect most users, it works like a charm.

Yes, the reverse-eng driver works, but not very good, in the lan i get some transfere rates like 5.5 and 6 Mb (very bad), with my realtek(chipest) NIC, i get 9,8Mb on the lan, and with my 3com NIC's i get more that 11Mb, so i think the driver dont works pretty good, but it's a good reverse eng work! congrats to the ppl o made it! very good job!
