I have uploaded the driver for the Chipset From their own site. But you will need a strong connection and it may take a few tries. A better host is needed. (FIC K8MC51G). Info:
This driver file is for the FIC K8MC51G nVidia nForce chipset drivers - RAID, SMBus, Ethernet - common in the eMachines and Gateway towers with DDR and SOC.754 AMD K8. I have tested these drivers on the FIC K8MC51G inside an eMachines T3410 tower running Windows XP Home Edition SP3 and thus far have been satisfied.
