| |
The amd74xx IDE driver in 2.5.59 has support for the nforce IDE controller, but not explicitly for the nforce2 IDE controller (which has a different PCI ID, which is in the kernel already). I'm not sure if the nforce and nforce2 controllers are identical, but I made a small patch that made the amd74xx driver recognize the nforce2 IDE, and it boots for me, seems to work fine, as my drives were tuned to their highest transfer rate automatically (udma5).
I don't know if this patch is proper or correct, but it Works for Me [tm]. Patch is attached.
