From d79a5f80dc1153d3f637dfcf3808066414fbb51a Mon Sep 17 00:00:00 2001 From: Carlos Corbacho Date: Fri, 19 Oct 2007 18:51:27 +0100 Subject: x86: Force enable HPET for CK804 (nForce 4) chipsets This patch adds a quirk from LinuxBIOS to force enable HPET on the nVidia CK804 (nForce 4) chipset. This quirk can very likely support more than just nForce 4 (LinuxBIOS use the same code for nForce 5), and possibly nForce 3, but I don't have those chipsets, so cannot add and test them. Tested on an Abit KN9 (CK804).
