From 1602dd5fddf3ada03508738218d760a7544ace50 Mon Sep 17 00:00:00 2001 From: Morgan Tsai Date: Mon, 29 Oct 2007 21:00:14 +0000 Subject: Thanks to the great efforts of Morgan Tsai of SiS we support the SiS966 southbridge now: From: Morgan Tsai It supports SiS761GX / SiS966 chipset, only for AMD K8 platform so far. Due to integrated VGA sharing system memory, some code in southbridge folder have to init northbridge. Copyright (C) 2007 Morgan Tsai Copyright (C) 2007 Silicon Integrated Systems Corp.
