The VT 8237 drivers can be downloaded from viaarena, but I have a link for easier access for you. I used to have a Soyo with the same Via KT600 and an earlier KLE266 chipset. The last set I used were the 4.53. Here is a link for an assortment of 4 in 1 drivers: http://downloads.guru3d.com/download.php?id=16
Any idea what the Northbridge is? (CLE266, KN400, KM400, K8M800, PM800, CN400, VN800, etc)
