From 27e468597315e5ce078fdd39856b7954b639183a Mon Sep 17 00:00:00 2001 From: Krzysztof Helt Date: Sun, 8 Jun 2008 13:47:02 +0200 Subject: [PATCH] PCI: unhide the SMBus on the Compaq Deskpro EN MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This patch unhides the SMBus on Compaq Deskpro EN SFF P667 with the Intel 815E chipset. Unhiding it reveals a THMC51 hardware monitoring chip. Jean Delvare has checked that this machine has no ACPI magic touching the SMBus nor the hardware monitoring chip, so this should be safe. The patch was tested on Fedora Core 9 with 2.6.25.4 kernel.
