From bb38f3213b6889db9fcdab79086bb860f3a32547 Mon Sep 17 00:00:00 2001 From: Carl-Daniel Hailfinger Date: Sun, 24 Jan 2010 01:40:46 +0000 Subject: [PATCH] Add VIA VT82C686A/VT82C686B detection support to superiotool. This adds an additional requirement to superiotool: libpci. The PCI code is conditional on PCI_SUPPORT. You can set the CONFIG_PCI variable in the Makefile to 'no' to disable it.
