Will Linux-ACPI one day address this problem so a user doesn't need to invoke something like "setpci -v -H1 -s 0:0.0 52=$(printf %x $((0x $(setpci -H1 -s 0:0.0 52) | 0x80)))" to enable proper power saving? My fear is just one day I buy a new mainboard and there's no appropriate setpci-command on the Powersaving Howto and Linux-ACPI doesn't enable C2-powersaving if the mainboard doesn't do it first... Why the f*** do mainboard makers not offer a BIOS switch to enable this? Besides the lack of out-of-the-box C2-level ACPI just runs fine. I guess if new generation mainboards (KT400 and up) would better handle K7 power saving we wouldn't need the Powersaving Howto, right? regards Malte (SuSE 9.0,Linux 2.4.21+ACPI 20030619 on Elitegroup K7VZA Rev3.0 + AMD Duron 750 (old spitfire core)) ------------------------------------------------------- This SF.Net email is sponsored by The 2004 JavaOne(SM) Conference Learn from the experts at JavaOne(SM), Sun's Worldwide Java Developer Conference, June 28 - July 1 at the Moscone Center in San Francisco, CA REGISTER AND SAVE! http://java.sun.com/javaone/sf Priority Code NWMGYKND
