I'm no expert at all, but you have no responses yet... So, any hints in dmesg? On my PIII 500 mhz sarge box, I get this: ACPI disabled because your bios is from 1999 and too old You can enable it with acpi=force And sure enough, it doesn't like to run with acpi=force, so I've left it alone. Perhaps you could remove acpi and load apm instead? Good luck, Ralph -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
