If it does, then the motherboard mfg. must have slacked; also check for BIOS updates for your motherboard. > -----Original Message----- > From: Jarek Zuk [mailto:j.zuk-QYlicCNJNu5TzFIbWlesCw@public.gmane.org] > Sent: Thursday, April 15, 2004 07:03 PM > To: 'Dino Klein' > Cc: acpi-devel-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org > Subject: Re: [ACPI] ACPI wake up event (alarm) > > > I have Intel 845 .
