WinXP Home Edition - Event Viewer - System Error ACPI
Posted on 2002-06-30
AMLI: ACPI BIOS is attempting to write to an illegal IO port address (0xcf8), which lies in the 0xcf8 - 0xcff protected address range. This could lead to system instability. Please contact your system vendor for technical assistance.
Everything on my system seems be working fine yet I still keep getting this error. I was able to find this exact error message listed on Microsoft Knowledge Base but not how to fix it. In checking on system properties.. device manager, Microsoft ACPI - Compliant System
device status message states: This device is working properly.
My mother board is a ASUS Cuv4x and I have the very latest 4in1 drivers installed. Power Management is disabled in the bios letting WinXP handle it. A Zip drive and scanner are on my USB ports with the latest drivers installed. The USB Root Hub - Power Management, "Allow the computer to turn off this device to save power" is disabled. For my power management I only have my monitor standby setting enabled. Everything else is turned off... so I see no reason to enable power management on the USB ports.
