Running Windows Me on a Compaq Presario model 7470. The item, "System board extension for ACPI BIOS", (Device manager, System devices) has a yellow exclamation point in front of it. What does this mean? I normally use 256 MB RAM (2-128 MB sticks). If I remove one stick the error ( yellow exclamation point) goes away. Either stick works OK., so it's not a memory module fault.
What's the problem?
