SYMPTOMS
After you start Windows 98 on a computer that conforms to the Advanced Configuration and Power Interface (ACPI) specification, several hardware devices may not function and may appear in Device Manager as having problems, with the following error messages:

This device is not working properly because the BIOS in your computer is reporting the resources for the device incorrectly (Code 9).

Contact your computer manufacturer to get an updated BIOS for your computer.

This device is either not present, not working properly, or does not have all the drivers installed (Code 10).

Try upgrading the device drivers for this device.

The drivers for this device are not installed (Code 28). To reinstall the drivers for this device, click Reinstall Driver.

This device is causing a resource conflict. (Code 15.)

To resolve the conflict, click Hardware Troubleshooter and follow the instructions in the wizard.



CAUSE
The Windows 98 ACPI driver (Acpi.sys) does not properly execute the release of the ACPI Global Lock when the Global Lock is explicitly released by ACPI Source Language (ASL) code.

MORE INFORMATION
GlobalLock is a feature of ACPI that allows protection of resources between ASL code executed by the operating system and the legacy BIOS/SMI environment. GlobalLock can be treated as a mutex that can be explicitly acquired and released. The original release of Windows 98 does not execute the explicit release when encountered in the ASL code. Therefore, once the GlobalLock mutex is acquired, the operating system never releases. This causes a number of problems, including exclamation points on all the devices that require access to a resource that needs to be protected by GlobalLock.

Note that the implicit GlobalLock accesses work correctly in the original release of Windows 98. An implicit GlobalLock is tied directly to the access of a field or index field of an operation region. It is carried out implicitly when an the object is accessed.
