Appendix C Enabling Acpi - Fujitsu Stylistic 2300 Technical Reference Manual

Appendix C
Enabling ACPI
The Stylistic 2300 pen tablet BIOS supports ACPI (under Windows 98 only); however, the system is
shipped with APM enabled as the factory default power management interface. Due to limitations with
the implementation of ACPI in the current release of Windows 98, APM is the recommended setting.
These instructions are primarily provided for testing purposes.
Note: Suspend-to-Disk operation is not supported by the current release of Windows 98 using ACPI mode.
Microsoft intends to support Suspend-to-Disk operation in ServicePack 1 for Windows 98 which is not
available at the time of this writing.
To use ACPI, you must edit the registry and enable ACPI detection on the pen tablet as described in the
following procedure:
1. Attach a mouse to your system. You must perform this procedure using a mouse. (A keyboard is also
helpful, but is not required.)
2. From the start menu, choose Run, type Regedit, and choose OK to open the Registry Editor.
3. In the Registry Editor, open the directory:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Detect.
4. From the Edit menu, choose New, DWORD Value. A new value appears in the registry.
5. Select the new value and choose Modify from the Edit menu. Name the new value ACPIOption and set
the value to 1H.
6. In the Registry Editor, open the directory: HKEY_LOCAL_MACHINE\Enum\USB\ROOT_HUB\
PCI&VEN_8086..., and change the value of ConfigFlags from 00 00 00 00 to 00 00 01 00. (This is
necessary to ensure proper operation when using Suspend-to-RAM mode.)
7. Close the Registry Editor.
8. Open Control Panel and choose Add New Hardware. Choose Yes when prompted to allow Windows
98 to detect new hardware.
9. When prompted, choose Yes to restart your system.
When your system restarts, Windows 98 will detect and enable the ACPI in the BIOS and will run using
ACPI. To disable ACPI and enable APM, follow the procedure above and set the ACPIOption value to 2H
(instead of 1H) when you perform step 5.
