Appendix B Enabling Acpi - Fujitsu Stylistic 3400 Technical Reference Manual

Appendix B
Enabling ACPI
The Stylistic 3400 pen tablet BIOS supports ACPI (under Windows 98); however, Windows 98 systems are
shipped with APM enabled as the factory default power management interface. ACPI is not available in
Windows NT 4.0 systems. Due to limitations with the implementation of ACPI, APM is the
recommended setting.
To use ACPI on Windows 98 systems, 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
to detect new hardware.
9. When prompted, choose Yes to restart your system.
When your system restarts, Windows 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.
