	Summary:
	Enabling ACPI for Testing and Development with Windows 
	98. The following instructions will allow any OEM to 
	enable ACPI on its systems for testing with Windows 98.

	Windows 98 *doesn't* automatically install ACPI when 
	it is installed. During Windows 98 Setup, ACPI is 
	installed only on systems that are listed on the 
	retail compact disc as good ACPI systems. However, 
	if you have had the system BIOS updated to a fully 
	functioning ACPI BIOS, you can have ACPI installed by 
	using the following procedure.

	Solution 1:
	To enable ACPI suport at setup time using the 
	following command line:

		setup /p J

	Solution 2:
	To enable ACPI after Windows 98 is installed:

	1.	run Regedit and go to the following key in the 
		registry: 

		HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\
			Current Version\Detect

	2.	Create a new DWORD value called "ACPIOption" 
		and set it equal to 1.

	3.	In Control Panel, run Add New Hardware and choose 
		hardware detection. ACPI should be detected and 
		installed.

	4.	After the system is rebooted, all ACPI-enumerated 
		devices will be set up again.



	Troubleshooting:
	To remove ACPI support, perform steps 1 through 3, but 
	set ACPIOption to 2.

	The settings for ACPIOption are as follows:

	0 (or not present)	Detect only ACPI BIOSs on good
				list.

	1			Detect any ACPI BIOS.

	2			Do not detect ACPI BIOSs (remove
				support if installed).
