Here is a blurb from the W98 Resource kit talking about how to enable ACPI (on computers that support it) after 98 is installed as well as at install time.....<br><br>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.<br>To install ACPI<br> 1. Flash the BIOS to the latest rev.<br> 2. Run Regedit.<br> Under HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Detect, add a String value called ACPIOption, and set it to 1.<br> 3. In Control Panel, click Add/Remove Hardware and have it run full detection.<br> <br>To remove ACPI support, perform steps 1 through 3, but set ACPIOption to 2. The settings for ACPIOption are as follows:<br>0 (or not present) – Detect only ACPI BIOSs on good list.<br>1 – Detect any ACPI BIOS.<br>2 – Do not detect ACPI BIOSs (remove support if installed).<br>Alternatively, you can enable ACPI support at setup time using the following command line:<br> <br>setup /p J<br> <p>Doug<br><a href=mailto:dxd_2000@yahoo.com>dxd_2000@yahoo.com</a><br><a href= > </a><br>
