Power Management using ACPI (PC98)

My PC's motherboard (AOpen 6XB Plus - the current AOpen BX chipset one) supports ACPI power management. Win 98 enables ACPI with only a few tested motherboards (I can't find out which ones but it's not enabled automatically with mine). The instructions in here:
tell you how to enable ACPI for a motherboard that supports it (most current ones do).

I followed the instructions for enabling acpi after already installed Win98 following the instuctions in the above URL, i.e. defining a new field in the registry and running PnP hardware detection. Anyway - zilch, nothing happens. Acpi is not detected and my PC appears the same after as it was before.

How can I get ACPI working? I'd like to have my pc go on low power standby with the cpu fan off as the ACPI standard says it should. Currently I'm getting just APM level standby. Any help would be much appreciated

First of all, find out if PnP bios or ACPI bios is flashed in your system.  At Bios menu, it'll say so.  Most newer motherboard DID NOT came with ACPI bios, and lots of ACPI bios from varies manufacturers are still in BETA.  (My Asus P2B came with PnP bios and had to be flash with ACPI bios to get it to work)

Make sure the registry key is of correct value, and if you still can't get it to auto detect, try deleting the PnP bios related items under system devices.
