No, I have ACPI compilant PC in System config table. I wonder that W2K disabled that settings "forever" (until next fresh reinstall) after disabling ACPI in BIOS. It happened me once when my computer crashed when resuming from Suspend mode and then W2K disabled Suspend tab in APM config dialog. Forever :-((
I searched for some tweak utility, that should restore Hibernate and Suspend dialogs, but I couldn't find anything.
Stupid W2K, but they are sooooo stable
