ACPI in Windows 7

[joyofjoy]

Hey,

I need to know if it is possible to turn off ACPI (Advanced Configuration and Power Interface) in Windows 7. I know this was possible in XP and wonder if im able to do it with 7.

Your help will be greatly appreciated!

Just checked in my 7 installation, ACPI x64 computer driver didn't have any other compatible options, so I guess the answer is no.

Joyofjoy,

Just so you're aware, Microsoft does have an official Windows 7 RC Support Forum located here tinyurl.com/9fhdl5. It is supported by product specialists as well as engineers and support teams. You may want to check there for addtional support and feedback.

Based on what I've read about people installing Windows 7 on some pretty ancient platforms, it sounds like Windows 7 can be installed on non-ACPI compliant systems. At the same time, much like Mic, I don't see any options in Device Manager. If Windows 7 *does* support non-ACPI hardware, it is possible that this may have to be done at install time. If this is true, disabling ACPI in your BIOS and performing a repair install should achieve what you want.

Just brainstorming here, but I think it is safe to assume the 32-bit version does support non-ACPI compliant hardware, it is very possible that the 64-bit version does not. Something else to think about.

However, I have to ask you... what's the issue? Maybe it is a problem we can solve for you without messing with ACPI?

It would be awesome if I could get Win7 on my P2 350, but after a couple days of trying and googling I didn't figure out how to do it. It was an ACPI problem.

Joyofjoy, I don't know if it's possible to turn off ACPI in Windows 7, but you may be able to suspend the thread "ACPI.SYS!" in "System" process using process explorer. that may give you the desired effect you're looking for.??

Hmmm.... I'm not really 100% certain of this (or how it applies/works for Windows 7) but i'll toss the idea out as you might want to take a look or google it further....

I think that in order to install Windows (any version of Windows) on non ACPI compliant hardware, requires Windows is installed with a compatible and similar non-ACPI version of the Hardware Abstraction Layer (hal).

You might try
> Searching in your Windows directory for search pattern hal*.dll
> Then see if any of the hal*.dll's provided are intended to support non ACPI hardware
> I would guess if no HAL definition exists supporting non-ACPI, it's not possible

Note: All of the possible hal*.dll's available, get installed under the name hal.dll
