Here are the 2 ACPI tables that I load with grub2 for my mod -

@Damnation

Here it is.

Be careful, because your XP will not longer start if something goes wrong

No problems thus far, but the DSDT is unmodified, can you make one for the CPU SSDT too? that's where all the changes are made.

@Damnation

They are both in this acpi.reg file: DSDT and SSDT2.

It should work.

My compi refuses to boot, after I offered him this acpi.reg file,

which simple means, that it is loaded.

The only problem that I had before was, when I take the DSDT direct out of the Bios.

With the acpi tables taking from running windows, all is nice now.

Everything works for me, even with acpi.reg from other compi

PS: By the way I noticed, that RWEverything reads out the loaded ACPI tables and not them from Bios.

So, with RW Everything you can make a very quick check, if the tables are loaded.

@Dietmar

OK, I checked in the registry and I see that the keys were applied, however XP seems to just be ignoring these keys entirely and my CPU still runs at 140W and DSDT is from BIOS.

@Damnation

Make sure, that Secure Boot is disabled in your compi Bios settings.

With Microsoft I think, that then no Acpi Tables are taken from registry, only from Bios

Dietmar

@Dietmar

Yes secure boot is disabled.

@Damnation

Because it works for me on the Asrock z690 Extreme board

and also on the Asrock z370 k6 gaming board,

the only idea that I have is, that some settings on your Bios does not match for to upload those tables

@Dietmar

Moving these keys to CurrentControlSet instead of ControlSet001 results in an A5 BSOD

@Damnation

Exact this happens to me,

when I take the DSDT from the Bios and not from the running XP

Dietmar

@Damnation

Make a new extract of all Acpi files under running Win10 from your compi. Do you have Bios 2.2?

Because from the Asrock Webside I read, that with from Bios 2.10 upward enable AMD CPU fTPM in BIOS default.

Can you disable fTPM in Bios?

 

If not, you can go back to an older Bios, BUT ALWAYS RISK to change something in BIOS.

 

And then try to upload its own dsdt.raw with the asl.exe tool under XP SP3.

Later you can edit a little thing via dsdt.dsl and look, if it is still loaded after reboot with the asl.exe tool

@Dietmar

Yes I have BIOS 2.2

TPM is on with the default settings, but I made sure to switch it off since since I wanted to install Windows 11 in CSM mode on this machine.

@Damnation

Have you tested the DSDT patcher at boottime from @Mov AX, 0xDEAD?

He updated his Tutorial here at MSFN,

now it is much more easier and it works, I tested

Dietmar

@Dietmar

Where can I find this?
