@Mov AX, 0xDEADIs there a safe space to add assembly code in existing dll file? I tried patching two new subroutines to an empty 0000000 block at the end of the file, but it does not like it. Windows restarts a few seconds after loading with this patch.

I do not remember having those on mine. Only 7E c0000005 and 05 0000011 with unmodified acpi. XP 7777v4 looks good, updated to newest firmware, tested on Gigabyte, B450, with AGESA 1.2.0.6 B

@DietmarIt's fine. Official CAT specification is usually for 100m length, and is expected to be used in server rooms, so interference "noise" from other network cables, etc... Unofficial, I have 15m of cat3 in wall, running 1Gigabit no problem. You can use iperf3 to test network connection speed between computer to computer.

@George King has the individually patched tests, maybe he can narrow down which one specifically worked? This one has the original patch from Dietmar and the four experiment tests that we tried and seemed to work. @Damnationhttps://ufile.io/xyabacfm

There is no patched version of the default XP64 NT5.2x64 acpi that I can test with. At least I haven't seen one. I've only seen longhorn 5048 until now. That's why I mentioned my XP results from the patched NT5.1x86 and longhorn acpis. I also have a server 2003 NT5.2x86 install I can test with. I used the older xp 7777v2 to get it to boot for the first time a little while ago to compare a nvme driver that didnt work in 5.1x86 but works in 5.2x86. I'm assuming a 5.2x86 acpi compile would have the same issue, but I can give it a try to see. I haven't played with setting up the compiler... Is a 5.1x64 compile possible?

@Damnation Looks like I spoke too soon. More testing, this acpi adds a restart bug. After windows turns off in the restart cycle, it never comes back. Have to physically push the restart button. I had this problem before when a PS2 keyboard was attached and no acpi would fix it. But in this case the PS2 is not being used. USB only. All other acpis that boot do not have restart issue when PS2 is not used: x64 5048, x86 5048, 6666, and 7777 v3.

@Damnation@George King I tried acpi_xp_amd64_forGK_2_7z and it boot fine for me when i replaced acpi on a working system. GA-B450AorusM. Maybe you can try on a different test computer and see if you have better luck? Might be an issue specific to your test motherboard.

KeInitializeSpinLock is in ntoskrn8, KeQueryInterruptTime is not

Feels like a traveling circus, visiting from site to site @Dietmar acpiFREEv3 and acpiFREEv3DDB both work same as before, Giga B450 AorusM, 5.1x86. Did not test 5.2x86. I had it installed before while testing a guess, now trying to copy standard VGA driver from 5.2 to 5.1

tested "acpiV22free" and "acpiV22freeDDBhack" works on Gigabyte B450 Aorus M, on 5.1x86 and 5.2x86
