@Dietmar thanks for the tips about the LAN. I installed XP from scratch with the acpiv3DDBhack driver: no issues. Tried also to restart 4 times without any problems. I'm going to prepare another ISO with acpi.sys without hack. Edit: the XP installation with acpi.sys from acpiFREEv3 package stops with the A5 bsod (0x11, 0x08, 0xF6DA2000, 0x20160527)

@Dietmar about the last acpiFREEv3, in my first attempt I simply replaced the driver on the XP working disk: acpi.sys: A5 bsod (0x11, 0x08, 0xB99AD000, 0x20160527) acpiv3DDBhack: worked 3 times on 4 attempts. It failed one time blocking on the XP logo screen with the scroll bar that flows infinitely. I need some time to prepare the XP ISO to try the installation from scratch Thanks for the msvcrt.dll. I'll try with it.

@Dietmar on the target (guest) system the ethernet controller is the intel i219. Since there is no XP driver for it, there is no LAN and I can't set any IP. The ipconfig command doesn't give any IP address. The only way to set it is throught the bios as I already done (192.168.1.3). Here the boot.ini file on target (guest) that hangs the system: [boot loader] timeout=12 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /KERNEL=ntos3.exe /HAL=hal3.dll multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP SP3 DEBUG" /KERNEL=ntos3.exe /HAL=hal3.dll /DEBUG /DEBUGPORT=NET /HOST_IP=192.168.1.1 /HOST_PORT=50000 /ENCRYPTION_KEY=1.2.3.4 /CPUFREQ=3300 /TARGET_IP=192.168.1.3 /BREAK Here the boot.ini that doesn't give errors or results: [boot loader] timeout=12 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect C:\WINDOWS="KDNET FREE" /noexecute=optin /fastdetect /DEBUG /DEBUGPORT=NET /HOST_IP=192.168.1.1 /HOST_PORT=50000 /ENCRYPTION_KEY=1.2.3.4 /CPUFREQ=3300 /TARGET_IP=192.168.1.3 C:\WINDOWS="KDNET Checked" /noexecute=optin /fastdetect /KERNEL=ntos3.exe /HAL=hal3.dll /DEBUG /DEBUGPORT=NET /HOST_IP=192.168.1.1 /HOST_PORT=50000 /ENCRYPTION_KEY=1.2.3.4 /CPUFREQ=3300 /TARGET_IP=192.168.1.3 /BREAK For the "kernel debug" option in WinDBG launched on host, the window displayed already contains the port number (50000) for the "NET" tab. I have to write only the secret key (1.2.3.4). This is what I done for target (guest) and host systems: Host: - installed 'NET Framework 4.0 for Windows XP 32-bit'; - installed 'WindowsXP-KB936929-SP3-x86-DEBUG-symbols-full-ENU-DEBUG' (I had already installed also 'WindowsXP-KB936929-SP3-x86-DEBUG-symbols-update-ENU-DEBUG', I don't know if it is correct), - installed 'x86 Debuggers and Tools-x86_en-us (v6.3.9600.17200)', replacing windbg.exe and dbgeng.dll with patched versions you uploaded. Target (guest): - Boot.ini as above; - Hal3.dll, ntos3.exe, kdnet.dll and kdstub.dll copied in the system32 folder. I also tried with kdnet.dll, kdstub.dll and kdnet10.dll sent me from @Mov AX, 0xDEAD some days ago. I'll try now the last acpi.sys. Edit: both host (msi Q87) and target (GA-H470) have an intel ethernet controller (i217 and i219)

@pappyN4 glad to see you here

@Dietmar after the IP configuration in bios, now WinDBG (from the host system) gives this error never seen before during the debugging attempts: https://pasteboard.co/2JYpHDvVOs9n.png At same time, the target system (GA-H470) hangs as soon as the option "Windows XP SP3 DEBUG [debugger enabled]" is selected in the boot.ini The other boot.ini with the "KDNET" references doesn't give any result (and error).

@Dietmar thanks for your help ;). WinDBG now works but however I'm not able to get debug in my system. I had already tried in Win8.1 thanks to @Mov AX, 0xDEAD. Same situation in XP on an haswell board that I used to install the driver for the intel i217 controller. Here my network configuration: https://pasteboard.co/tzMSZwXIBJIV.png Boot.ini edited as from your instructions. Hal3.dll and ntos3.exe copied in the windows\system32 folder together the minidriver. No debugging when the 'target' machine starts, the system reboots automatically.

@Dietmar could you please report the SHA-1 values for the files to add and replace to obtain a working debug in XP (Windbg.exe included)? I got the error message "windbg.exe is not a valid 32bit application". Thanks.

@Damnation Below the link to download the package containing the tables of my GA-H470: https://anonfiles.com/96y2XaW6x8/GA-H470_zip

Sorry guys for my delay. Today was a busy day and I fear that tomorrow will be the same @daniel_k I just tried the XP installation from a pendrive with the acpi.sys you sent me. Here the bsod code: 0xA5 (0x011, 0x08, 0xF6DA000, 0x20160527) @Dietmar I'll try debugging first on win8 as soon as I'll have some time. But clearly my goal is to get debug in XP @Damnation I got the A5 bsod (0x011, 0x08, 0xFFD4E010, 0x20160527) also in Win7. Not tested in Vista. ------------ P.S.: does deep translator still works for you in XP with Firefox/Basilisk? Edit: deep translator works with NoScript disabled.

@daniel_k @Dietmar I will try new acpi.sys and WinDBG in the afternoon or late in the evening. I don't have time this morning, sorry.

@Dietmar I received the first package from @Mov AX, 0xDEAD but until now I was not able to obtain the connection. Surely, I missed something in the configuration Does Windbg work on your XP system? I had to switch to Win8.1 even if without success.

@Dietmar Tried to install XP from scratch on the GA-H470 board using a thumb drive with the ISO containing the acpi.sys from acpiV22freeDDBhack.7z package. I still got the A5 BSOD (0x03, 0x85B68420, 0xC0140008, 0x494E495F). The same XP ISO installs correctly on the asus prime B250M.

@daniel_k Hi Daniel, also for me it is a pleasure to see you My board is a Gigabyte H470-HD3 About the A5 BSOD, I got a bit different code (0x03, 0xA6671420, 0xC0140008, 0x494E495F) when I used another SSD disk containing the same XP installation.

@Dietmar I'll try to prepare and install a new XP ISO with your last acpiV22freeDDBhack. But always using an usb stick :)

@Dietmar I'm using the XP Integral Edition installed from an USB stick with the default acpi6666. I simply replaced acpi.sys.

@Dietmar until now the only acpi2 that works better is the "acpiFreeRyzenDDB" (SHA-1: 6F15AFDA2C31BC169996D4DAA4041CBF48C72EE6). But even with it sometimes the XP boot hangs on a blank screen and sometimes it hangs on the XP logo screen with the scroll bar. I can't be more precise because it happens randomly.

Just tried the "acpiV22freeDDBhack" on my GA-H470. I got the A5 BSOD (0x03, 0xA6672420, 0xC0140008, 0x494E495F). Also tested the "acpiV22free": A5 BSOD (0x011, 0x08, 0xB99AD000, 0x20160517)

@Mov AX, 0xDEAD There's no problem. I'm in no hurry

@Mov AX, 0xDEAD Intel

No problem for the first two points. For the third one I will organize. Trying is the least I can do. Let me know how to proceed.

@Dietmar thanks for the hacked acpi.sys. It worked as expected.

Hi guys @Dietmar many thanks for your last acpi.sys that solved the A5 bsod (0x03, ***, 0xC0140008, 0x494E495F) on almost all of my boards. Unfortunately, the A5 bsod is still there for the GA-H470-HD3 although it is now a bit different than before with the first acpi v2.0 release. Now: 0x11, 0x08, 0xB99AD000, 0x20160527 Before: 0x11, 0x08, 0xB998B000, 0x20160527
