Damnation

@Mov AX, 0xDEAD I compared my 5950X system with my threadripper, On threadripper the CPUs are installed but not on my 5950X. I'm quite sure that this is the issue, but I'm not sure how to get the CPUs installed in Device manager. Any idea how to install them?

@GD 2W10 I am quite that a Surface Pro 1 will be UEFI only. There is experimental UEFI support for XP x64, but it's nowhere near stable.

@WinWord2000 If you can get me a copy of the driver I can check if the .sys file has it's dependencies met by the ntoskrnl extender. If dependencies are met That'll give you basic sound output at least. The bundled software still won't work though.

@WinWord2000 I think there should be some USB Sound Cards that will work with XP.

@R1600 I do have HWMonitor installed on XP, that's where I got the 140W from in the screenshot. Nothing about current CPU power state though.

@GD 2W10 no more HP Elitebook 840 G3?

@Mov AX, 0xDEAD I noticed that there are no processors listed in device manager, could that be the issue? In Win11 the HWID for the processor is ACPI\VEN_ACPI&DEV_0007 and no such device exists in XP.

@Mov AX, 0xDEAD Changing power Options did not help. ThrottleStop does not work on XP anymore. any other software you can think of? P.S I think this high power usage could be ACPI related, what do you think?

@Dietmar @Mov AX, 0xDEAD any other ideas to get CPU power under control?

@Dietmar Thanks. Unfortunately CPU Wattage is still high at 140W idle @Mov AX, 0xDEAD any ideas?

@Dietmar Can you upload the modded intelppm.sys for me to test?

@Dietmar Can you run a check with HWMonitor on your XP builds and see if any of them also have unusually high CPU wattage?

@Dietmar So LAN drivers designed to run on XP are not forward compatible to run on Win7?

@Mov AX, 0xDEAD I've noticed that my 5950X CPU is idleing at +60°C and consuming about 140W+ also when idle (at least according to HWMonitor) when booted into XP. I'm assuming this is ACPI related? could we debug this? It would be preferable for it to not consume so much power when idle.

@Die0x00000 You can use the Optional Patch integrator script included with XP Integral Edition to get all of that ACPI/AHCI/USB3/NVMe stuff sorted for you in a fully patched XP ISO. link: http://www.zone94.com/

I ended up taking the easy way out and got a different USB 3.0 hub that worked with no BSOD this one worked without BSOD - https://www.mwave.com.au/product/orico-at2u310ab-aluminium-10port-usb-30-hub-with-individual-switches-ac37890 this one gave the BSOD - https://www.ple.com.au/Products/626733/ALOGIC-Plus-10-Port-USB-30-Powered-Hub-With-Charging edit: I still have the problematic hub in my possession so if you want me to go ahead and debug with it anyway, just say so.

@amirsig Video Unavailable.

@daniel_k ah, OK.

@daniel_k I've noticed a similar issue on my Threadripper system with x86 XP - I think it has to do with more than 32 CPUs. maybe. Can I have your XP x64 ISO to test?

@Dietmar If you are able to do so, can you purchase a powered 10-port USB 3.0 hub like this one - https://www.ple.com.au/Products/626733/ALOGIC-Plus-10-Port-USB-30-Powered-Hub-With-Charging and test if you get BSODs in XP with it?

I've discovered a workaround, I can boot into XP if I connect the hub to one of the 2 USB 2.0 ports next to the 2.5gbe ethernet port. not the most ideal solution, but it's something. I'd still prefer to find the cause of this BSOD though. @Mov AX, 0xDEAD So I'm assuming I don't need to hex edit kd_02_10ec.dll at all? - just rename to kdnet10.dll? and I get kdstub.dll off of your github?

@Mov AX, 0xDEAD OK, so I copy and rename kd_02_10ec.dll to kdstub.dll/kdnet10.dll from windows 10 32bit over to my XP install. Do I need to do any other hex edits to these files for them to work correctly? or they should just work?

Hi @Mov AX, 0xDEAD On my new AMD B550 build I've come across a scenario where if I have a Powered USB 3.0 hub connected at boot, it causes a 0x50 dump_ntoskrn8.sys BSOD before reaching the desktop. Would you be willing to help me debug this? If so, can I have the realtek version of your KDNET to help with debugging this?

@Mov AX, 0xDEAD is there anyway we could motivate you to help us with getting this working?

@Mov AX, 0xDEAD Have you made any progress with getting NDIS6 working on your end? I'm more than willing to help if you want.
