Damnation

@Dietmar Do you only have access to 1 CPU core there? also, did Mov come up with a solution in acpi.sys source code for this?

@SEDANEH You're welcome! we're always willing to help!

@SEDANEH Just focus on getting the essential devices working, namely GPU, sound and networking for now.

@SEDANEH That's odd, I've never seen XP give a 7B error AFTER booting. Are you sure it was a 7B BSOD?

@SEDANEH Glad that you finally got XP installed! Integrated GPU won't have a proper XP driver, get an nvidia GT 710 that has XP drivers.

@OldSchool38 Have you got a pic of the BSOD? There are community made drivers for XP out there for newer hardware, it should be possible to get it working.

@SEDANEH I made a prepatched XP ISO for you. https://easyupload.io/2d87ov

@TheLeftOldComputer Have you heard of XP Integral Edition? It has an optional patch integrator script included with it that has community made patches that will resolve both your AHCI and ACPI issues.

@SEDANEH The pic looks like you're installing on a HP laptop now? Weren't you trying to install on an ASUS Z790 motherboard?

@Dietmar That's what I'm saying - add this code in to your HP DSDT table and then try and boot with it. leave out the lenovo tables. https://msfn.org/board/topic/183464-compiling-acpi-v20-driver-for-windows-xp-sp3-and-windows-2003-sp2-x32x64/?do=findComment&comment=1259789

@Dietmar Not the lenovo DSDT table. I meant just adding the missing ADR code for PRT4 into the HP laptops own DSDT table and see if it helps, that might resolve the 0xA5 0x0D BSOD you've been having.

That's what the optional patch integrator script is for. or you can use dietmar's prepatched ISO.

@Dietmar If you can load different ACPI table now, maybe try the DSDT modification you thought of earlier and see if it works? https://msfn.org/board/topic/183464-compiling-acpi-v20-driver-for-windows-xp-sp3-and-windows-2003-sp2-x32x64/?do=findComment&comment=1259789

@Dietmar Oh nice! thats good news!

@Dietmar Try the acpi table patcher included with agfm bundled with Easy2boot? I recall that it worked for me when I made a temporary table fix for ACPI0007 and CPU power.

@Dietmar If we can get this working it might help with that HP laptop thats been giving you trouble. Have you got a spare PC that you can use to debug this?

@SEDANEH No, the lack of an IDE connector doesn't matter. You'll need to learn to use the methods we showed you, or you can use the ISO that dietmar made for you. We're willing to help you, just ask.

@Dietmar I've made a my own custom HAL adding in ACPI table finding code into HalAcpiDispatchTable inside the HAL - I'm wondering if this might get us any closer to being able to boot XP with Vista RTM acpi.sys https://easyupload.io/ijwohe Still get a 7E BSOD with this but I'm wondering if it happens because of PmHalDispatchTable in acpi.sys or not, try it out when you have time.

@Dietmar Looking at the logs, is it shutting down because it thinks the CPU is too hot? I'm probably misreading that though.

@Dietmar I use acpidump.exe -b to dump acpi tables.

@Dietmar I think you made a mistake? Both DSDT tables are identical.

@Mov AX, 0xDEAD Is there a reason length was set at 0x1A? wouldn't 0x20 (max 32) make more sense?

@Dietmar In the meantime you can use upload site like https://easyupload.io/

@Dietmar Now I get a D1 BSOD from ntoskrn8.sys itself. https://ibb.co/gM52pG2 most recent build. https://easyupload.io/pklgtx I'll stop for now.

@Dietmar I thought I'd try and take another shot at porting NDIS 6 to XP. I got a D1 BSOD in netio.sys this time. https://ibb.co/q5VjMMh My most recent build if you want to try and debug, no rush. https://fastupload.io/pOM4uar97jSEMZn/file edit: looking at your last debug log from when you got a D1 BSOD i netio.sys I looked at the point of failure in a disassembler and from what I can tell I think it has to do with the hashtable functions that I stubbed, might try to implement.
