@George King Can you please compile a "free" version of acpi.sys ver2.0 ? Because with dirty hack, the acpi.sys "Debug" version shows always BSOD 0x7E (0x80000003,..) meaning that a Breakpoint is reached Dietmar

On the new z690 Asrock extreme board, the new Vers 2.0 acpi.sys gives BSOD 0x000000A5 (0x00000003, 0x98E1DBA4, 0xC0140008, 0x494E495F) so until now manual hack in acpi.sys with IDAPro is needed also Dietmar PS: _ValidateArgTypes was called with 2nd arg = pointer to string with "H" char inside at winxp_5512 exist C, I, O, A, B, D, .. but not "H"

@Mov AX, 0xDEAD @George King I just test the new acpi.sys on the Asrock z370 Fatalty k6 board with 32 Gbyte ram. It works, nicccceeeeeeee!!!!!!!!! Interesting, that the Acpi error about mistake in DDB 0x000000A5 (0x00000011, 0x00000008, xxx, yyy) is not longer shown without any mod Dietmar

@Dave-H Without a 3 times checked whole Bios copy via EEpromer I would not do anything with Bios on the Flex 10. I for myself had the situation also with the Flex 10, that after modding the Bios it looks like dead. And in this case the only possibility is reflash original Bios via EEpromer. For DSDT the situation is a little bit other. You can upload an DSDT on the fly even in XP without any mod in Bios. But I never succeed with this Dietmar

Hi Dave, in this case your only chance is to mod your DSDT. Can you send me your DSDT form your Flex 10, extracted from Bios via iasl.exe Dietmar

@Dave-H Hi, here is my modded Bios for 64 Bit for the Flex 10 with n2806 cpu. https://ufile.io/taqxqvhl It has a working DSDT table inside for full Acpi XP SP3 and the ahci harddisk. Also I deleted the Whitelist in this Bios, so you can install every device that you want. This is the full 8Mbyte Bios, I think it can be only installed with an EEpromer. Make sure, that you have the Flex 10 version with n2806 cpu. There exist another, 32 bit Flex 10 with n2805 cpu. This n2805 is NOT compatible with my Bios! Make sure, that you make (read out) three valid copies of your Original Bios and compare them, that they are identic. I use the very best EEpromer REVELPROG IS via Ebay, costs about 150 Euro. Have a nice day Dietmar PS: I desolder the Bios chip from the Lenovo Flex 10 board. But do this only, if you are good in soldering:)).

@Dave-H Crazy hard work, to get XP SP3 to work on the Flex 10 board. At the end I get everything to work, only not the graphik driver. After loong searching in the dark I noticed, that ALL the problems of this board belongs to its DSDT table in Bios. Intel did all for the Baytrail chipset, that XP and even Win7 and Win8 do not run on it. After I changed DSDT in Bios (also crazy procedure, because I can do this only with EEPROMER), the problems are gone Dietmar PS: Now I am in Ukraine until 8 of January. Only at home I have this ready modded Bios.

@FantasyAcquiesce Do you get the Radeon x1300 to work under Win98? I tried x1400 on a Thinkpad T60 without success Dietmar

Yesssssssssssssssssssssaaaaaaaaaaaaaaaaaaa all USB3 on XP SP3 on Intel chipset on full ACPI Multiprocessor https://www.win-raid.com/t4035f45-Windows-XP-SP-bit-and-modern-PC-parts-86.html#msg84052 Dietmar

Now USB 3.0 works also on Intel chipset under XP SP3 Yesssssssssssssssssssssssssssssssssssaaaaaaaaaaaaaaaaaaaaaaaa:))))))))))))))))))!!!!!!!!!!!! Dietmar https://www.win-raid.com/t4035f45-Windows-XP-SP-bit-and-modern-PC-parts-82.html#msg83830

I succeed with USB 3.1 for USB boot XP SP3, Kanguru USB stick works fantastic, even write protected Dietmar https://www.win-raid.com/t4035f45-Windows-XP-SP-bit-and-modern-PC-parts-19.html#msg68271

Yessssssssssssssssssssssssssssssaaaaaaaaaaaaaaaaaa, I got all USB 3.0 3.1 3.2 drivers to work under XP SP3 !!!!! https://www.win-raid.com/t4035f45-Windows-XP-SP-bit-and-modern-PC-parts-72.html#msg83048

@~♥Aiko♥Chan♥~ The problem for me is, how to test acpi.sys for XP SP3 there because I do not have this board. But because it is sold in the time when XP was still spported, there a good chances for success, Dietmar PS: May be it can be done easy with fixed DSDT table. What is the exact BSOD 0xA5 (...)? Make a copy of this DSDT table using RW everything (XP, win7, win8, win10) and send it to me. With the nice program asl.exe the DSDT table is modded one time and stays in registry. This can be done without any ACPI, from "Standard PC". I have tested, works for XP SP3 without any need for modified acpi.sys or hacking Bios.

XP SP3 runs in full ACPI mode with nearly all drivers on Ryzen 3700x https://www.win-raid.com/t4035f45-Windows-XP-SP-bit-and-modern-PC-parts-68.html#msg82490 Dietmar

makecab acpi.sys is enough, gives you acpi.sy_ Dietmar

Best is, to make a new *.iso install CD for XP SP3 with nlite. And in installationsfolder, just change acpi.sys against new version via makecab.exe Dietmar PS: I tested this on 2 AM4 boards, asrock fatal1ty ab350 gaming k4 and asus prime b350 plus and a lot of newer Intel boards, works everywhere.

New acpi.sys I make which works until now on any XP SP3. AMD, Intel, new, old boards, all languages. Please test test test and tell results Dietmar acpi.rar

XP works on Ryzen https://www.win-raid.com/t4035f45-Windows-XP-SP-bit-and-modern-PC-parts-51.html#msg80487 Dietmar

Vista 32 bit does not work on B350 chipset (Ryzen). Only the 64 bit legacy Vista version works. On the Asrock fatal1ty ab350 gaming k4 it is impossible to have any kind of Vista 32 bit, because there is no APIC mode in Bios, only PIC. And because of this you get BSOD "no Acpi compatible Bios", no matter if you install Vista or use it from another compi (I try Vista 32 bit from AM3+ board) Dietmar

Hi, I am happy, when all AMD Ryzen users can make a quick test via rw-everything, if there is a MPS table on their board. For this, just click MPS on top of the RW-everything window Dietmar PS: I do not succeed to install Vista 32 bit on any Ryzen board. It is, because APIC mode is not enabled via Bios, and so ACPI fails.

New acpi.sys for XP SP3 32 bit, all languages and compis. Please tell me results for making things better Dietmar acpi.rar EDIT: The problem is more complex: On my asrock fatal1ty z370 gaming k6 with acpi.sys 5048 I get again BSOD 0xA5 (0x03, xxx, C0140008, yyy). And in its Bios I isolated ALL CreateQwordField instructions. EDIT2: The problem may be really in QwordConstant: acpi.sys from XP has no problem with this word. But acpi.sys 5048 has. This I know, because in DSDT table from the asrock fatal1ty z370 gaming k6 there appear QwordMemory and QwordAcc. I do not isolate them. XP boots. And may be because of QwordMemory and QwordAcc BSOD 0xA5 (0x03, xxx, C0140008, yyy) with acpi.sys 5084 on the Asrock board. So, at the moment, acpi.sys 5084 is worse than my modded acpi.sys before.

I think, this one will work Intel X540-T2 (I prefer with only one RJ45 connector Intel X540-T1) Ethernet Adapter for 10 GBit, interesting, because I look for the same. Drivers in 18.3 packet from Intel for Win Server 2003 32 bit, so XP SP3 32 bit:)), Dietmar PS: Quick search via geizhals.de tells, that this are the only networkcards for 10 Gbit/s which work for XP 32 bit also.

Today I make an update of the acpi.sys driver for Windows XP SP3 32 bit which should work on any compi. AMD, Intel, language does not matter Dietmar acpi.rar

At https://www.win-raid.com/t4035f45-Windows-XP-SP-bit-and-modern-PC-parts.html you can see the whole thread. I tried to build a complete new acpi.sys for XP because I know, that the very first version of Vista Longhorn April 2005 had the same problem with ACPI, because based on ACPI 1.b. Later versions of Vista learns new vocabulary, 14 pieces from ACPI 2.0. This I tried to teach them XP acpi.sys also. But it needs so much time and I can do this kind of fun only in my holidays. Read the thread at Fernando. The latest Bios for the APEX X motherboard does not need any more than those 3 files, no need to change Bios! But other manufactures BIOS are worse. By the way, the clock changed in newer chipsets. Until now, I do not see a XP Bios, with working clock z370, z390 and ACPI. So, you need also hal.dll for clock and intelppm.sys for powermanagment C1, C2..states Dietmar
