reboot12

@Dietmar Yeeeeeeeeaaaaaaaaaa - it works After disabling and enabling Microsoft UAA Bus Driver for High Definition Audio, WinXP finds 2 new sound devices - Realtek and Intel. I have drivers for Realtek so I can install them now and the sound works Thanks a lot Dietmar, I would never think of disabling then enabling UAA can help detect audio devices I need to add a script to the autostart which restarts the MS UAA driver and should be ok.

Can you read with understanding? I do not have a dedicated card, both are integrated - one of the Realtek motherboard and the other with the Intel processor and both work OK in Win7, Win10. The point is that in WinXP they are not visible in the device manager so I can't install the drivers. And no, in the bios it is impossible to disable the Intel card integrated with the processor, you can only disable the Realtek card integrated with the motherboard but I do not want to disable because I have drivers to it and I would like to use it in WinXP:

@Dietmar What double ??? I don't use CSMWrap because the motherboard has native CSM These are two completely different sound cards - one is a Realtek 10EC 0887 integrated with the motherboard and the other Intel integrated with the CPU 8086 2882

BIOS UEFI 64-bit but CSM available. Hi. I installed WinXP (Legacy) but in the Device Manager I can't see any (?) Unknown device or (?) Multimedia device for sound card (Realtek or Intel). On Win7 and Win10 there is no problem with that and both sound cards available:

Unfortunately, after a few days of testing, there is still a problem with the lag on Haswell machine. I changed OS to my favorite - WinXP 64-bit - everything works ok and I have full access to RAM P.S. I wanted to add a RAM patch to my project on MDL - WinXP 32-bit on a modern PC (ISO boot.wim + install.wim) but since it works unstable, I will probably give up Maybe I will add as an alternative in the boot.ini and BCD file but not as default.

@Dietmar Please extract bios from this: https://dl.dell.com/FOLDER13218127M/1/Wyse_5070_1.37.0.exe

@Karla Sleutel Supermium 126.0.6478.254 64-bit, XP64-bit - works in PL

@Dietmar A CSMWrap version has been released, which allows you to use the BIOS video from the disk from EFI\Boot\vgabios.bin https://github.com/FlyGoat/CSMWrap/issues/37#issuecomment-3030297746 Compiled bins: https://github.com/FlyGoat/CSMWrap/actions/runs/16040013218 Thanks to this, WinXP boot OK on iGPU using ntldr as on a normal Legacy machine - I tested CoffeeLake, Haswell, SandyBridge: CSM Disabled, iGPU VBIOS extracted from motherboard bios. Now - I don't have to use SeaVGABIOS and Longhorn bootmgr 5472 loader.

WinXPPAE 3.5 can't patch any SP2 hal version: Patching halmacpi.dll (ACPI Multiprocessor PC HAL)... Invalid file!

I don't know, but if you compare patched kernel files 5.1.2600.6368 in a hex editor and are changed exactly the same bytes in the same offsets, it means that they work the same. You must first patch using a patcher v3.5 kernel file 5.1.2600.6368 ntkrnlpa.exe 5.1.2600.6368 > https://catalog.update.microsoft.com/Search.aspx?q=2813170 WinXPPAE.bat script default patch all RAM: WinXPPAE.exe /M:ALL /NOBACKUP so, put ntkrnlpa.exe (GDR version) and WinXPPAE.exe in same folder then patch as above: winxppae /M:ALL Windows XP PAE Patcher 3.0 by daniel_k | HAL patches by <Mov AX, 0xDEAD> PAE will be enabled using all available RAM. Patching ntkrnlpa.exe (Uniprocessor PAE Kernel)... OK! File ntkrpamp.exe (Multiprocessor PAE Kernel) was not found. File hal.dll (Standard PC/Standard PC w/ C-Step i486 HAL) was not found. File halaacpi.dll (ACPI Uniprocessor PC HAL) was not found. File halacpi.dll (ACPI PC HAL) was not found. File halapic.dll (MPS Uniprocessor PC HAL) was not found. File halmacpi.dll (ACPI Multiprocessor PC HAL) was not found. File halmps.dll (MPS Multiprocessor PC HAL) was not found. No, this is not simple to compare - too big differences :-( Probably ntkl64g.exe is compiled from source code. org vs v35 differ only in 11 bytes: Search for differences 1. org_ntkrnlpa.exe: 2 070 016 bytes 2. 35_ntkrnlpa.exe: 2 070 016 bytes Offsets: hexadec. 138: C2 04 139: FF 03 13A: 1F 20 16B632: 07 00 16B637: 01 02 1703C2: 74 EB 1BE554: 10 00 1BE555: 00 02 1BE56A: 1B 00 1BE572: FC F8 1BE576: 01 02 11 difference(s) found.

This is not impressive - simply this is patched ntkrpamp.exe for multi CPU/multi core use: Modern computers have multi-core processors and the use of RAM patch on old PC does not make sense because old computers with a single-core processor do not support a large amount of RAM and a patch is not needed. Therefore, the 64G patch does not contain other kernal and hal files.

@Ascii2 I make big tests: using Macrium Reflect clone OS to other HDD - still problem replace RAM modules - still problem use only 2GB RAM 1+1 - still problem using Macrium Reflect make disk image, then restore on other PC - Haswell 8GB RAM (4+4 Dual Channel), OS boot, find new devices, I install drivers. I test and it looks like there is no problem and WinXPPAE 3.5 works well :-) I use exactly same patched files and settings: ntkrnl2.exe SP2 5.1.2600.2180 + hal2.dll SP3 5.1.2600.5512, noexecute=optin I have to use the system for some time to make sure 100% that there is no problem. It seems that the problem is only on SandyBridge machines.

No. /PAE switch load Ntkrnlpa.exe I use only like this and PAE works: /noexecute=optin /fastdetect /kernel=ntkrnl2.exe /hal=hal2.dll Enabling PAE Windows automatically enables PAE if DEP is enabled on a computer that supports hardware-enabled DEP The PAE kernel can be enabled automatically without the /PAE switch present in the boot entry if the system has DEP enabled (/NOEXECUTE switch is present) or the system processor supports hardware-enforced DEP. Presence of the /NOEXECUTE switch on a system with a processor that supports hardware-enforced DEP implies the /PAE switch. If the system processor is capable of hardware-enforced DEP and the /NOEXECUTE switch is not present in the boot entry, Windows assumes /NOEXECUTE=optin by default and enables PAE mode. You need use /NOPAE because default (optin) is enabled: https://web.archive.org/web/20060313135704/http://support.microsoft.com/kb/900524/

Yea, I use SP2: ntkrnl2.exe SP2 5.1.2600.2180 (patched by WinXPPAE 3.5 on SP2 OS) + hal2.dll SP3 5.1.2600.5512 (patched by WinXPPAE 3.5 on SP3 OS because the patcher cannot patches the hal.dll SP2 version) ntkrnl3.exe SP3 5.1.2600.5512 + hal3.dll SP3 5.1.2600.5512 - both patched by WinXPPAE 3.5 on SP3 OS ntkl64g.exe SP3 5.1.2600.6368 + hal64g.dll SP3 5.1.2600.5512 - files from @Dave-H 64 GB of RAM patch.zip I test (for a short time) my XP SP2 on other machines and probably no lag issue but this is fresh installed OS - no any drivers, apps. maybe lag issue is only on my SandyBridge machine recently I changed 2x4GB RAM - maybe they cause the problem? my OS has all drivers and many applications installed - maybe some application or driver works badly with a RAM patcher? I have to test the patch for a long time on other computers + all drivers installed. boot.ini [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="RAM v3.5" /noexecute=optin /fastdetect /kernel=ntkrnl2.exe /hal=hal2.dll multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="WinXP" /noexecute=optin /fastdetect This is my table when DEP/PAE works on WinXP SP2 depending on the setting of the noexecute option in boot.ini So, I do not have to use boot.ini switch /PAE because noexecute=optin is enough.

@Dietmar @Mov AX, 0xDEAD I use the WinXPPAE 3.5 patch for a week and I noticed a problem with disk operations - the same is for the 64G version: Video when ram patch is used - lags: https://files.catbox.moe/ericzb.zip Video when no ram patch: https://www.sendspace.com/file/17e170 Testing config: Asus P8H61-M LE R2.0 RAM 2x4GB DDR3-1600 Dual-Channel CPU Intel Core i3-2120 WinXP SP2 Pro HDD: SATA in AHCI mode

@Dietmar I spent a bigger half day today testing XP32 with iGPU and I have good news. XP runs best with iGPU (Haswell) on vbemp.sys (PNP) 2015 driver in co-op with my UefiSeven (u7nwbm.efi + UefiSeven.ini with set native resolution of monitor) and Longhorn 5472 bootmgr+BCD+winload.exe loader - iGPU need be set as Primary Display in bios XP can be run in the native resolution of the monitor - it depends on the monitor connected and the cable used (probably also on the EDID), the aurora boot screen is badly displayed when the resolution is native but the XP desktop works fine you can change the available resolutions - if the resolution is lower than the native one, the desktop is displayed from the top right corner without cleaning the screen - the previous content remains on the screen original XP vga.sys driver works badly with UefiSeven, there are some resolutions to choose from display settings but trying to change it restarts XP I boot XP in this way: in bios CSM Disabled (pure UEFI) > PC boot UEFI Shell from FAT32 100MB from EFI\Boot\bootx64.efi > startup.nsh starts UefiSeven and CSMWrap 1.2.1 (in UefiSeven.ini file native resolution monitor is set) NOTE: During installation of the vbemp driver, the system reboots but after the reboot it already starts on the vbemp driver at 640x480 and you can change the resolution to another e.g. native (if UefiSeven was previously running at this resolution) My monitor native resolution is 1360x768 but I test also other monitors native 1920x1080 and native 2560x1440 - see screenshots at bottom.

I compile CSMWrap replacing SeaVGABIOS to ValleyView Legacy video BIOS extracted from Jetway HPC070SC industrial computer: https://github.com/FlyGoat/CSMWrap/issues/37#issuecomment-2921265627 Risky to use on other Laptops but this is Mobile/Desktop version so should work on desktop computers: https://files.catbox.moe/6xj4hm.zip User win98se on github test this version, "But the graphics are glitched, and after spinning for a while" but not damaged: https://github.com/FlyGoat/CSMWrap/issues/39#issuecomment-2977152878

No, they probably already corrected the repository and now git clones the latest version :-)

OK, git corrected and now downloads the current version This is full tutorial how compile CSMWrap: Download and install Ubuntu: https://releases.ubuntu.com/noble/ubuntu-24.04.2-live-server-amd64.iso During installation, select Install OpenSSH server - this makes it easy to copy files from Ubuntu to Windows using WinSCP and use Ubuntu over SSH e.g. in Putty sudo passwd root (enter password for user) sudo passwd root (make new password for root) sudo login root or reboot and login using root nano /etc/ssh/sshd_config PermitRootLogin yes PasswordAuthentication yes Ctrl+o to save and Ctrl+x to exit service ssh restart apt update apt install -y build-essential nasm curl xxd net-tools git clone https://github.com/FlyGoat/CSMWrap.git --recursive cd CSMWrap make seabios make ifconfig - to check IP using WinSCP make connection and connect to Ubuntu: New Site, File protocol: SCP, Host name: IP, root User name and Password, Save

@Dietmar No, I tried like this but errors: wget https://github.com/FlyGoat/CSMWrap/archive/refs/tags/1.2.1.tar.gz tar -xvf 1.2.1.tar.gz mv CSMWrap-1.2.1 csmwrap cd csmwrap root@ubuntu:~/csmwrap# make seabios make -C seabios distclean make[1]: Entering directory '/root/csmwrap/seabios' make[1]: *** No rule to make target 'distclean'.

Stop. F..k, but a mess

OK, but this compile version 1.1.0-12

OK, finally works I was running all the time with CSMWrap and it turned out that with this it doesn't work on Haswell: https://forums.mydigitallife.net/threads/winxppae-v3-5-winxp-sp2-issue.89363/#post-1881947 Also, the ntkl64g.exe file has a bad checksum and doesn't work when trying to run using winload.exe - error 221: setcsum ntkl64g.exe SetCSUM v1.01, (c)2000 Jeremy Collake http://www.collakesoftware.com mailto:collake@charter.net ---------------------------------------------------------------------- .\ntkl64g.exe = Header Checksum: 001FACDE Correct Checksum: 001FF99B Checksums do not match!
