Hi, everyone! I'm trying to install Windows Vista on Acer Travelmate P215-52G laptop (from 2020 era). It has Comet Lake chipset, i5-10210U CPU, Intel UHD Graphics iGPU, Nvidia MX230 GPU and 2x8 GB DDR4 RAM. I tried modded ACPI.SYS files for Windows XP and 7 but none of them worked. WinXP ones gave 0x000000A5 ACPI BSOD. Win7 ones gave 0xc00000098 boot error. Also tried HEX editing 84 C0 75 1F to 84 C0 90 90 and 85 C0 78 2E to 85 C0 90 90 but gave 0x000000A5 ACPI BSOD. Can anyone help me or have correct modded acpi.sys for vista x64? Thanks from now!

DiskGenius v5.6.1.1580 1) The Free = Lite version is portable, works under WinXP and can be downloaded from https://web.archive.org/web/20250604191504/https://download.eassos.com/DGLiteEng5611580_x86.zip [8,619,143 bytes] 2) The unregistered, full portable version which works under WinXP can be downloaded from: https://web.archive.org/web/20250306141906/https://download.diskgenius.com/DGEng5611580_x86.zip [34,571,542 bytes] -> Help -> Register displays "Thank you for upgrading the software" To register, Options.ini, containing the registration code, has to be copied into the folder of the unregistered portable version. 3) There is also a repack of full v5.6.1.1580 which installs and works OK under WinXP. The .exe contains the full installer and full portable for 32bit and 64bit [61,461,381 bytes] The main difference between the full portable and full installer versions is the \dos\ subfolder, contained only in the full installer version. \dos\ contains DiskGenius v5.2.0.878 for DOS (8Oct2019), a specced-down build. 4) I have created a 1680kB boot floppy containing DiskGenius v5.2.0.878 for DOS. On a FreeDOS 1.4 (2Apr2025) boot floppy https://freedos.org/download/ containing only COMMAND.COM and KERNEL.SYS, I edited CONFIG.SYS and autoexec.bat, and then added from \dos\: diskgen.exe, CTMOUSE.EXE, himem.exe and fdapm.com (not sure whether fdapm.com is needed). Altogether 71,680 bytes are still free on the 1680kB floppy, e.g. for partition table backups (12+2kB each). If the repacked installer of v5.6.1.1580 cannot be found, there is an alternative for finding the \dos\ folder: The \dos\ folder in the repacked installer of v5.6.1 is identical to \dos\ contained in DGEngSetup520884.exe [DiskGenius v5.2.0.884 (installer, 8Oct2019)]. DGEngSetup520884.exe can be downloaded from https://web.archive.org/web/20200110041301/http://engdownload.eassos.cn/DGEngSetup520884.exe The \dos\ folder can then be extracted with UniExtract [v1.6.1.2035 (koros mod, 13Dec2018)] from DGEngSetup520884.exe. Alternatively, the \dos\ folder can be obtained by installing DGEngSetup520884.exe under WinXP, e.g. into a sandbox for not adding stuff to the registry etc This DiskGenius boot floppy still needs a lot of testing, Some uses could be to create and restore partition tables on very old computers, or to access GPT HDDs >2TB under DOS. The photo below shows that DiskGenius can correctly access under DOS a 4TB GPT HDD.The 4TB HDD is nearly full (light brown=free space).The file 22dsk144.zip is displayed by DiskGenius in the final 1200GB partition, i.e. past 2.2TB. The 4TB HDD was in an external eSATA docking station, connected as secondary master to the motherboard. The last version of installed/portable DiskGenius [formerly named PartitionGuru] for WinXP on very old computers with an SSE-only CPU (Pentium 3) is PartitionGuru v4.7.0.105 (7Feb2015). The DiskGenius v5.2.0 DOS boot floppy, however, does work with SSE-only computers. Unfortunately, diskgen.exe does not run under Win98, there seems to be an issue with CTMOUSE.EXE

I will check my registry entries when I am back at my desktop computer. Thanks for the heads up!

TBH, I don't think that any website operator is still interested in compatibility problems of an unsupported and rather unknown browser like Serpent on an operating system like Windows XP that has not been supported for a long time. So don't expect an answer or support!

Thanks for replying! The last official Chrome which supported Windows XP was the version 49.0.2623.112. I think I have a copy of it in my archive. In any case, I will check if the hardware acceleration worked at all in this version on my hardware and report here.

TBH, all this benchmark stuff doesn't help me at all. I play a certain YouTube video on the browsers and know immediately whether hardware acceleration is being used or not. The problem with Thorium, however, is that part of the hardware acceleration (GPU rasterisation) is not running properly on my hardware. Your benchmark images don't help me at all. And comparing different browsers with each other makes no sense either. You have probably not configured Mypal 68 correctly via about:config. Switching on hardware acceleration in the options page of Mypal 68 is not enough, at least in my installation.

I tested the most recent Chrome XP API Adapter on my system with Pentium 4 single-core and NVIDIA 6200. Generally, this adapter is great as it offers the possibility to enable hardware acceleration. Although the hardware acceleration can be switched on, there are negative side-effects. All popups now have a black background, which then appears as a black frame. Apart from that, the GPU rasterisation does not really work and leads to permanent delays. Furthermore, some of my toolbar icons that belong to extensions disappear. Thus, I had to switch off GPU rasterisation. Contrary to these problems in Thorium, the hardware acceleration in Mypal 68 and New Moon 28 works great without any problems. That means hardware acceleration is generally possible on my system and can be used if this feature is supported by a browser, especially with hardware as old as mine.

Unfortunately, no. It doesn't work properly on my system.

Thank you for the attention, sorry, I'll not go offtopic. I'm a new member, I obvioulsy don't know how everything works here, but I find it odd why would you want me to, at the same time implying @UCyborg's posts are off-topic. I will post my findings with XP. when I'm finished with them, don't worry. Again, thank you for the attention! I read through this thread and became a huge fan of@AstroSkipper , for his hard work and findings. I saw numerous times you zealously suggest a very dangerous software named "Kaspersky". I fail to get why. Why would you want to harm the others? Isn't it against the rules to advise harmful soft, when it's publicly known, declared by the US officials, and explained to you personally multiple times. And again, posting about Kaspersky is also indeed offtopic, since it's been removed by the OP, due to the discovered infection risks and harm it brings. https://nvd.nist.gov/vuln/detail/CVE-2019-8286

@AstroSkipper, thank you for the professional, more than well-written reviews in outstanding English, it helps us save so much time! What would we do without you! Now I'll not waste my time with that dodgy FW.

32-bit Vista could be a temp replacement, since it doesn't.

United Kingdom, one of my favourites! I learnt British English at school. I'm sorry I misspelt the Komodo name, I didn't even think it would be that humorous! I'll test older versions then, report back! Muchly appreciated! Ta muchly!
