Thanks @jaclaz! I tried what you said, but used the file linked to by @RainyShadowearlier as I think that's the one that also had drivers for USB 3.0 so may be more up to date. In that file, the path is Packages\Drivers\SBDrv\hseries\AHCI_svr\XP\ It seems to contain the same set of files. Trying to update the controller from there just produced "couldn't find a better driver than the one already installed". Looking in the RAID folder instead, the ahcix86.inf file does not contain a reference to my hardware ID, which is PCI\VEN_1022&DEV_7800. Should I try just adding it?

I tried running the MSI file in the ACHI driver package, and it just said it wasn't designed for my OS. I suppose I could hack the MSI file with Orca, but I very much doubt if it would do any good. I did find a package for AMD-based Lenovo machines called "IN1VDO11WW1.exe". This supposedly contains XP drivers for all the AMD devices. It won't install the graphics driver sadly, but it did install several others. My SATA controller driver is now "AMD SATA Controller (IDE Mode)". This sort of implies that there is an ACHI mode as well, but how do you switch it? Just selecting AHCI on the BIOS certainly doesn't work, it just BSODs again. I then tried the driver you found, and that updated some more devices, including USB 3.0, which is good. It still didn't install a graphics driver though. The devices I am still now missing drivers for are the graphics, Ethernet controller, and one "Unknown device". How do you uninstall the VBEMP driver? I can't see anything on the documentation pages about how to get rid of it! If I remove the device, it just puts the non-functioning driver back again, and there's the added annoyance that I have to OK its use on every boot! There's certainly no option in Add/Remove programs to uninstall it, and it doesn't appear in the HP System Diagnostics analysis either so I can't remove it there. I got two more SNP files from SDIO, this time when running XP. I don't know why it generated two of them, I suspect they are identical but I've attached them both just in case! Cheers, Dave. 2020_03_24__12_42_41__NETBOOK_state.snp 2020_03_24__12_42_44__NETBOOK_state.snp

Thanks again. That driver doesn't look very promising, but I will give it a try! It's a Catalyst driver, not a Radeon driver, but you never know! Backup now 75% done...........

The backup is about a third of the way through! I will try running SDIO on XP once it's finished, and attach the new analysis file.

Glad things are not too awful where you are @jaclaz. I'm now using Windows 8.1 to do an ISO backup of all three partitions on the machine, which will take a long time! I already had tried installing the AHCI driver using the Device Manager, but it just said that the INF file had no information about my hardware. I will try again with the MSI file. I also tried the VBEMP graphics driver, and it went through the motions of installing, and then said the device couldn't start (code 10). I used the 20 version as the documentation said that was best for flat screen displays. @RainyShadow did you say there was another possible graphics driver somewhere? Once the backup is done, I will have another go. I'm just so pleased to have finally got into Windows XP at all! Cheers, Dave.

Thank you, that worked! I also set the IntelIDE service to disabled for good measure, and removed everything from the registry "run" key that I was worried about. XP has now started, in IDE mode. It's complaining that it needs to be reactivated, but that's a minor issue! Now to try to configure it to run in AHCI mode. I guess just installing that AHCI driver that @RainyShadowattached earlier should do the trick? P.S. @jaclaz I hope things are OK for you and yours at the moment.

Oh dear, that doesn't sound good! I'm wondering if perhaps something is trying to run on boot with is crashing the system, I would imagine that the Intel Application Accelerator is still trying to run for instance, which is now incompatible. It doesn't BSOD instantly like it did with the 7B error, it does try to load, although the progress bar is stopping and starting, and eventually it produces the 7E BSOD. As I can access the XP registry in 8.1 using Registry Workshop, do you think it's worth trying to remove all the startup items there? @jaclaz or anyone else any ideas?

OK, I tried that. Windows 8.1 now blue screens on the OS selection menu, but if I select XP on the menu when in AHCI mode and then go into the BIOS after it reboots to XP and select IDE mode, it does work. I'm still getting a BSOD on Windows XP though, this time 0x7E instead of 0x7B. Incidentally, if I had run DriverInjection as an Administrator in the first place, do you think I would have had to still change the permissions on the system hive file? Do you think i should now put its permissions back to as they were before? I can obviously easily remove myself as a user on the file permissions, but how do I change the ownership back to what it was before? Before I changed it, it said "unable to display owner", and I'm not sure you can clear ownership once you've set it.

Oops, yes of course I meant AHCI! Just off out now, but I'll let you know how it goes later. Thanks, Dave.

No, it's still on ACPI. I can't run 8.1 with it in IDE mode.

Well the process apparently completed successfully, but I'm still getting an immediate 7B stop error when I try to run XP.

Ah-ha, thank you, I should have thought of that!

Hi again @RainyShadow! I'm now trying to use DriverInjection to put the AMD AHCI driver onto the XP system. Once I got my head around it, all went well until I came to load the system registry hive on the XP system. First I couldn't access it, so I took ownership of the "system" file and gave myself full control. Now it loads OK, but then just puts up an error message "Error 1x2: Error loading structure." Any ideas? Thanks, Dave.

Sorry, still configuring other bits of Windows 8.1, then I'm going to bed! I'm not sure about using floppy disks, there is no facility for that on this machine of course! Where do I get the SDIO video driver?

Thanks! Sorry, what do you mean by "F6 floppy image and the extracted files from inside." I already have a video driver from bearwindows which is apparently a generic driver which should work. Is the SDIO one different? Cheers, Dave.

Thanks again! The file from Snappy Driver Installer is attached. The X102BA and X102B are the same thing. There is a lot of confusion around that! 2020_03_21__22_05_49__X102BNETBOOK_state.snp

Thanks @RainyShadow! I don't fancy your first method too much as it's a small netbook, not a desktop, so physically moving things around isn't straightforward! I'll certainly try it if all else fails. I can boot into Windows 8.1 in AHCI mode with no problem, and I used to do that in XP too, using the Intel Application Accelerator. Doing the research, it looks as if XP supports AHCI with no problem, as long as it has the right driver installed. Unfortunately all the information I've found about configuring that driver depend on actually being able to boot into XP in the first place, which at the moment I can't do! I can access all the XP files in 8.1 of course, and I should be able to access the XP registry in 8.1, using Registry Workshop. If I did that and changed the entries in the XP registry to match your file, is it possible that it would work? I'm not at all sure whether XP has the right drivers installed, the Application Accelerator may have been overriding things. Is there any way of checking that in the XP file system? Thanks, Dave.

Hi Jaclaz! It's an Asus X102B touchscreen netbook, designed for Windows 8. It's based on an AMD A4-1200 APU with combined Radeon HD8180 graphics. It says it's using the standard MS SATA AHCI controller in Windows 8.1 Device Manager.

Well, I now have another problem! With my old netbook, I found that Windows XP would not boot with the SATA controller in AHCI mode, I had to use IDE mode. Windows 8.1 was fine of course. I fixed that by installing the Intel Application Accelerator, which enabled it to boot in AHCI mode. I anticipated the same problem with the replacement machine, and of course I found that as expected it wouldn't boot XP in AHCI mode, but changing the mode to IDE now makes no difference, it still won't start, with stop 7B (Inaccessible Boot Device). Also, Windows 8.1 won't boot in IDE mode either, also blue screening. So, I can only get into Windows 8.1 in AHCI mode, and I can't get into Windows XP at all! The other fly in the ointment is that the replacement machine is AMD based, not Intel based, so I obviously can't use the Intel Application Accelerator. Help!

Thanks very much indeed, that makes perfect sense! So I guess if I was only using Windows 8.1 I could switch off CSM and have secure boot, but with the dual boot setup that's not possible. As long as it can be made to work that's fine by me! Cheers, Dave.

OK, I've got it working, but I still don't really understand how! Playing with the BIOS settings, I tried enabling the "Launch CSM" option, which I had to disable the "Secure Boot" option to be able to do. It immediately came good, without me having to put any other boot settings in, the disk was recognised and the system booted from it! So, why did I have to do that, why does it boot from its original disk with "Launch CSM" disabled, but won't boot with the replacement disk? Is there any problem with using it in the mode it's now in, especially as "Secure Boot" can no longer be enabled (if i enable it "Launch CSM" is automatically disabled and it no longer works.) Any insight gratefully receiver, this is yet more completely new territory for me! Thanks, Dave.

Not sure whether this should be here or not, but it is sort of XP related. I recently acquired another second hand Asus netbook, and I'm hoping to replace my existing Asus netbook with it. I want to transfer the whole previous system across simply by moving the boot disk from the old netbook to the new one, but I've run into a problem (as always!) I've installed the disk into the replacement machine, but it won't boot from it, it only goes straight into the BIOS settings. The SSD is being correctly recognised by the BIOS, but all my attempts to add it as a new boot option have failed. When I select "path for boot option" it shows the disk correctly, but none of the *.efi files I can find actually work, when I add the new boot option, nothing happens. Now, here's the complications! The previous machine was dual boot, with Windows 8.1 and Windows XP. I used Easy BCD to configure that, to give me the necessary menu to select which OS I wanted to use. The other possible complication is that both operating systems are 32 bit, and the machine is 64 bit. I know that I can run a 32 bit OS on a 64 bit machine fine, but is the BIOS expecting 64 bit *.efi files? There are none on the disk of course. I've done a lot of research on this, but haven't fond anything that directly relates to this specific problem, most of it is very confusing to me! I have an ISO backup of all the partitions on the disk, it's partitioned into three drives, Windows 8.1 on C:, Windows XP on D:, and a smaller storage drive which is F:. Presumably I need to find the boot files from Easy BCD, but where are they? The BIOS is only offering the folders on the C: drive, I can't see any others, presumably this is because it's the active drive. There is a <Boot> folder in the root, which seems to just contain folders for different languages, but there's nothing usable there. There is also a <Boot> subfolder in the <Windows> folder, and that has an <EFI> subfolder which contains "bootmgr.efi" and "bootmgfw.efi". Neither of these files work to add a boot option though. Anyone any ideas? Surely this must be possible to do with out reformatting the drive and starting again! Thanks, Dave.

Thanks guys, I will give that a try and let you know how it goes! The Intel driver I have on my previous netbook was quite restricted, no acceleration for instance, and the UI was hardly very user friendly, but I could go to full HD resolution (with an HDMI connected external monitor) so I hope this will do the same. If not, as long as the built-in screen can get out of the basic VGA mode I will be happy.

I think I know what the answer is going to be, but I've just got hold of a second hand ASUS netbook which has an AMD Radeon HD8180 graphics system. I'd like to dual boot it with Windows XP and Windows 10, as my older netbook was booted with Windows XP and Windows 8.1, but I cannot find an XP graphics driver for it. The old netbook had Intel graphics, and there was a very basic Intel driver which worked with it on XP, but I can't find an AMD equivalent. While there are obviously no official XP AMD drivers for this hardware, has anyone running XP had any success with other older drivers, by INF editing etc.? I only want it to work at a very basic level, but not with the basic Microsoft driver if I can help it! Thanks, Dave.

Just one update for Word this month, KB4484240. Installed via Microsoft Update with no problems. The clock is ticking down to end of support in October, but let's hope future updates stay XP compatible until then!
