Damnation

you're welcome! happy to hear you got it working!

maybe not all the USB drivers were copied across? I think this is a bug windows 2000 had. On your windows 2000 CD - go to \I386 and open DRIVER.CAB with 7zip or WinRAR, scroll down and extract everything with usb in the name and put it in \system32\drivers. See if that works. edit: these too - mouclass.sys mouhid.sys kdbclass.sys kbdhid.sys

I see that you have a native USB 2.0 controller on board Intel(R) 8 Series/C220 Series USB EHCI #2 - 8C2D PCI\VEN_8086&DEV_8C2D&SUBSYS_06121028&REV_04 PCI\VEN_8086&DEV_8C2D&SUBSYS_06121028 PCI\VEN_8086&DEV_8C2D&CC_0C0320 PCI\VEN_8086&DEV_8C2D&CC_0C03 ^ This should work for your mouse and keyboard since Windows 2000 has native USB 2.0 drivers.

Is there some other way to get in contact? I'd rather not join twitter.

Whats the best way to get in touch with Blackwingcat? I'd like to look at their extended core source code (assuming they'll let me) edit: whats the deviceID on that ? USB controller?

Try the mouse and keyboard out in the USB ports that you connected the Wireless N/Flashdisk to, does Keyboard/mouse work in those ports?

It's odd that the flash disk and Wireless N controller are working though, what motherboard do you have?

@winnt5 I thought OpenNT got taken down, did they pop up somewhere else?

@Win95rtm If I can get my ntoskrnl extender working, it should be possible to install an unmodified 368.91 driver on windows 2000.

The XP ACPI driver has been patched already and is working on AMD Ryzen desktop and Ryzen Threadripper. To get it to work for Windows 2000 I'll first need to resolve some missing imports in ntoskrnl InterlockedPopEntrySList InterlockedPushEntrySList ExfInterlockedCompareExchange64 HeadlessDispatch _aulldvrm Wish me luck.

@WinWord2000 OK, done. - It's still in the quote though, can you delete that?

@WinWord2000 Neither. I'll fork from this - link deleted - since I know it works. get it compiling for Win2kDDK and go from there.

@windows2 OK, will do, thanks. @Ximonite Have you heard of the ntoskrnl extender for XP? I can confirm that it works, I used it to install XP on my AMD Ryzen system, it works well, very stable. Interested in doing the same for 2000?

I'm thinking of working on a version of ntoskrnl extender for windows 2000 since it worked out so well giving us extended ACPI/AHCI/NVMe/USB3 support for XP. But now I'm wondering, is there that much interest in seeing it done?

@Dietmar If you're still active on this forum - do you remember if there was a way to safely switch from "ACPI Uniprocessor PC" to "ACPI multiproccessor PC" ?

@Dave-H It's odd that you got a 7B BSOD with option 1 - that's usually the driver that works. It works for my Threadripper 3960x machine, so it's odd that it does not work for you. Fortunately the integrator has alternative options for this reason. This time try options H, 3,4,5

@Dave-H Use the optional patch integrator on the integral edition (vanilla) ISO - that's what its for. option 4 will solve the A5 BSOD You'll also want options 1,3 and 5 So options 1,3,4,5 edit: integral edition found here https://www.zone94.com/downloads/software/operating-systems/123-windows-xp-professional-sp3-x86-integral-edition

@Dave-H In your registry, do a search for CC_0106 does it find anything?

@Dave-H First Check in device manager under "Computer" - If it says something other than "ACPI Multiprocessor PC" then ACPI isn't properly enabled.

@Dave-H Yes it will work - did you copy ntoskrn8.sys across to system32\drivers too? that is needed for it to work. ntoskrn8.sys is in \Integrator Files\Patches\Miscellaneous

@Dave-H It seems you're going to have to do the AHCI driver installation the slow way without the INF file. So you'll need to copy the modded storahci.sys and ntoskrn8.sys drivers into system32\drivers and then add in the registry keys one at a time by hand.

@Dave-H Included with the Integral edition Optional Patch Integrator is a backported version of the Windows 8.0 storahci driver for XP. To install it - go to \Integrator Files\Patches\Miscellaneous\ and copy ntoskrn8.sys into \system32\drivers\ of your XP install - this is needed for the backported driver to work. then go to \Integrator Files\Patches\MovAX-Gen2 SATA driver v2.0\ and install that backported storahci driver located in there.

@Dave-H I'm very interested in helping you solve this. So you want to get ACPI enabled on your system but without doing a fresh install is that right? TBH the easiest solution is to do a fresh install with XP integral edition using the Optional patch integrator which can be found here - https://www.zone94.com/downloads/software/operating-systems/123-windows-xp-professional-sp3-x86-integral-edition Applying the patches to an existing install is the more difficult route. Is preserving the existing installation a must? a new install is much easier thats why all the existing guides prefer it.

Has anyone taken a look at the uploaded source code? also, the source code for the AHCILDR.COM program and AHCI.PDR driver is still missing

I'd just use my B350 K4 motherboard and 2700x CPU instead.
