May 20, 2025, 9:44 PMFor those curious, the system is booted with the help of a USB stick containing @manawyrm 's NVMe BIOS OptionROM: https://github.com/Manawyrm/nvme-int13h-optionrom
And the installer ISO is patched to include a backported NVMe and USB3.0 driver through this package: https://zone94.com/software/operating-systems/123-windows-xp-professional-sp3-x86-integral-edition
May 20, 2025, 10:05 PM@snep@y.diskcat.com @manawyrm@chaos.social that is actually really cool, I guess some effort makes that possible. I wonder if there are enough backported drivers and stuff to daily drive it on modern hardware (ignoring the security and lack of software, I mostly mean if it's fully functional on modern hardware)
May 20, 2025, 10:08 PM@subroutine @manawyrm Honestly, I'm pretty sure with the OneCoreAPI and all updates from LegacyUpdate installed, you could daily an XP install!
This system is, driver-wise, fully supported, since 4th Gen Intel Core i/Xeon E3 v2 platforms still had drivers for the chipset available! Granted, it's not *modern* modern, but still pleeenty fast and usable. I do want to try a PAE patch to allow more RAM to be usable even on 32bit Windows, but I've heard it can be quite unstable. Hmm...
@snep @subroutine I have the latest Nvidia GTX GPU that was supported on XP and I also have a big 16core Ryzen CPU on a mainboard with CSM support. One day I‘ll need to try and get this going, but it‘s very, very far back on my project list…
May 21, 2025, 5:33 AM@manawyrm @subroutine Understandable!
The last supported GTX is probably something in the 9xx line of cards, right? Or was there ever a driver for GTX 10xx cards?
@snep @subroutine GTX7xx series is the last one
May 21, 2025, 4:52 PM@manawyrm Ohh interesting, just had a peek at NVIDIAs drivers page, I was thinking 9xx since NVIDIA is offering a driver for XP for the GTX950 and GTX960, but /not/ the GTX970 or higher, even though they're the same GPU architecture generation. Weird :neocat_think:
@snep iiiinteresting! I've tried that with the 980 (because I have one here)...
Now I _really_ want to try that and see if the driver really doesn't work.
May 21, 2025, 5:00 PM@manawyrm Apparently it takes a few INF file edits to include the 970's and up device IDs in the driver package, but according to The Internet™, it should then work and be fully supported! If you do end up testing it out, let me know how well it worked :3
May 20, 2025, 11:20 PM@snep @subroutine @manawyrm but it already says to have PAE enabled?
May 21, 2025, 5:37 AM@littlefox Yup, but even with that, it still can only address 3.4 GiB of RAM out of the box! Thus, the few existing PAE patches come into play to allow up to 128 GiB of usable memory, even if individual applications are still limited to 3.4 GiB
