The regression has been identified. We hope to see #ReactOS soon running on that PC again ^^

Pleasantly surprised to discover late-2023 @reactos runs even on a 166MHz Pentium with no MMX and only 64MB RAM. Too little RAM to unpack installers, however, and more recent builds won't even load freeldr stage 2 on this hardware.

We are pleased to see #ReactOS working on this Toshiba V3100, with Intel GMA i810 graphics drivers! ^^

Never thought I’d see @reactos running this well on a late 90s Toshiba desktop with all the proper drivers being installed. Yes that’s vintage Intel GMA graphics (i810) working too.

And this is #ReactOS ARM64 running on Raspberry Pi 5! Back in 2022-23, our ARM64 port was only able to produce user-mode executables. While being in a experimental state, we could finally see ARM64 in action!!

Well it actually does, not natively on Apple yet. This is on Raspberry Pi 5, pics from ReactOS Discord.

For 8 months, our contributor @sidihmeed has been working on getting #ReactOS ARM64 port to boot. Here's the first success! Being still in an experimental state, you may want to try it.

The build requires UEFI compatible ARM64 with GICv2 or v3 enabled and will support boards starting from ARMv8-A and upward, with the special case of RPI5 that have his own interupt chip.
