ReactOS Now Running On ARM64 In Experimental Form
ReactOS has achieved experimental support for ARM64, expanding its compatibility beyond i586 and AMD64 architectures. This milestone allows ReactOS to boot on ARM64 systems, specifically targeting Apple ARM64 processors through QEMU. The project continues to work towards implementing binary compatibility for Windows applications and drivers.
- ▪ReactOS is an open-source project aimed at providing binary compatibility for Microsoft Windows programs and drivers.
- ▪The new ARM64 support was made possible by the efforts of an open-source contributor over recent months.
- ▪The experimental build requires a UEFI compatible system with GICv2 or GICv3 enabled.
