On which processors will ReactOS run?
ReactOS currently only supports the x86 processor architecture, although a PowerPC and AMD port has begun. ReactOS will run on Intel(R) Pentium(R) x64, Intel Xeon(R) x64, AMD(R) Athlon(R) x64 and AMD Opteron(R) processors in 32-bit mode, but the 64-bit functionality of these processors is not currently supported. See Compatibility Database for a list of supported device drivers.
