Revision as of 21:01, 5 March 2019

Please update this page with the status of each CPU that is tested. AS YOU CAN SEE, THE LIST IS IN ALPHABETICAL ORDER. PLEASE KEEP IT THIS WAY.

Possible statuses

Status Description

Not tested No test has been performed
Failed Fails to work or crashes ReactOS
Run w/o result Run without fundamental functionality

Tested CPUs

Current state

i486 class CPUs

i486 class CPUs are not able to boot ReactOS due to their lack of the CMPXCHG8B instruction, Windows XP/2003 doesn't boot on them either, the ReactOS minimum requirements also state that a Pentium (a.k.a. i586) compatible CPU is needed to boot.

Note: The Cyrix 6x86 CPU appears to the system as if it's an i486 class CPU unless specifically triggered to act as an i586 CPU, however it does expose some i586 class instructions if properly triggered, so it appears in the i586 section.

i586 class CPUs

This list contains the Pentium/Pentium MMX family and all other i586 class CPUs. There is no guarantee that ReactOS will work as well on these CPUs as it does on newer chips as these CPUs lacks the SYSENTER/SYSCALL instruction and they generally lack i686 class instructions (like CMOV)

If you want to test ReactOS on an i586 class CPU, be prepared to update your motherboard's BIOS to make sure it is recent enough to boot ReactOS, as there is an issue that causes freeloader to be unable to boot on some ancient BIOS implementations.

i686 class CPUs

This list contains the Pentium Pro/II/III family and all other i686 class CPUs (without SSE2 support). It is generally guaranteed that ReactOS will work on these CPUs with some degree of functionality, Pentium Pro lacks the SYSENTER/SYSCALL instruction, they generally support i686 class instructions (like CMOV). All CPUs supports CMPXCHG8B.

If you want to test ReactOS on an i686 class CPU, be prepared to update your motherboard's BIOS to make sure it is recent enough to boot ReactOS, as there is an issue that causes freeloader to be unable to boot on some ancient BIOS implementations.
