AMD Athlon CPU support
From Haiku Max Wiki
The Athlon CPUs start SSE differently than Pentium CPUs causing BeOS to reboot when the kernel is not patched. To patch the Kernel to run on Athlons you have to edit the kernel with a hex editor and replace the second instance of the string GenuineINTEL with AuthenticAMD. Note that the string must be absolutely identical, case does matter, otherwise it will not work.
