|  | This document and the related code was written by me |

|  | comments or corrections. |

|  | 1. State of Supported Hardware | 
|  |  | 
|  | PowerSurge Architecture - tested on UMAX s900, Apple 9600 | 
|  | The second processor on this machine boots up just fine and | 
|  | enters its idle loop.  Hopefully a completely working SMP kernel | 
|  | on this machine will be done shortly. | 
|  |  | 
|  | The code makes the assumption of only two processors.  The changes | 
|  | necessary to work with any number would not be overly difficult but | 
|  | I don't have any machines with >2 processors so it's not high on my | 
|  | list of priorities.  If anyone else would like do to the work email | 
|  | me and I can point out the places that need changed.  If you have >2 | 
|  | processors and don't want to add support yourself let me know and I | 
|  | can take a look into it. | 
|  |  | 
|  | BeBox | 
|  | BeBox support hasn't been added to the 2.1.X kernels from 2.0.X | 
|  | but work is being done and SMP support for BeBox is in the works. | 
|  |  | 
|  | CHRP | 
|  | CHRP SMP works and is fairly solid.  It's been tested on the IBM F50 | 
|  | with 4 processors for quite some time now. |
