| 6 | comments or corrections. |

| 13 | 1. State of Supported Hardware |
| 14 | |
| 15 | PowerSurge Architecture - tested on UMAX s900, Apple 9600 |
| 16 | The second processor on this machine boots up just fine and |
| 17 | enters its idle loop. Hopefully a completely working SMP kernel |
| 18 | on this machine will be done shortly. |
| 19 | |
| 20 | The code makes the assumption of only two processors. The changes |
| 21 | necessary to work with any number would not be overly difficult but |
| 22 | I don't have any machines with >2 processors so it's not high on my |
| 23 | list of priorities. If anyone else would like do to the work email |
| 24 | me and I can point out the places that need changed. If you have >2 |
| 25 | processors and don't want to add support yourself let me know and I |
| 26 | can take a look into it. |
| 27 | |
| 28 | BeBox |
| 29 | BeBox support hasn't been added to the 2.1.X kernels from 2.0.X |
| 30 | but work is being done and SMP support for BeBox is in the works. |
| 31 | |
| 32 | CHRP |
| 33 | CHRP SMP works and is fairly solid. It's been tested on the IBM F50 |
| 34 | with 4 processors for quite some time now. |
