132 | There are four families of PowerPC chips supported. The more common | |

134 | versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the AMCC | |
135 | embedded versions (403 and 405) and the high end 64 bit Power | |
136 | processors (POWER 3, POWER4, and IBM PPC970 also known as G5). | |
650f3289 GL |

138 | This option is the catch-all for 6xx types, including some of the | |
139 | embedded versions. Unless there is see an option for the specific | |
140 | chip family you are using, you want this option. | |
141 | ||
142 | You do not want this if you are building a kernel for a 64 bit | |
143 | IBM RS/6000 or an Apple G5, choose 6xx. | |
