There are five families of 32 bit PowerPC chips supported.
The most common ones are the desktop and server CPUs (601, 603,
604, 740, 750, 74xx) CPUs from Freescale and IBM, with their
- embedded 52xx/82xx/83xx/86xx counterparts.
+ embedded 512x/52xx/82xx/83xx/86xx counterparts.
The other embeeded parts, namely 4xx, 8xx, e200 (55xx) and e500
(85xx) each form a family of their own that is not compatible
with the others.
If unsure, select 52xx/6xx/7xx/74xx/82xx/83xx/86xx.
