Memory Resources
The general memory layout is shown in paragraph 3.2.1. The configuration of the memory
layout is done by programming processors internal configuration registers and board
configuration registers (see paragraph 4.2.3). This is done completely by the BIOS on system
startup and must not be changed during operation. For operating systems requiring memory
configuration (e.g. Windows CE) the memory layout shown in paragraph 3.2.1 must be
considered.
