Memory configuration
BIOS automatically detects, sizes, and initializes the memory array,
depending on the type, size, and speed of the installed DIMMs, and reports
memory size and allocation to the system via configuration registers.
In a 4 GB configuration, a small part of memory (typically 32 MB) is not
remapped above 4 GB. If the OS does not support more than 4 GB of
physical memory, this small part of the memory is effectively lost.
Removing the memory module
The memory module must be removed before you can change the memory
configuration. See “Operating systems” on page 41 for memory size and
requirements.
1. Observe the safety and ESD precautions in “Static electricity
precautions” on page 2.
2. Remove the access cover (see “Opening the system” on page 2).
