Note: Memory between 4 GB and 4 GB minus 512 MB is not be accessible for use by the
operating system and may be lost to the user. This area is reserved for BIOS, APIC
configuration space, PCI adapter interface, and virtual video memory space. This means that if
4 GB of memory is installed, 3.5 GB of this memory is usable. The chipset should allow the
remapping of unused memory above the 4 GB address, but this memory may not be accessible
to an operating system that has a 4 GB memory limit.
The minimum memory installed is 256 MB (one 256 MB DIMM).
3.5.3 I
2
C Bus
To boot the system, the system BIOS uses a dedicated I
2
C bus to retrieve DIMM information
needed to program the MCH memory registers.
