X8SIA/X8SIA-F User's Manual

Note: Due to memory allocation to system devices, the amount of memory that

remains available for operational use will be reduced when 4 GB of RAM is

used. The reduction in memory availability is disproportional.

For Microsoft Windows users: Microsoft implemented a design change in Win-

dows XP with Service Pack 2 (SP2) and Windows Vista. This change is specic

to the Physical Address Extension (PAE) mode behavior which improves driver

compatibility. For more information, please read the following article at Microsoft’s
