TP 760E/ED/EL/XD/XL,765 - Hardware resource assignments

Applicable to: World-Wide

The figure below shows the memory map for a correctly functioning system. Memory can be mapped differently if POST detects an error in system board memory or TR/CMOS RAM. In the figure, the variable x represents the number of 1-MB blocks of system board memory starting at or above the hex 100000 boundary.
