TP 560/E - 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.

When you enable ECP as the printer operating mode by the ThinkPad Configuration program, one of the choices (including "disabled") must be selected.
