2.6 Debug Monitor Memory Map
The Debug Monitor image is loaded from the system ROM into memory at physical
address 0 by the SROM initialization code. At startup, the Debug Monitor
determines the amount of memory present in the motherboard based on parameters
that are passed in from the SROM initialization code. One of these parameters
determines the top of main memory. Refer to your motherboard’s user’s manual for
more information about the SROM initialization code and supported memory
configurations.
Figure 2–1 shows the basic outline for the Debug Monitor memory map.
