Memory Map
The coolMONSTER/PM processor modules can support up to 2048MB of memory. The first 640KB of DDR-
SDRAM are used as main memory.
Using DOS, you can address 1MB of memory directly. Memory area above 1MB (high memory, extended
memory) is accessed under DOS via special drivers such as HIMEM.SYS and EMM386.EXE, which are part
of the operating system. Please refer to the operating system documentation or special textbooks for
information about HIMEM.SYS and EMM386.EXE.
Other operating systems (Linux or Windows versions) allow you to address the full memory area directly.
