COMe-mSP1 / System Resources
5.2 Memory Area
The first 640 kB of DRAM are used as main memory. Using DOS, you can address 1 MB of memory directly. Memory area
above 1 MB (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.
