5.2 Memory Area

The first 640 kB of DRAM are used as main memory. Using DOS, you can address 1MB of memory directly. The 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.
