A.2 Memory
Area
The first 640 kB of DRAM are used as main memory. DOS 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.
Other operating systems (Linux or Windows
®
versions) allow you to address the full memory area directly.
