Mem ory
This cate gory is dis play only and is de ter mined by the BIOS POST (Power On Self Test).
Base Mem ory
The POST rou tines in the BIOS will de ter mine the amount of base (con ven tional) mem ory in stalled
in the sys tem The value of the base mem ory is typi cally 640K for sys tems with a Mega byte of mem ory
or greater.
Ex tended Mem ory
The BIOS de ter mines how much ex tended mem ory is pres ent dur ing the POST. This is the amount
of mem ory lo cated above 1MB in the CPU's mem ory ad dress space.
Other Mem ory
This re fers to mem ory lo cated in the 640K to 1024K ad dress space. This is mem ory that can be used
for dif fer ent ap pli ca tions. DOS may use this area to load de vice driv ers and TSRs to keep as much base
mem ory free as pos si ble for ap pli ca tion pro grams. The most com mon use of this area is for shadow
RAM.
