While installing programs, if you load some of them into the Upper Memory Area

(UMA), this helps free up some conventional memory for use by your application.

The following overview should provide some insight into how memory is orgaĆ

nized and what each part is for.
To better understand the usage of these memory areas, refer to the diagram beĆ

low, while reading the information that follows.

Figure BĆ1

Conventional Memory - That area of memory in which most DOS applications

run.  Other programs that could reside there include portions of DOS and any

programs called using a device=" or install=" line in CONFIG.SYS or any proĆ

grams that are not executed with a loadhigh" from AUTOEXEC.BAT.  ConvenĆ

tional memory can be up to 640 KB.
UMA - Just above conventional memory.  UMA provides memory for system

hardware.  Any memory not used by the system is usable.  The

device=elanump.sys. . ." and DOS=UMB" lines, in CONFIG.SYS, provide access

to UMA.  After ELANUMP.SYS is loaded and DOS=UMB" specified, other

drivers are loaded into UMA using devicehigh=" in CONFIG.SYS or loadhigh"

in AUTOEXEC.BAT. This combination of conventional and upper memory

consists of 1 MB, meaning there is 384 KB of memory for UMA.
