3.2-D. Memory
You cannot change any values in the Memory fields, as they are shown only for your information. The
fields show the total installed random access memory (RAM) and amounts allocated to base, extended,
and other memory. RAM is the computer’s working emmory, where the computer stroes programs and
data currently being used, so that they are accessible to the CPU. RAM is counted in kilobytes (KB:
approximately one thousand bytes) and megabytes (MB: approximately one million bytes). Modern per-
sonal computers may contain up to 128, 256 MB, or more.
3.3 Advanced BIOS Features
This section may allow the user to alter certain settings that affect the way their computer boots up,
checks CPU cache, and other advanced features.
Please note that you should not alter settings in
this BIOS section unless you are absolutely sure that you know what you are doing.
(continued on next page)
Extended memory
Base Memory
Typically 640KB. Also called conventional memory. The DOS
operating system and conventional applications use this area.
Other Memory
Above the 1MB boundary. Early IBM personal computers could
not use memory above 1MB, but current PCs and their software
can use extended memory.
Between 640KB and 1MB; often called high memory. DOS may
load terminate-and-stay (TSR) programs in this area, such as
device drivers, to free as much conventional memory as possi-
ble for applications. Lines in your config.sys file that start with
loadhigh
, load programs into high memory, for example.
