Base Memory
The POST of the BIOS will determine the amount of
base (or conventional) memory installed in the system.
The value of the base memory is typically 640KB.

Halt On
This category determines whether the computer will stop if an error is
detected during power up.
No errors

This category is for display only and is determined by the POST (Power
On Self Test) of the BIOS. You have four display choices.
BIOS Configuration
Other Memory
This refers to memory located in the 640KB to 1024KB
address space. This memory can be used for different
applications. DOS uses this area to load device drivers in
order to keep as much conventional memory free for
application programs as possible. Often called “high
memory.”
Extended Memory
The BIOS determines how much extended memory is
present during the POST. This is the amount of memory
located above 1MB in the CPU's memory address map.
