Whenever the BIOS detects a non-fatal error the system will be
stopped and you will be prompted
All errors
The system boot will not be stopped for any error that may be
detected

Memory
The category is display-only which is determined by POST (Power On Self Test) of the
BIOS.
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 512 K for systems
with 512 K memory installed on the motherboard, or 640 K for systems with 640 K or
more memory installed on the motherboard.
Extended Memory
The BIOS determines how much extended memory is present during the POST. This
is the amount of memory located above 1 MB in the CPU's memory address map.
Expanded Memory
Expanded Memory in memory defined by the Lotus/Intel/Microsoft (LIM) standard as
EMS. Many standard DOS applications can not utilize memory above 640 K, the
Expanded Memory Specification (EMS) swaps memory which not utilized by DOS
with a section, or frame, so these applications can access all of the system memory.
Memory can be swapped by EMS is usually 64 K within 1 MB or memory above 1
MB, depends on the chipset design.
Expanded memory device driver is required to use memory as Expanded Memory.
Other Memory
This refers to the memory located in the 640 K to 1024 K address space. This is
memory that can be used for different applications. DOS uses this area to load
device drivers to keep as much base memory free for application programs. Most
use for this area is Shadow RAM.
