•• •    Boot Sector Virus Protection 
If it is set to enable, the category will flash on the screen when there is any attempt to write 
to the boot sector or partition table of the hard disk drive. The system will halt and the 
following error message will appear in the mean time. You can run anti-virus program to 
locate the problem.   
Enabled  Activate automatically when the system boots up causing a warning 
message to appear when anything attempts to access the boot sector or 
hard disk partition table 
Disabled  No warning message to appear when anything attempts to access the 
boot sector or hard disk partition table. (Default Value)
 
•
•• •  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 CPUs memory 
address map. 
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
