￿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.

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.

ExtendedMemory

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.
