How to Enable the Memory Remapping on an Asus P5B

Updated March 23, 2017

A computer's basic input output system (BIOS) is the structure underlying all the computer's functions. The BIOS is the skeleton programming over which the operating system, such as Windows, is layered. It's responsible for core computer functions. Each motherboard manufacturer uses a different BIOS. Therefore, each BIOS requires a different access key. Computer users who run 32-bit operating systems often enable the memory remapping feature in BIOS, to allow a greater capacity of RAM to be used.

Shut down the computer. Boot the system.

Press "DEL" as the system is booting. Some ASUS systems use "INS" or "F2" for entering system set-up. If "DEL" does not work, shut down and reboot the system while trying "INS" or "F2."

Press "Tab" key to move to Advanced Menu.

Use the Down arrow key to scroll down and highlight "Advanced Chipset Features." Press "Enter."

Highlight "Northbridge Configuration" using the arrow keys. Press "Enter."

Highlight "Memory Remap Feature" using the arrow keys. Press "Enter."

Press "+" or "-" to change the option to "Enabled." Press "ESC" to exit BIOS.


Use arrow keys and tab key to navigate in BIOS.
