required every time the system boots), Setup (a password is required every time Setup is executed), or Disabled. See page for instructions on changing a
password.
Fast Gate A20 Option
Gate A20 controls the ability to access memory addresses above 1 MB by enabling or disabling access to the processor address line A20. To remain XT-
Compatible and be able to access conventional memory (from 0 - 1024K), address line A20 must always be low, so Gate A20 must be disabled. However, some
software programs both enter protected mode and shut down through the BIOS. For this software, Gate A20 must be constantly enabled and disabled via the
keyboard controller, which can slow processing considerably. Fast Gate A20 is an alternate method of enabling Gate A20 that permits access to memory
addresses above 1 MB. Use Fast Gate A20 to speed Gate A20 enabling and disabling, which in turn speeds up programs that constantly change from addressing
conventional memory to addressing memory addresses above 1 MB. For example, enabling this option makes programs such as network operating systems
execute faster. The settings are Enabled or Disabled.
