Execute-Disable Bit Capability
This setting, which is displayed on the first page of the setup screen,
configures the Execute-Disable Bit function of the CPU. This function is
specific to Intel processors and, when activated, helps to reduce security
threats to the computer by preventing certain classes of malicious “buffer
overflow” attacks when combined with a supporting operating system such
as Windows XP.
Available Makes the Execute-Disable Bit Capability
useable (Available).
Not Available Disables the Execute-Disable Bit Capability
(Not available) (Default).
System configuration changes, other than changes to this setting, should
be made within Windows by using applications such as TOSHIBA HW
Setup, TOSHIBA Password Utility, TOSHIBA Power Saver, Windows
Device Manager and so forth.
