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.
Select the Execute-Disable Bit Capability or Front Operation Panel item to
make changes. Please refer to the instructions displayed on the screen.
Available Makes the processor’s Execute-Disable Bit Capability
available for use.
Not Available Disables the processor’s Execute-Disable Bit
Capability so that it is not available for use. (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, Device
Manager and so forth.
