You can use this screen to select options for the CPU Configuration Settings. Use the up and
down < Arrow > keys to select an item. Use the < + > and < - > keys to change the value of
the selected option. A description of the selected item appears on the right side of the screen.
The settings are described on the following pages. An example of the CPU Configuration screen
is shown below.
Hyper-Threading Technology
This option enables/disables Intel® Hyper-Threading Technology.
Execute Disable Bit Capability
This is an Intel hardware-based security feature that can prevent certain classes of malicious
buffer overflow attacks when combined with a supporting OS (Windows Server 2003 SP1,
Windows XP SP2, SuSE Linux 9.2, RedHat Enterprise 3 Update 3.) . Set this value to Enabled/
Disabled.
Limit CPUID Maximum
When the computer is boots, the operating system executes its CPUID instruction to identify the
processor and its capabilities. Before it can do so, it must first query the processor to find out the
highest input value the CPUID recognizes. This determines the kind of basic information CPUID
can provide the operating system. This option allows you to circumvent problems with older
operating systems.
