Limit CPUID Maximum
The CPUID instruction of some newer CPUs will return a value greater than
3. The default is Disabled because this problem does not exist in the Win-
dows series operating systems. If you are using an operating system other
than Windows, this problem may occur. To avoid this problem, enable this
field to limit the return value to 3 or lesser than 3.
Execute Disable Bit
When this field is set to Disabled, it will force the XD feature flag to always
return to 0. XD 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.)
Hardware Prefetcher
Tuns on or off the Mid level Cache (L2) streamer prefetcher. The options
are Enabled and Disabled.
Adjacent Cache Line Prefetch
Turns on or off prefetching of adjacent cache lines. The options are En-
abled and Disabled.
Intel Virtualization Technology
When this field is set to Enabled, the VMM can utilize the additional hard-
ware capabilities provided by Vanderpool Technology.
Power Technology
Configures the power management features.
