Direct Cache Access (DCA Support)
Select Enabled to use Intel's DCA (Direct Cache Access) Technology to improve
data transfer efficiency. The options are Enabled and Disabled.
DCA Prefetch Delay
A DCA prefetcher is used with a TOE (TCP/IP Offload Engine) adapter to prefetch
data to shorten execution cycles and to maximize data processing efficiency.
Prefetching data too frequently can saturate the cache directory and delay neces-
sary cache access. This feature reduces or increases the frequency of system data
prefetching activities. The options are Disable, 16, 24, 32, 40, 48, 56, 64, 72, 80,
88, 96, 104, and 112.
X2APIC
Select Enable to activate APIC (Advanced Programmable Interrupt Controller) sup-
port. The options are Enabled and Disabled.
Intel® Virtualization Technology (Available when supported by the CPU)
Select Enabled to support Intel Virtualization Technology, which will allow one
platform to run multiple operating systems and applications in independent parti-
tions, creating multiple "virtual" systems in one physical computer. The options
are Enabled and Disabled.
Note: If a change is made to this setting, you will need to reboot the
system for the change to take effect. Refer to Intel's website for detailed
information.
