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.
