DCA Technology
When set to Enabled, this feature accelerates the performance of TOE devices.
Note: A TOE device is a specialized, dedicated processor that is installed
on an add-on card or a network card to handle some or all packet process-
ing of this add-on card. For this motherboard, the TOE device is built inside
the ESB 2 South Bridge chip. This feature is supported only by some types
of processors. The options are Enabled and Disabled.
DCA Prefetch Delay
A DCA (Direct Cache Access) Prefetch is used with TOE components to prefetch
data in order to shorten execution cycles and maximize data processing effi ciency.
Prefetching too frequently can saturate the cache directory and delay necessary
cache accesses. This feature reduces or increases the frequency the system
prefetches data. The options are [8], [16], [32], [40], [48], [56], [64], [72], [80], [88],
[96], [104], [112], [120]
