North Bridge Confi guration
This feature allows the user to confi gure the North Bridge Chipset settings.
Crystal Beach/DMA
This feature uses the Intel I/O AT (Acceleration Technology) to accelerate 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 processing of this add-on card. For this motherboard, the TOE
device is built inside the ESB 2 South Bridge chip. The options are Enabled
and Disabled.
MCH (Memory Controller Hub) Branch Mode
This feature allows the user to decide how the two memory branches operate.
System address space can either be interleaved between the two branches
or sequencing from one branch to another. Mirror mode offers data correction
by maintaining two copies of data in two branches. Single Channel 0 allows a
single DIMM population during system manufacturing. The options are Branch
Interleave , Branch Sequencing, Branch Mirroring, and Single Channel 0.
Patrol Scrubbing
Scrubbing is a process that allows the North Bridge to correct correctable
memory errors found on FBD memory modules. Select Enabled to use Patrol
Scrubbing, a background ECC memory correction activity initiated by the North
Bridge to fi nd and correct memory errors by scanning all memory modules
doing simulated "READs" while checking for ECC errors. When an ECC error
is detected during this process, it is logged as a Patrol error. A correctable
error is corrected and written back into memory. The options are Enabled
and Disabled.
Demand Scrubbing
Scrubbing is a process that allows the North Bridge to correct correctable
memory errors found on an FBD memory module. When the CPU or I/O issues
a demand- read command, and the read data from memory turns out to be
a correctable ECC, it is corrected and sent to the original source. Memory is
updated as well. Select Enabled to use Demand Scrubbing for ECC memory
correction. The options are Enabled and Disabled.
Branch Dependent Sparing
Select Enabled to use the feature of branch-dependent sparing. The options
are Enabled and Disabled .
