Demand Scrub
Demand Scrubbing is a process that allows the CPU to correct correctable
memory errors found on a 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 error, the error is corrected and sent to the requestor (the original
source). Memory is updated as well. Select Enable to use Demand Scrubbing
for ECC memory correction. The options are Enable and Disable.
Device Tagging
Select Enable to support device tagging. The options are Disable and Enable.
