BIOS Setup
see all of the (64-bit addressed) main memory although with a 32-bit address
bus you can only address a 32-bit address space. It is a MMU that translates
DMA virtual addresses to real physical addresses.
Size
This setting specifies the memory size for IOMMU.
ACPI SRAT Table
The Static Resource Affinity Table (SRAT) can be used to describe the physical
location of processors and memory in large-scale systems (such as CC-NUMA)
to the Microsoft W indows Server 2003 operating system, allowing threads and
memory to be grouped in an optimal manner.
ECC Options
ECC Mode
If all memory in the system supports ECC, enabling this will initial scrub DRAM
and enable system requests to DRAM to be checked and/or corrected.
ECC Error Checking
This setting enables/disables ECC (Error Correction Code) checking, a method
of checking the integrity of data in DRAM. ECC provides more elaborate error
detection than parity; ECC can detect multiple-bit errors and can locate and
correct single-bit errors.
ECC Error Log
This setting logs the ECC error.
Chipkill
Chipkill is a new Advanced ECC (Error Correction Code) memory technology
that protects servers from system downtime caused by memory failures.
