NumLock
This setting is to set the Num Lock status when the system is powered on. Setting to
[On] will turn on the Num Lock key when the system is powered on. Setting to [Off]
will allow users to use the arrow keys on the numeric keypad.
PState Configuration
ACPI P-state (Performance) control algorithm
’
s goal is to optimize the runtime power
consumption without significantly impacting performance. The algorithm dynamically
adjusts the processor frequency such that it is just high enough to service the SW
execution load. Operating point selection is done by the OS power management
algorithms (OSPM) based on the CPU load observed over a window of time. Once the
target point is set, the CPU is expected to modify its operating voltage and frequency
to match the OSPM's request.
Halt On Error
The setting determines whether the system will stop if an error is detected at boot.
M emory Controller Options
DRAM Bank Interleave
Interleaved memory is system memory divided into two or more sections. Set-
ting to [Enabled] allows memory to be accessed faster since each section of
memory is capable of being utilized at once.
Node Interleave
AMD Opteron CPU supports a mode called node interleave. W hen node inter-
leave is
disabled , the memory controller maps the local memory of each pro-
cessor to a single contiguous range of physical addresses. This allows the
operating system to map user data to local memory, whenever possible, to
allow programs to access data the most rapidly. W hen node interleave is
enabled , physical addresses are partitioned into 4KB blocks, and alternated
