ENABLE: Allow
remapping of
overlapped PCI memory
above the total
physical memory.
DISABLE: Do not allow
remapping of memory.
► Memory Remap Feature
This item is used to enable/disable memory remapping around memory hole.
PCI doesn't actually care much which addresses are used, but by convention the PC platform
puts them at the top of the 32-bit address space. For many years it wasn't possible or practical to
put that much RAM into a PC. But now it is, so it's up to the memory controller and host bridge to
figure out what to do. Many systems cause that high RAM to simply be ignored, resulting in the
loss of effective RAM. More complex systems will take the RAM that would occupy that 3.5-4GB
address space and re-map it into the 4.0-4.5GB address space. The RAM doesn't care because
it's just an array of storage cells, it's up to the memory controller to associate addresses with
those storage cells. Of course, that only works if you're using a 64-bit (or 32bit physical address
extension (PAE) enabled) OS that can deal with physical addresses larger than 32 bits. Once
this option is enabled, BIOS will display the true size of memory installed.
► Initate Graphic Adapter
This item is used to select which graphics controller is used as the primary boot device.
► IGD Graphics Mode Select
This item is used to select the amount of system memory used by the Internal graphics device.
► PEG Port
This item is used to disable the PCI Express graphics port or let it be auto-detected.
► PEG Force GEN1
This item is used to force PCI Express graphics port to work at GEN1 speed.
► SLP_S4# Min. Assertion Width
SLP_S4# is a signal for power plane control. This signal shuts off power to all non-critical
systems when in the S4 (Suspend to Disk) or S5 (Soft Off) state.
This setting indicates the minimum assertion width of the SLP_S4# signal to ensure that the
DRAMs have been safely power-cycled. Setting values are: [4 to 5 seconds], [3 to 4 seconds],
[2 to 3 seconds], [1 to 2 seconds].
