PCWS 2015 BIOS
Advanced
Serial ATA Port 4 and 5 [Not Used Available]
SATA Port 4 and 5 connectors are not implemented. The selections are not
available.
IMC Configuration
The IMC (Integrated Memory Controller) accesses the North Bridge Common
Configuration, Video, Arrandale and IGD Configuration. This grouping of
apparently unrelated menus is due to the fact that both the Memory and
Graphics controllers are located in the same package as the i5 or Celeron
Processor.
> NB Common Configuration
The ‘North Bridge’ Common Configuration Menu allows access to a single
field, listed below.
VT for Directed I/O (VT-d) [Disabled]
Enable/Disable Intel (R) Virtualization Technology for Directed I/O
(VT-d) by reporting the I/O Device assignments to VMM through
DMAR ACPI Tables.
> Video Configuration
The following video BIOS fields do not apply to the PCWS 2015.
Always Enable PEG [Disabled]
PEG0 (Processor PCI Express Port 0) are PCI Express lanes connected
directly to the processor and intended for ‘graphics card attach.’
On a typical desktop PC, the PEG0 lanes are routed to a PCIe x16
connector, for installation of a 2D/3D video card.
PEG X1 Mode [Disabled]
Forces the Processor PCI Express Graphics lanes into the X1 transfer
mode.
> Arrandale Configuration
PEG0 Configuration [Disabled]
Enable or Disable PEG0 Active Power State Management.
