What’s Inside?
System Board Technical Description
SATA (Serial Attached ATA)
The PCH is compatible with the Serial ATA Specification, Version 2.5.
Includes Serial ATA II: Extensions to Serial ATA 1.0, Revision 1.0, and
supports independent DMA operation on up to three ports with data
transfer rates of up to 3.0 Gb/s. Each channel consists of a transmit and
receive pair.
SATA0 and SATA1 are routed to CN16 along to support the SATA HDD
Card.
SATA2 is reserved for an on-board SATA to IDE Bridge chip found on
Revision D System Boards, but not available on the 2015 Revision C
System Board. Appears as ATA HDD2: in the BIOS Boot Order or F5 Boot
Menu.
SATA3 is routed to CN17 for use by the SATA CF Riser Card used on
Revision C boards. Appears as ATA HDD3: in the BIOS Boot Order or F5
Boot Menu.
PCI Bus
The PCI Bus conforms to the PCI Local Bus Specification, Version 2.3.
The QM57 integrates up to four external PCI Bus masters. PCI Bus signals
are routed to CN13, the Mini-PCI expansion slot.
Ethernet
The QM57 integrates a Gigabit Ethernet Controller that is compatible with
the Intel 82867 Gigabit LAN Platform Connect Device.
The QM57 integrated GbE controller supports multi-speed operation of
10/100/1000 Mb/s. The interface can operate in full duplex at all supported
speeds or half-duplex at 10/100 Mb/s and complies with the IEEE 802.3x
Flow Control Specification.
HD Audio
The QM57 contains an High Definition Audio (HDA) controller that
communicates with an external codec over the Intel High Definition Audio
serial link. The HDA protocol is controller synchronous, based on a
24MHz Bit Clock sent by the QM57 HDA controller.
The input and output streams, including command and PCM data, are
isochronous with a 48Khz frame rate. The QM57 implements four DMA
output engines and four DMA input engines. The output DMA engines
move digital data from system memory to the D-A converter in the codec.
The input DMA engines move digital data from the A-D converter in the
codec to system memory.
