Chapter1 <Introduction>

1.1 <Product Overview>

2807870 is the motherboard with last Intel desktop technology with Mini-ITX form factor.
Based on Intel® Q35 and ICH9DO, the board integrates a new Core2 Quad / Core 2 Duo
processor 775-pin socket, DDR2 memory socket, Intel® Graphic Media Accelerator 3100

technology, Serial ATA II with RAID function for a powerful desktop system.

Intel

® LGA775 processor

The Intel® Core2 Quad / Core 2 Duo processor now comes with a new form factor with
775-pin PLGA package, for 800/1066/1333MHz front-side-bus, 4MB L2 cache, for 65nm
and 45nm manufacturing technology, the PLGA processor without pin header on solder side
can make user installing the processor on the socket easier.

Intel

® Q35 and ICH9DO chipset

The Intel Q35 integrates DDR2 667/800MHz for memor y, and Graphic Media Accelerator
(GMA) 3100 technology for new graphic engine. It can provide up to 384MB of frame buffer
when you install over 1GB of system memory. The ICH9DO integrates with up to 6 USB2.0
interfaces and serial ATA II interface with RAID function.

Flexible Extension Interface

2807870 provides one PCIE slot for graphics card, it also can support
PCI Express by 1/ 16 LAN card or others device and one Mini-PCI socket.
