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 memory, 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.

Chapter 3 <System Configuration>

3.1 <SATA configuration>

SATA Mode:

This option can let you select whether the Serial ATA hard drives would work under normal

IDE mode or RAID mode. The RAID mode need more than one HDD is applied.

33

2807870 User’s Manual

3.2 <SATA RAID Configuration>

The board integrates Intel® ICH9DO with RAID function for Serial ATA II drives, and supports the configurations below:

RAID 0 (Stripping): Two hard drives operating as one drive for optimized data R/W performance. It needs two unused drives to build this operation.

RAID 1 (Mirroring): Copies the data from first drive to second drive for data security, and if one drive fails, the system would access the applications to the workable drive. It needs two unused drives or one used and one unused drive to build this operation. The second drive must be the same or lager size than first one.

RAID 5 (striping with parity)

A RAID 5 array contains three or more hard drives where the data is divided into manageable blocks called strips. Parity is a mathematical method for recreating data that was lost from a single drive, which increases fault-tolerance. The data and parity are striped across all the hard drives in the array. The parity is striped in a rotating sequence to reduce bottlenecks associated with the parity calculations.

RAID 10 (RAID 0+1)

A RAID 10 array uses four hard drives to create a combination of RAID levels 0 and 1. The data is striped across a two-drive array forming the RAID 0 component. Each of the drives in the RAID 0 array is then mirrored by a RAID 1 component.

Intel Matrix Storage Technology: This technology would allow you to use RAID 0+1 mode on only two drives (4 drives needed on traditional RAID 0+1). It will create two partitions on each hard drive to simulate RAID 0 and RAID 1. It also can let you modify the partition size without re-formatted.

For more information of Intel Matrix Storage Technology, please visit Intel’s website.

If you need to install an operation system on the RAID set, please use the driver disk attached in the package when it informs you to obtain the RAID drivers.

BIOS Setup:

On-Chip Video Memory Size: This option combines three items below for setup.

On-Chip Frame Buffer Size:

This item can let you select video memory which been allocated for legacy VGA and SVGA graphics support and compatibility. The available option is 1MB and 8MB.

Fixed Memory Size:

This item can let you select a static amount of page-locked graphics memory which will be allocated during driver initialization. Once you select the memory amount, it will be no longer available for system memory.

DVMT Memory Size:

This item can let you select a maximum size of dynamic amount usage of video memory, the system would configure the video memory depends on your application, this item is strongly recommend to be selected as MAX DVMT.

Appendix C <Programming GPIO’s>

The GPIO’can be programmed with the MSDOS debug program using simple

IN/OUT commands.The following lines show an example how to do this.

GPIO0…..GPIO7 bit0……bit7

-o 2E 87 ;enter configuration

-o 2E 87

-o 2E 07

-o 2F 09 ;enale GPIO function

-o 2E 30

-o 2F 02 ;enable GPIO configuration

-o 2E F0

-o 2F xx ;set GPIO as input/output; set ‘1’ for input,’0’for output

-o 2E F1

-o 2F xx ;if set GPIO’s as output,in this register its value can be set

Optional :

-o 2E F2

-o 2F xx ; Data inversion register ; ‘1’ inverts the current valus of the bits ,’0’ leaves them as they are

-o 2E 30

-o 2F 01 ; active GPIO’s

For further information ,please refer to Winbond W83627DHG datasheet.
