Chapter1 <Introduction>

1.1 <Product Overview>

P4BWA is the motherboard with last Intel desktop technology with industrial motherboard

form factor. Based on Intel® Q965 and ICH8DO, the board integrates a new Core 2 Quad
processor 775-pin socket, DDR2 memory slot, Intel® Graphic Media Accelerator 3000
technology, PCI express interface and Serial ATA II with RAID function for a powerful
desktop system.

Intel® LGA775 processor

The Intel® Core 2 Quad processor now comes with a new form factor with 7 75-pin PLGA
package, for 533/800/1066MHz front-side-bus, 4MB L2 cache, and for 65nm manufacturing
technology, the PLGA processor without pin header on solder side can make user installing
the processor on the socket easier.

Intel® Q965 and ICH8DO chipset

The Intel Q965 integrates DDR2 533/667/800MHz for memory, and Graphic Media
Accelerator (GMA) 3000 technology for new graphic engine. It can provid e up to 256MB of
frame buffer when you install over 512MB of system memory. The ICH8DO integrates with
up to 10 USB2.0 interfaces (6 ports for P4BWA) I/O panel, and serial ATA II interface with
RAID function.

Dual Intel 82573L Gigabit LAN

Dual Gigabit LAN with Intel 82573L, P4BWA comes with a powerful network function for the
system that requires large transfer data of NAS system or Server platform.

PCI-Express interface

P4BWA integrates one x16 and x4 PCI-Express interface, it can provid e up to 8GB/s of
bandwidth, which AGP 8x can only provide up to 2GB/s.

Multimedia interfaces

P4BWA also integrates 7.1 channel HD audio, Mini-PCI, PCI and ISA interface, for these

flexible function, system integrator can built more powerful systems for many applications.

P4BWA User’s Manual

3.2 <SATA RAID Configuration>

The board integrates Intel® ICH8DO 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 driv e 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.
