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 775-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 provide 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, P4BWAcomes 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 provide 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.
