Chapter1 <Introduction>
1.1 <Product Overview>
P4ELA is the motherboard with last Intel desktop technology with Micro ATX form factor.
Based on Intel®Q45 and ICH10DO, the board integrates a new Core 2 Quad / Core 2 Duo
Celeron processor 775-pin socket, DDR3 memory socket, Intel®Graphic Media Accelerator
4500 technology, Serial ATAII with RAID function for a powerful desktop system.
Intel®LGA775 processor
The Intel® Core 2 Quad / Core 2 Duo / Celeron processor now comes with a new form
factor with 775-pin PLGA package, for 800/1066/1333MHz front-side-bus, 12MB 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®Q45 and ICH10DO chipset
The Intel Q45 integrates DDR3 800/1066MHz for memory, and Graphic Media Accelerator
(GMA) 4500 technology for new graphic engine. It can provide up to 1024MB of frame
buffer when you install over 1GB of system memory. The ICH10DO integrates with up to 12
USB2.0 interfaces, and serial ATA II interface with RAID function.
PCI-Express interface
P4ELA integrates one x16 and one x4 PCI-Express interface, it can provide up to 8GB/s of
bandwidth.
Flexible Extension Interface
The board provides Two PCI-slot for graphics card, it also can support PCI-slot for LAN card
or other devices. The board also provides mini-PCI socket and ISA slot.

2.7 <Serial ATA installation>
P4ELA has six Serial ATA II interfaces with RAID function, the transfer rate of the SerialATA
II can be up to 300MB/s. Please go to http://www.serialata.org/ for more about Serial ATA
technology information. Based on Intel®ICH10DO, it supports Intel®Matrix Storage
Technology with combination of RAID 0,1,5 and 10. The main features of RAID on
ICH10DO are listed below:
1. Supports for up to RAID volumes on a single, two-hard drive RAID array.
2. Supports for two, two-hard drive RAID arrays on any of six Serial ATA ports.
3. Supports for Serial ATAATAPI devices.
4. Supports for RAID spares and automatic rebuild.
5. Supports on RAID arrays, including NCQ and native hot plug.
For more information please visit Intel’s official website.
For more about the system setup for Serial ATA, please check the chapter of SATA
configuration.
