P4LA User’s Manual Introduction
Chapter1 <Introduction>
1.1 <Product Overview>
P4LA is the motherboard with last Intel desktop technology with industrial motherboard
form factor. Based on Intel® 945G and ICH7R, the board integrates a new Pentium 4
processor 775-pin socket, DDR2 memory slot, Intel® Graphic Media Accelerator 950
technology, PCI express interface and Serial ATA II with RAID function for a powerful
desktop system.
Intel® LGA775 processor
The Intel® Pentium 4 processor now comes with a new form factor with 775-pin PLGA
package, for 533/800/1066MHz front-side-bus, 2MB L2 cache, and for 90nm manufacturing
technology, the PLGA processor without pin header on solder side can make user installing
the processor on the socket easier.
Intel® 945G and ICH7R chipset
The Intel 945G integrates DDR2 400/533/667MHz for memory, and Graphic Media
Accelerator (GMA) 950 technology for new graphic engine. It can provide up to 224MB of
frame buffer when you install over 256MB of system memory. The ICH7R integrates with up
to 8 USB2.0 interfaces (8 ports for P4LA), and serial ATA II interface with RAID function.
One Marvell E8053
One Gigabit LAN with Marvell E8053, P4LA comes with a powerful network function for the
system that requires large transfer data of NAS system or Server platform.
PCI-Express interface
P4LA integrates one x16, x4 and x1 PCI-Express interface, it can provide up to 8GB/s of
bandwidth, which AGP 8x can only provide up to 2GB/s.
Multimedia interfaces
P4LA also integrates 7.1 channel HD audio, PCI-Express, PCI and ISA interface, for these
flexible function, system integrator can built more powerful systems for many applications.

For Windows 98/SE/ME, Windows NT4.0 and DOS system, they only support up to 4 IDE
devices including SATA devices, and Windows 2000/XP/Server2003 have no such
limitation.

P4LA User’s Manual System 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.
Once you enable the RAID mode, the boot-up screen would pop up the RAID configuration
option for setup.
SATA Configuration 36
P4LA User’s Manual System Configuration
On-Chip Serial ATA mode:
This option can let you select operation modes of Serial ATA drives.
Disabled: To disable the onboard Serial ATA controller.
Auto: To allow the system select the optimized mode automatically.
Combined mode: PATA and SATA work as two channels for supporting two drives on each
channel.
Enhanced mode: Max supported of the PATA and SATA for up to 6 drives.
SATA Only: To disable the PATA and only apply the SATA drives.
Notice: The Combined mode and Enhanced mode are supported depends on your
operating system, please check page35 for relative information.

3.2 <SATA RAID Configuration>
The board integrates Intel® ICH7R 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.

3.4 <Video Memory Setup>
Based on Intel® 945G chipset with GMA (Graphic Media Accelerator) 950, the board
supports Intel® DVMT (Dynamic Video Memory Technology) 3.0, which would allow the
video memory be triggered up to 224MB.
To support DVMT, you need to install the Intel GMA 950 Driver with supported OS.
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 224MB.
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 appl ication, this item is
strongly recommend to be selected as MAX DVMT.
