1.3 Special features
1.3.1 Product highlights
Latest processor technology
The P4B266-E motherboard supports the latest Intel Pentium 4 478/
Northwood Processor, also known as P4, via a 478-pin surface mount ZIF
socket. The Pentium 4 processor utilizes the advanced 0.18 micron
processor core in FC-PGA2 package for a 2.0GHz frequency, while the
Northwood processor uses the 0.13 micron processor core with 512KB L2
cache for up to a speedy 2.4+GHz frequency. The P4 offers optimized
performance for audio, video, and Internet applications. See page 2-4.
DDR memory support
Employing the Double Data Rate (DDR) memory technology, the P4B266-
E motherboard supports up to 2GB of system memory using PC2100/1600
DDR DIMMs. The ultra-fast 266MHz memory bus doubles the speed of the
PC133 SDRAM to deliver the required bandwidth for the latest 3D
graphics, multimedia, and Internet applications. See page 2-10.
RAID 0/RAID 1 support (optional)
The motherboard includes the Promise ® chip PDC20276 and two ATAIDE
interfaces to support Redundant Array of Independent Disks (RAID)
configuration. This feature supports Ultra ATA/133 drives, and is backward
compatible with Ultra ATA/100/66/33 drives. The RAID controller onboard
supports RAID 0 and RAID 1 configurations.
RAID 0 (called data striping) optimizes two identical hard disk drives to
read and write data in parallel, interleaved stacks. Two hard disks perform
the same work as a single drive but at a sustained data transfer rate,
double that of a single disk alone, thus improving data access and
storage. RAID 1 (called
data mirroring) copies and maintains an identical
image of data from one drive to a second drive. If one drive fails, the disk
array management software directs all applications to the surviving drive
as it contains a complete copy of the data in the other drive. This RAID
configuration provides data protection and increases fault tolerance to the
entire system. Refer to section “5.4 RAID 0/RAID 1 configurations” on
page 5-18 for more information.
