PCI Express™ interface

The motherboard fully supports PCI Express, the latest I/O interconnect
technology that speeds up the PCI bus. PCI Express features point-to-point
serial interconnections between devices and allows higher clockspeeds by
carrying data in packets. This high speed interface is software compatible with
existing PCI or PCI-X specifications. See page 2-18 for details.

Gigabit LAN solution

The motherboard comes with onboard dual Gigabit LAN controllers to
provide a total solution for your networking needs. The onboard Broadcom
BCM5721 controllers use the PCI Express interface with a network
throughput close to Gigabit bandwidth. See pages 2-21, 2-22, and 2-25
for details.

Dual RAID solution

The Intel

ICH6R allows RAID 0 and RAID 1 configuration for four Serial ATA

connectors. See page 2-28 for details.

The optional Adaptec AIC-7901 PCI-X U320 SCSI controller (for P5CR-LS
model only) allows RAID 0, RAID 1, and RAID 0+1 configuration for Ultra
320 SCSI connectors. See page 2-29 for details.

Zero-Channel RAID (ZCR) solution

(optional for P5CR-LS model only)

The optional Adaptec AIC-7901 PCI-X U320 SCSI controller also supports
an optional Zero-Channel RAID card on the 64-bit PCI-X slot to create a
RAID solution, including RAID 0 (striping), RAID 1 (mirroring), RAID 0+1,
and RAID 5. The ZCR capability provides a cost-effective high-performance
and added reliability.

USB 2.0 technology

The motherboard implements the Universal Serial Bus (USB) 2.0
specification, dramatically increasing the connection speed from the
12 Mbps bandwidth on USB 1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is
backward compatible with USB 1.1. See pages 2-25 and 2-31 for details.
