Real-Time Clock, Cmos Sram, And Battery - Intel BLKD865PERL Technical Product Specification

IDE I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI resource
steering is used. Native mode is the preferred mode for configurations using the Windows XP and
Windows 2000 operating systems.

1.7.3.3 Intel RAID Technology
Boards equipped with the ICH5-R support RAID (Redundant Array of Independent Drives) level 0
on the Serial ATA ports. RAID 0 provides the ability to support striping. Two physical drives, of
identical size, can be teamed together to create one logical drive. As data is written or retrieved
from the logical drive, both drives operate in parallel, thus increasing the throughput.
✏
NOTE
The ICH5-R provides support for RAID 0 and RAID boot in Windows XP only.
1.7.3.4 RAID Boot Configuration Overview
A RAID array can be created by using the existing Serial ATA Ports, correctly configuring the
BIOS, and installing drivers. The following steps are required to successfully establish a RAID
configuration.
1. Enable RAID Support in BIOS.
2. Create a RAID array using the Intel
3. Install the IAA 3.0 RAID driver.
4. Format the RAID array.
5. Install the IAA 3.0 Companion Utility (this step is optional).

1.7.4 Real-Time Clock, CMOS SRAM, and Battery

A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer
is not plugged into a wall socket, the battery has an estimated life of three years. When the
computer is plugged in, the standby current from the power supply extends the life of the battery.
The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied.
