Product Description
1.6.4.3 Intel^® Rapid Recover Technology (Intel^® RRT)
The board incorporates the Intel^® Rapid Recover Technology (Intel^® RRT). Intel®
Rapid Recover Technology is a feature of Intel® Matrix Storage Manager. It uses
RAID 1 (mirroring) functionality to copy data from a designated master drive to a
designated recovery drive. The master drive data can be copied to the recovery drive
either continuously or on request.
When using the continuous update policy, changes made to the data on the master
drive while the recovery drive is disconnected or offline are automatically copied to the
recovery drive when it is reconnected. When using the on request update policy, the
master drive data can be restored to a previous state by copying the data on the
recovery drive back to the master drive.
1.7 Real-Time Clock Subsystem
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.
NOTE
If the battery and AC power fail, custom defaults, if previously saved, will be loaded
into CMOS RAM at power-on.
When the voltage drops below a certain level, the BIOS Setup program settings stored
in CMOS RAM (for example, the date and time) might not be accurate. Replace the
battery with an equivalent one. Figure 1 on page 11 shows the location of the battery.
1.8 Legacy I/O Controller
The I/O controller provides the following features:
• Consumer Infrared (CIR) headers
• One serial port header
• Serial IRQ interface compatible with serialized IRQ support for PCI systems
• Intelligent power management, including a programmable wake-up event interface
• PCI power management support
The BIOS Setup program provides configuration options for the I/O controller.
