1.7.1.1 SATA RAID
The board supports Intel Rapid Storage Technology which provides the following RAID
(Redundant Array of Independent Drives) levels via the Intel P67 Express Chipset:
• RAID 0 - data striping
• RAID 1 - data mirroring
• RAID 0+1 (or RAID 10) - data striping and mirroring
• RAID 5 - distributed parity
NOTE
In order to use supported RAID features, you must first enable RAID in the BIOS.
Also, during Microsoft Windows XP installation, you must press F6 to install the RAID
drivers. See your Microsoft Windows XP documentation for more information about
installing drivers during installation. Both Microsoft Windows Vista and Microsoft
Windows 7 include the necessary RAID drivers for both AHCI and RAID without the
need to install separate RAID drivers using the F6 switch in the operating system
installation process.
1.8 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 via the power supply 5V STBY rail.
NOTE
If the battery and AC power fail, date and time values will be reset and the user will be
notified during the POST.
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 13 shows the location of the battery.
1.9 Legacy I/O Controller
The I/O controller provides the following features:
• Consumer Infrared (CIR) headers
• 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.
