ACPI
The motherboard supports the Advanced Configuration and Power Interface (ACPI) as
defined by the ACPI 2.0 specifications. An ACPI aware operating system can put the
system into a state where the hard drives spin down, the system fans stop, and all
processing is halted. However, the power supply will still be on and the processors will
still be dissipating some power, so the power supply fans will still run.
The system board supports sleep states s0, s1, s3, s4, and s5:
■
s0: Normal running state.
■
s1: Processor sleep state. No context will be lost in this state and the processor
caches will maintain coherency.
■
s3: Suspend to RAM. Your working environment is Saved To RAM.
■
s4: Hibernate. Your working environment is Saved To Disk
■
s5: Shutdown.
Keyboard and Mouse
The keyboard/mouse controller is PS/2-compatible.
Peripheral Bays
Your system features three 5.25-inch bays that you can use with either a hard disk
drive, an optical device or a tape backup unit.
The 3.5-inch bay may be fitted with an optional floppy disk drive.
RAID Support
Depending on your system, the motherboard features an onboard controller (ESB2-E)
which provides RAID support either for S-ATA and/or SAS configurations.
SATA On-board controller (depending on your system)
■
Supports both 1.5 and 3.0 Gbps data transfer rates.
■
Can be set-up via the BIOS Setup utility.
The BIOS Setup utility provides multiple drive configuration options on the
Advanced > ATA Controller setup page, some of which affect the ability to
configure RAID. The “Onboard SATA Controller” option is enabled by default.
When this option is enabled, the “SATA Mode” option can be set to either Legacy
or Enhanced. The Legacy and Enhanced modes affect the RAID configuration as
follows:
- Legacy supports four disk drives and does not provide RAID support.
- Enhanced supports six disk drives and is required for RAID configurations.
