MI-220
Serial ATA
The MI-220 provides three SATA ports with data transfer rates of
up to 6.0 GB/s on 2 ports and up to 3.0 GB/s on 1 port. Intel®
Rapid Storage Technology supports AHCI and RAID 0/1/5/10
functionality.
USB 2.0
The MI-220 provides 6 USB 2.0 ports supporting transfer rates up
to 480 Mb/s. All ports are USB 1.1 compatible.
Hardware Monitoring
A built-in, proactive hardware monitoring system in the Super I/O
monitors the CPU temperature, system fan speed, and voltage
levels to prevent overheating and/or component damage, effect
timely failure detection, and ensure stable supply of current for
critical components.
Watchdog Timer
The watchdog timer (WDT) monitors system operations based on
user-defined settings. The WDT can be programmed for different
time-out periods, such as from 1 to 255 seconds or from 1 to 255
minutes. The WDT generates a reset signal, then a reset request,
after failure to strobe it within the programmed time period. A reg-
ister bit may be enabled to indicate if the watchdog timer caused
the reset event. The WDT register is cleared during the power-on
sequence to enable the operating system to take appropriate
action when the watchdog generates a reboot.
