8 Introduction
Gigabit Ethernet
The M-322 uses two Realtek RTL8111C Gigabit Ethernet control-
lers connected to the PCI-E x1 bus of the ICH9DO. Operation at
data rates of 10/100/1000 Mbps, Wake on LAN are supported.
Serial ATA
Storage is efficient and secure with the Serial ATA interface. Utiliz-
ing the Intel® ICH9DO, the M-322 supports up to six Serial ATA
devices capable of reading/writing data at up to 3 Gbps. Intel®
Matrix Storage Technology provides support for RAID 0/1/5/10.
Hardware Monitoring
A built-in, proactive hardware monitoring system monitors the
CPU temperature, system fan rotations, and voltage levels to pre-
vent overheating and/or component damage, effect timely failure
detection, and ensure stable supply of current for critical compo-
nents.
Watchdog Timer
The watchdog timer (WDT) monitors system operations based on
user-defined configurations. The WDT can be programmed for dif-
ferent 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 register 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.
Trusted Platform Module
The M-322 supports TPM ver. 1.2 (Trusted Platform Module) for
secure storage of keys, passwords and digital certificates. Sys-
tems supporting TPM offer improved hardware-based security in
numerous applications, such as file and folder encryption, local
password management, S-MIME e-mail, VPN and PKI authentica-
tion and wireless authentication for 802.1x and LEAP.
