Introduction
USB Ports
The system board supports USB 2.0 and USB 1.1 ports. USB 1.1
supports 12Mb/second bandwidth while USB 2.0 supports 480Mb/
second bandwidth providing a marked improvement in device
transfer speeds between your computer and a wide range of
simultaneously accessible external Plug and Play peripherals.
Dual Function Power Button
Depending on the setting in the "Soft-Off By PBTN" field of the
Power Management Setup, this switch will allow the system to enter
the Soft-Off or Suspend mode.
Wake-On-Ring
This feature allows the system that is in the Suspend mode or Soft
Power Off mode to wake-up/power-on to respond to calls coming
from an external modem or respond to calls from a modem PCI
card that uses the PCI PME (Power Management Event) signal to
remotely wake up the PC.
Wake-On-LAN
This feature allows the network to remotely wake up a Soft Power
Down (Soft-Off) PC. It is supported via the onboard LAN port or
via a PCI LAN card that uses the PCI PME (Power Management
Event) signal. However, if your system is in the Suspend mode, you
can power-on the system only through an IRQ or DMA interrupt.
