X9DRT-HF/HIBQF/HIBFF Motherboard User’s Manual
1-7 Super I/O
The X9DRT-HF/HIBQF/HIBFF motherboard supports two 16550-compatible serial
communication connections. COM Port 1, located on the rear IO backplane, can
be used for input/output. The other supports SOL only. Both UARTs provide legacy
speed with baud rate of up to 115.2 Kbps as well as an advanced speed with baud
rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Conguration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through an SMI or SCI function pin. It also features auto power management
to reduce power consumption.
1-8 Advanced Power Management
The following new advanced power management features are supported by the
motherboard.
Intel
®
Intelligent Power Node Manager (NM) (Available
when the NMView software is installed)
The Intel
®
Intelligent Power Node Manager (IPNM) provides your system with
real-time thermal control and power management for maximum energy efciency.
Although IPNM Specication Version 1.5/2.0 is supported by the BMC (Baseboard
Management Controller), your system must also have IPNM-compatible Manage-
ment Engine (ME) rmware installed to use this feature.
Note: Support for IPNM Specication Version 1.5 or Version 2.0 depends
on the power supply used in the system.
Management Engine (ME)
The Management Engine, which is an ARC controller embedded in the IOH (I/O
Hub), provides Server Platform Services (SPS) to your system. The services
provided by SPS are different from those provided by the ME on client platforms.
1-9 Overview of the Nuvoton WPCM450 Controller
The Nuvoton WPCM450R Controller, a Baseboard Management Controller
(BMC), supports 2D/VGA-compatible Graphic Cores with PCI interface, creating
multi-media virtualization via Keyboard/Video/Mouse Redirection (KVMR). The
WPCM450R Controller is ideal for remote system management.
