Board Installation
1-F. Fan Connectors (FAN1, FAN2)
Fan1
is for the CPU fan.
The
Fan2
connector is for the Chassis Fan.
1-G. CD Audio Connector (CD1)
1-H. Video-In (VIDEO1)
Video-in ATAPI Header for external multimedia
devices.
1-I. FSB jumpers (JP19, JP26)
If you have a
non-retail/engineering sample
CPU,
you can alter the front side bus setting by using these
jumpers in conjunction with each other.
1-J. Front Side USB Header (J2)*
Certain computer chassis allow for two front-end USB port connections. This board
provides a front side USB header should you decide to set up a USB connector at the
front side of your computer. Check with your chassis vendor for details.
1-K. EXTSMI Server Management Connector (JP1)
The EXTSMI (External System Management Interface) connector JP1 is used by some
plug-in cards. Certain applications associated with these plug-in cards use the interface
for hardware control and queries.
1-L. Power Management (JP18)
STR is part of the ACPI system, which provides energy saving functions for the
computer. If this jumper is set to NOT ENABLED (close pins 2-3) which is the
default setting, the system will default to S1 state, even if the BIOS has ACPI
functions enabled. If the jumper is ENABLED (close pins 1-2), and ACPI functions
are enabled in the BIOS, the system will go to energy saving S3 state (hibernation),
saving the system’s state into volatile memory.
1-M. Sleep Button (JP24)
The sleep button jumper is connected to the front panel sleep button (if one exists).
The purpose of this jumper is to provide for manual activation of the BIOS power-
saving state.
