1-L. Frontside USB Header (J38)
Certain computer chassis allow for a front-end USB port connection. There-
fore, this board provides a front side USB header should you decide to set up
a USB connector at the front side of your computer. Note: If you use J38, you

will be unable to use the TOP USB port at the back of the motherboard. Both
J38 and USB1 share the same channel.

1-M. Boot Block Jumper (JP3)
Locked Unlocked
JP3
OFF
ON
By default, this jumper is set to the OFF (locked)
position. Having the Boot Block protection "locked"
will allow system-bootup even if the BIOS bootup fails.
In other words, the boot block acts as a backup in case
your BIOS fails to boot the system. If the jumper is set
to the ON position, this would allow the Boot Block to
refresh its BIOS code at the same time you flash a new
BIOS. Note: If the Boot Block is 'unlocked' (jumper
ON) and if failure occurs during a new BIOS Flash,
you run the risk of rendering your entire system un-
bootable. The "backup" protection of the Boot Block
JP3, J38
will be lost.
Soft Power Connector
The Soft Power Connector is part of jumper block J9 (pins 6-8). The Tomcat
i810 uses the chipset for power management, including turning on and off the
system. If the Power Button Function option in the BIOS Power Management
Menu is set to On/Off (which is the default), pressing the power button once
after the BIOS has booted up will turn the system on and off. If the Power
Button Function option is set to Suspend, pressing the power button once will
wake the system or send it to Suspend mode. In this case, you cannot turn the
system off unless you shut down through the Windows operating system or
you hold the power button down for four seconds.
Hardware Reset Switch Connector Installation
The Reset switch on your case's display panel provides you with the Hard-
ware Reset function, which is the same as power on/off. The system will do a
cold start after the Reset button is pushed.
