1.4 Configuration
The majority of the configuration of the motherboard is done through the Setup utility built into the
BIOS – discussed later in this document. There are, however, a number of jumpers that control the
operation of the motherboard as described below. Some jumpers are not fitted to certain products.
Figure 3. Jumpers
1.4.1 Operation Mode Selection Jumper (JP3)
This jumper selects one of the following operating modes for the motherboard (pins 1, 3, 5) and
controls write capability for the CPLD content (pins 2, 4, 6).
Normal Mode (Jumper between pins 1 & 3) This is the factory default position the jumper
should be in for normal operation of the motherboard.
Configure Mode (Jumper between pins 3 & 5) With the jumper in this position the motherboard
automatically runs the BIOS Setup utility regardless of the state of the Setup
disable flag that can be set in the BIOS defaults. In this mode, the CMOS RAM
contents are ignored and the defaults are used to configure the motherboard.
