Getting Started
10. Install the video adapter:
Insert the PCI video adapter into one of the available PCI slots. Connect the monitor cable to
the VGA port on the card.
11. Connect the power supply:
Connect the WTX power supply provided with the evaluation kit.
Note: Some WTX power supplies do not have an on/off switch. In this case, ensure that the
power supply is unplugged from the wall prior to plugging in the WTX power
connectors.
Connect the power supply cables to the power headers as indicated below:
•
Install the P1 connector of the power supply into ‘WTX Main Pwr’, connector J3M1 on the
board.
•
Install the P2 connector of the power supply into the ‘Aux Power Supply’, connector J3P1 on
the board.
•
Install the P3 connector of the power supply into the ‘WTX DIG 12V’, connector J1T4 on the
board.
12. Power up the board: Turn on the power to the monitor and evaluation board. When the power
is on you should see two power-indicator LEDs light up (located next to reset switch, see
Figure 2-1). Ensure that the fansinks on both the processors are operating.
•
Power Switch: The red push-button switch labeled S11R1 is the power switch to the
baseboard. Push it once to turn the power on or off.
Please note that when the system is powered down using the S11R1 switch, the standby
voltages are still present on the board. Power can be completely removed from the board only
by removing AC power from the WTX power supply or by removing the WTX power supply
connector from the baseboard.
•
Reset Switch: The black push-button switch labeled S11P1 is the reset switch. When pushed
once, this switch will provide a hard reset to the baseboard.
Note: S11R1 is the power switch that should be used to turn the system on and off. Please note that this
switch may be in the on position when you first apply power through the WTX power supply.
2.6 Configuring the BIOS
General Software’s BIOS is pre-loaded on the evaluation board. You will need to make changes to
the BIOS to enable hard disks, floppy disks and other supported features. You can use the Setup
program to modify BIOS settings and control the special features of the system. Setup options are
configured through a menu-driven user interface. Chapter 5, “BIOS Quick Reference” contains a
description of BIOS options. BIOS updates may periodically be posted to Intel’s Developers’ web
site at:
