POWERING ON PEGASUS
Follow these steps to power on and verify the functionality of the Pegasus SBC. This process assumes
you have a Pegasus SBC and cable kit.
1. Connect a VGA monitor to the SBC. Attach the VGA cable, 6981084, to the VGA connector on the
SBC and connect your monitor VGA cable to the DB9 socket.
2. Connect a keyboard and mouse to the SBC. Attach the PS/2 Keyboard/Mouse cable, 6981162, to
the PS/2 connector on the SBC and connect your keyboard and mouse devices to the connectors
on the other end of the cable.
3. (Optional for USB Keyboard/Mouse) If you are using a USB keyboard and mouse, attach the USB
cable, 6981171, to the USB0‐1 connector on the SBC and connect your keyboard and mouse
devices to the connectors on the other end of the cable.
4. Connect an external IDE hard drive or CD device to the SBC. Attach the IDE ribbon cable,
6981004, to the IDE/Flashdisk connector on the SBC and connect your IDE device to the
connector on the other end of the cable. Note: you must provide an external source of power
for your IDE device.
5. (Optional for USB storage device) If you are using a USB storage device, attach the USB cable,
6981171, to the USB0‐1 (USB2‐3 if using a USB keyboard and mouse) connector on the SBC and
connect your external storage device to the USB0 (USB2 if using a USB keyboard and mouse)
connector on the other end of the cable.
6. Connect the SBC to power. Attach the Power In cable, 6981175, to the Power In connector on
the SBC. Ensure your +5V power source is off. Connect your +5V power source to the other end
of the cable.
7. Turn on the power source.
The Pegasus BIOS screen should appear and then the SBC should begin booting from the external
storage device.
BIOS CONFIGURATION FOR ADD‐ON BOARDS
When you plug PC/104 boards onto Pegasus, the BIOS may or may not recognize the new board. If the
new board is not recognized, you may need to configure the new hardware in the BIOS before being
able to use it. You can configure the system’s IRQ/DMA resources from the BIOS’s PnP/PCI
Configurations screen. Following is a table of the IRQs for the system peripheral devices.
