5EAS ONE SHEET MANUAL

This leaflet is meant to help you set the jumpers for your 5EAS Mainboard in order to boot the Mainboard. A manual that describes the possibilities of your board in more detail is included on the CD ROM that came with your 5EAS board. Please refer to Diagram 1 for the location of the relevant jumpers:
