Changing Tyan Default Video Output Source

Document Scope

This document provides instructions for adjusting the BIOS settings on a Tyan system to switch the default active video device from the onboard graphics to an off-board graphics card. This process ensures seamless utilization of the preferred graphics hardware configuration for optimal visual output.

Introduction

This setting applies to the following Tyan barebones chassis:
