How to use a laptop as the keyboard and screen for a headless server

This instruction explains how to use a laptop as the keyboard and screen for a headless a server using the KVM2USB solution. When you connect this frame grabber to any computerized machine with a VGA output and a laptop, it emulates keyboard, mouse and monitor allowing you to perform administering quickly and easily. KVM2USB transfers the image from the host machine to the laptop and simulates the keyboard and mouse outputs of the laptop.

KVM2USBcan be used for multiple operations on the headless server such as selecting a different operating system, interrupting boot up, running the server in different operation modes (if it is supported by the server) and configuring the headless server BIOS settings. In our example the laptop is running Windows.
