Appendix B EDK II Sample Drivers
This appendix lists sample UEFI Drivers in the EDK II open source project along with their UEFI Driver related properties. This is not an exhaustive list of UEFI Drivers available from the EDK II open source project. Instead, a set of UEFI Drivers that provide examples of each major UEFI Driver feature this guide describes are listed. This appendix may be used to review UEFI Driver implementations that implement a specific UEFI Driver feature. Or it may be used to find an example UEFI Driver with a feature set that closely matches the features required for a new UEFI Driver so an existing driver can be cloned as a starting point.
