Administrators Hervé Posted June 6, 2021 Administrators Share Posted June 6, 2021 Assuming the E5420 specs will be similar or very close to the E6x20 models, you can lookup existing guides for those and build from there. Use Clover, it'll be easier. Link to comment Share on other sites More sharing options...
