Do not use Quickstart. Run Workbench 3.X, press F12, go to Floppies, insert your ADF into DF0, set speed to Turbo and click on Reset. Then run Octamed and load your mod files from DH2.
What rkauer meant is the checkbox "add pc drives at startup" which is on the Hard Drives page. But AFAIK Amiga Forever has this checked by default.
