Apple //e how to load from Drive 2
So I just got an amazing apple //e setup (For a rock bottom price of $125!) And everything works, but I would like to take advantage of the duo disk drive. I would like to leave the boot disk in drive one, and put other stuff in drive to. But I can't figure out how to exactly "load" from drive 2. Simply googling hasn't helped much here. So I came here. Thanks in advance.
Apple //e-OTHER, Duo Disk Drive, Rev B?
