To quote luigi's commit message, introducing this functionality to -stable's PicoBSD.. luigi 2000/12/21 18:11:14 PST Modified files: (Branch: RELENG_4) release/picobsd/build build Log: Add support for different floppy sizes (1480, 1720, 2880). The "1720" format will not boot most likely. The "1480" format (really 1476KB, 18 sectors x 82 tracks) does boot fine on the systems i have tried. Can you try 1480?
