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?
G'luck,
Peter
