  If you have correctly installed DRIVER.SYS and formatted with the
correct options on DOS format you will be able to generate a 720k floppy
on an AT (1.2MB) type drive. Since various vendors hack their drivers
and format commands I can't give you the correct incantation for YOUR
machine.

  I have seen DOS gurus do this on Dell MS-DOS and PC-DOS with vendor
supplied software, and have been able to read the disks as 720k on
Xenix. Is the 3B2 format the same? The DOS stuff produces 80 tracks, 9
sectors of 512 bytes.
