Was working for Intel in 1985 and bought their system 310 (x286) with 512K of

Xenix was offered and came on 21 5.25 inch floppies.

A very good discussion including the 2M and 2MGUI driver.The author,
Ciriaco García de Celis sent me the 2M program sometime around 1994.
It's interesting, and uses 82 cylinders on a DSHD drive and can come

There was also a 2MGUI (having nothing to do with graphics) version
IBM XDF has multiple sizes of sectors on each track!
Similarly, the Ensonic Mirage got 880K on a "720K" disk by using five 1024
byte sectors plus a 512 byte one.

almost RAW write of a track.
