- Of course, about the same effect could be achieved by adding the line
- 1722/1440 3444 21 2 82 0 0x0C 0x00 0xCD 0x0C
- to /etc/fdprm and using setfdprm.

- If MAX_BUFFER_SECTORS in floppy.c would be increased to 21 (and head.S
- be changed accordingly), you might even get better performance than with
- interleave.
