<P>The Atari supports disk drives with either 128 or 256 byte sectors.
|
|
The first three sectors of any disk are always 128 bytes long though. This is
|
|
because the system can only boot from 128 bytes sectors.</P>
|
|
<P>Therefore the DIO read and write functions transfer only 128 bytes
|
|
for sectors 1 to 3, regardless of the type of diskette.</P>
