There are three solutions:
1. Write your own diskroutines directly accessing the FDC, which leave the
interrupts enabled. However, you will need to write a good CRC error check
routine in case you miss some bytes (music can take up a lot of time).
However, although it is possible: FORGET IT!!! Aargh, to be precise. Awful
solution. The ones below are much better.
2. Play a NOP - Unknow Reality-alike kind of sound, or play looped samples
on the Music Module / MoonSound. Those will keep playing while accessing
disk too.
3. When loading from harddisk in very small blocks it should be possible to
catch every interrupt. So make playing music while loading a harddisk-only
feature.
