This driver seems to work very very well in no hault mode. I notice the only 
time floppy access slows the whole system is during the 1st part of a 
format.

To test I started a backup, switched to another screen and started loading / 
playing rogue from my hard disk. Hardly noticed the floppy drives were 
running.
