Btw, things like this:

	+#define IDEFLOPPY_TICKS_DELAY  HZ/20   /* default delay for ZIP 100 (50ms) */

are just bugs waiting to happen.

Hint: see what happens when you do something like this:

	high_byte = IDEFLOPPY_TICKS_DELAY >> 8;
	low_byte = (unsigned char) IDEFLOPPY_TICKS_DELAY;

and watch in amazement how you get entirely the wrong value if HZ is 1000.

Try it out..
