* This is the low-level hd interrupt support. It traverses the

* all the functions are called within interrupts, we may not
* sleep. Special care is recommended.

* modified by Drew Eckhardt to check nr of hd's from the CMOS.
*
* Thanks to Branko Lankester, lankeste@fwi.uva.nl, who found a bug
* Bugfix: max_sectors must be <= 255 or the wheels tend to come
* off in a hurry once you queue things up - Paul G. 02/2001
