/*

 * Thanks to James van Artsdalen for a better timing-fix than
11 
 * the two short jumps: using outb's to a nonexistent port seems
12 
 * to guarantee better timings even on fast machines.
13 
 *
14 
 * On the other hand, I'd like to be sure of a non-existent port:
15 
 * I feel a bit unsafe about using 0x80 (should be safe, though)
