Keep talking 8-) It's not only my hard disk driver that intercepts
Trap #1 before POOLFIX shows up. There are other hard disk drivers,
and there are also some ROM port or ACSI based network drivers that
have similar problems. Future versions of my hard disk driver will
have a switch telling it to leave Trap #1 alone to avoid such problems.
A network driver, however, must occupy Trap #1 to implement network
services - there's no choice. So that's why I tried to improve
POOLFIX.

When talking about my version of POOLFIX, please refer to it as
PFIX_CB, _not_ POOLFIX4. And please don't bother Atari if there's
trouble with my POOLFIX version - it's all my own silly fault.
