Hi Laurent,

"The DE bit allows the Pentium+ to set breakpoints in I/O space using
the breakpoint registers. The R/W coding 10b is used to indicate that
the breakpoint is in I/O space on the Pentium+.  The 10b encoding was
marked as 'invalid' for pre-Pentium CPUs."

hmmm, breakpoints handling may be somewhat hairy to handle.
I withdraw my previous statement about implementing DE-bit fully.

Perhaps forcing DE bit to 1 would be okay, as long as
no kernel debugger in Hazelnut (or pistachio) needs it.

So your hack may be the best work-around for now ;-)

Regards,
