I just learned that the Micronics 386/33 reserves the 384K chunk whether
you tell it to use shadowing or not. I am running 386 Xenix 2.3 and I would
like to know if there is any performance to be gained by using this memory
for BIOS shadowing under a protected OS, or does Xenix duplicate the BIOS
functionality some other way? 

Thanks for any tips, suggestions, or meaningful explanations,
