If you used the rom_grabber and oldworld booting, then it should be
possible boot MacOS 9.1. However, oldworld booting on 8.6 and later
*NOT* recommended (it might be more unstable, and the pram might not
be saved/restored properly). Moreover, only certain boot ROMs are
MOL compatible (ROMs from 7200, 8500 and a few others).
Oldworld booting is intended to used on MacOS 7.5.2 - 8.5.

Mixing old "Mac OS ROM" files with newer systems is *not*
recommended, although there are a few exceptions (The 3.8 ROM
work well on all MacOS 9 installations I've seen for instance).

This is the recommended method. Since I'm currently working with
a revised user guide... MacOS did not install a "Mac OS ROM" file
in the System Folder by default, right?
