The Mac stores all of those parameters in Non-volatile RAM.  They are read
in at boot and are written out when changed.  A friend of mine who has a
Mac had his NVRAM go bad, so he wrote an INIT that reads them in from
the system folder and writes them out when they get changed.  I never sent
it out because it did not work with sys2.0/finder4.1 on the Sac (worked 
fine on the Mac).  But now that Spectre is out and most Sac-ers are using
4.0/5.3 anyway, I probably should send it out.  Its incredibly small, but
I don't know how to post Mac prgs to the net (and I don't currently have
access to the net from home).  Reply to me if you need it badly, otherwise
look for it on Genie, my BBS, or fnet (the FoReM network) soon.
