[net.micro.mac] Duplicate Resources in System File

mazur@endor.harvard.edu (Eric Mazur) (07/29/86)

This is something that has come up before, but I would like to have more
info.

The new ROMs contain several resources that used to be (and *still* are) in
the System file. In this month's MacUser the 'MacTeam' answers a question
from a reader who wonders what resources he can remove from the System file.
According to the article the resources that are both in ROM and in the System
file are:
			DRVR	2, 3, 4, 9, and A
			SERD	0
			MDEF	0
			WDEF	0
			PACK	4, 5, and 7
			CURS	1, 2, 3, and 4
			FONT	Chicago

The article does not guarantee that this list is complete, but "it's more
accurate then Technical Note #57". [This note is missing from my set, so I
could not check].

But then comes a sentence that makes me worry: "Theoretically you could remove
these, but Technical Support doesn't recommend doing so. There may well be
some applications that expect to find these as RAM-based resources." [What
good is it then to have them in ROM?!]. 

Has anyone removed these resources? Did you encounter any problems? 

I have a related question concerning PACK 0. David Dunham (how can I reach
him from Usenet?) told me my problems with MiniWriter were due to the
presence of the PACK 0 resource in the System file. So I removed it, but
I got a whole series of new problems. Printing didn't work, the system
bombed now and then. I ended up putting it back and most of the problems
went away. What is PACK 0 for? I tried finding a reference in Inside Mac,
but couldn't find any. Throw it out too, or leave it?
