- Okay, the following was captured locally from a message with the header:

- From: rrr@duck.svl.cdc.com (Rich Ragan)
- Subject: Building a Sys7 Emergency Disk
- Date: Mon, 10 Feb 92 14:12:54 PST
- The following description should probably go into the archives
- rather than just be a one time posting.
- Thanks, Rich Ragan (rrr@svl.cdc.com)

- I'm not sure where it came from originally, but now that I have attributed my
- source, here is an excerpt which might help you out:
-
- [do the following to a system installed under choice "minimum configuration"
- by installer, such as the one on Disk Tools, and the idea is that this is an
- emergency system only, with a disk recovery utility on it, and not even the
- finder.]
-
- 8) Now you are ready to put the Minimal System file on the floppy onto
- a "quick weight loss diet". You will need ResEdit to do this. Start
- up ResEdit and delete the following resources types/numbers from
- the Minimal System file. If you don't know how to use ResEdit, find
- someone who does (i.e., kids don't try this without adult supervision).
-
- The essence of the shrinking procedure is that there is a lot of good
- stuff in the System that is not needed when more pressing things are
- going on (like recovering a crashed hard disk). Therefore, you will
- delete these nice but superfluous parts of the Minimal System file.
- The following list of resource type and numbers appear to be safely
- deletable for a minimum system. Don't try to construct a system you
- run everyday this way. For example, transcendantal functions are
- deleted (hopefully no disk recovery packages needed to compute sines).
- Ranges of resources to delete are separated by a colon.
-
- Major space gains come from deleting the AppleTalk DRVR's and the
- packages (PACK 5, and 9-15). For example, PACK 14 is the Balloon
- Help stuff. Each PACK owns other resources which can be removed
- after the PACK is gone. The owner of a resource can be seen by
- selecting the resource and doing a get resource info. Thus if you
- have deleted PACK 14 you can safely delete all resources it owns
- (like hdlg, hmnu, DITL, DLOG, etc.). Of course you must not try to
- use balloon help after that. Rather than make you think about it
- here is a list of things you can delete to build a minimum system.
- You may not have all the things that are in the list depending on
- which machine you built the minimum system for.

- DITL & -32512:-32509 -16492:-16491 -16483: -16482

- ics# all but 16386 (Apple Icon)
- ics4 all

- ics8 all
- PACK 9:15 and 5 (if present)
- PICT -16482:-16485 -5790 -5789 -5760
- -5696:-5694

- -5856 -5792:--5787 -5759 -5696
- -4096
-
- 9) After quitting from Resedit and saving the changes you
- should have a floppy with a lot of space on it. Now put
- your Disk Recovery utility on this disk as well. Rename
- the Disk Recovery Utility to have the name Finder. It will
- now be run immediately when you boot from this floppy since
- it is thought to be the normal Finder.
- [end quote]
- not sure if that has anything to do with what you were wondering, but hope it
- helped someone.
