[comp.sys.mac] Do CDEVs work without Control Panel installed?

ajq@mace.cc.purdue.edu (John O'Malley) (11/01/88)

OK, here's a simple question.  Do CDEVs like Vaccine work when they are
installed on a hard disk that has no Control Panel installed?

Since Vaccine's icon shows up at boot time, I assume that it's running.  But
with no Control Panel present I can't double check.  I'd rather not install
it, either, 'cause it's just another thing for our Mac lab users to fool
around with and cause me headaches!

99.99% chance that such cdev's will work without the Control Panel,
provided they have INIT resources in them. You just won't be able to
configure them. If you are short of space, you could probably
delete the cdev, mach, nrct resources also, but be careful. This will
make it smaller, but the control panel will not be able to access it forever.

  Here's the simple answer: yes. Vaccine (and many others) are actually
INITs, with a 'cdev' interface for setting parameters. Once you've set
the parameters the way you want them, you can blow away the Control
Panel DA and they will continue to load at boot time in the normal way.

Yes, CDEVs do work without the control panel.  I have a setup on our
public hard disks (for laser printing) with Vaccine, Moire, (and GuardDog
for a while).  All of them work fine and are protected from prying
users, malicious or otherwise.

At school I have installed on several Macs Quickeys and (in system 4.2) made
it invisible and removed the control pannel after I configured Quickeys.  This
allowed me to then make all of the applications on the hard drives invisible.
This was a great boon since what you can't see you can't delete or copy and
all that good such (unless you know how, and that is not the case at this
stage in the game, it is a closely guarded secret.  In fact, to my knowledge
the files are still on one drive and I am the only one who knows about them...)
and all we do is have a command-shift list next to the computer saying that if
you want to use MacWrite hit this and if you want to use that hit this sequence
and it all works quite well.  So I can say truthfully that Quickeys and General
and Mouse and Keyboard will all work without the Control Pannel being
installed.  Hope this helps answer your question.

	Just a reminder that this trick will not work work with System 6.0.x as
Apple has decided that it's System should do 'virus protection' of it's own.
What this boils down to is that any Init/cdev/rdev, etc. in the System Folder
which is invisable will NOT be recognized by the INIT31 (Init Loader) mechinism
and so will not be loaded.  

Just wanted to point this out before people started trying it with System 6.0.x
and wondered why it didn't work!!

Yes, I know that, that is why I stated that it was on System 4.2 so you would
know that I knew what I was talking about.  In System 6.0.2 enviroments I hide
the icons behind other icons.
