[comp.sys.atari.st] Crash when switching resolutions

cr1@beach.cis.ufl.edu (Anubis) (03/26/90)

Hello,

I am having a problem trying to figure out the cause of a crash I am
getting on my ST.  I originally noticed the problem when I switched
resolutions from low to medium and I got 4 bombs.  I have been trying
to figure out if it is a combination of  programs in the auto folder
and accessories, but have not been able to determine if there is a
conflict or if it is just that a certain number of accessories and
programs causes a 4 bomb error.  Also, I have noticed that a lot of
the time if I switch res with Oat Bran installed, the system will just
hang up.  Screen white, cursor in the top left corner.  I have tos
1.4, a 1040 ST, 2 drives.  Has anyone had a similar problem?  I've
been spending a long time trying to figure out the cause.

Who says Oat Bran's not good for ya?

The problem does not seem to be with Oat Bran itself.  Try booting with no
accessories and no auto-programs except Oat Bran.  Switching resolutions
works fine.  (At least for me, and I have TOS 1.4 too.)  (Actually, I
tried it with Schizo and DC formatter resident as well.)

I noticed that Quick ST (AUTO folder version 1.46) will cause a warm
boot when you change from medium to low res (I didn't try going from
low to medium).  Perhaps this is causing your problem.

Oat Bran doesn't do anything unsafe, undocumented, or unhealthy as far
as I know.  It just installs a little routine at the VBI vector.
(I think it's at $70.)  After the routine exectues, it jumps through
the old vector (i.e., it calls the system VBI routine).

Be wary of programs like Quick ST and formdial that replace certain
parts of the OS.  They sometimes rely on being called first, so if
another program comes before them and steals the vector(s) they steal,
they complain bitterly.  The upshot of this is that the order
things get called in is crucial.  You may have to erase your AUTO
folder and copy the files back in in a different order (with OS
enhancements first) to get resolution changes to work properly.

I have had this problem also.  It is caused by desk accessories and/or
auto folder programs.  The following programs caused a crash on res
change in my system:

WordPerfect Print Spooler (a desk accessory)

ICD clock setting software (an auto folder programm- sets your clock from
	the clock on ICD's host adapter, if you reset the time in the
	control panel, the host adapter clock is updated.  Note that
	there are two versions - the one that does not allow you to
	update the host adapter clock does not cause a crash)

EasyDraw Snapshot ( a desk accessory that allows you to take screen
	snapshots)


It took many hours of removing and reinstalling various combinatoins
of programs to find the culprits.  Any one of the above alone is enough
to cause the crashes.


You will have to find the program or combination of programs that causes
the problems on your system, and boot without them whenever you know you
will change resolutions.

Or you could just use the program AUTOSORT, which will do that for you,
without deleting anything.  Far as I can tell, it reads up the files into
memory, and writes them down in the correct order (yes, that means order
in the directory, not just create-write, as that could produce different
results).  I think I saw it on terminator, could be on panarthea too.

this is a relatively common problem for accessories which patch vectors.
upon res change, the accessories are reloaded, wiping out the originally
loaded accessory, and along with that, the new patched vector code, causing
multiple bombs. if atari somehow notified accessories that a res change was
in process, then the accessories could unhook the vectors they hooked, and
allow a proper transition from one resolution to another with no bombs.


... more wishful thinking by someone who does a lot of thinking ...
