This is the machine:

    Mac IIci 
    8M RAM
    40M Apple HD
    Daystar Digital cache card
    Asante Ethernet card
    Apple 2 page monitor
    Apple 2 page monitor card (precursor of 4*8, etc)

With the advent of 32 bit mode System 7 and relatively inexpensive 4M simms,
we have been considering upgrading our machines to 32M.  I installed System 7
on one machine so that we could check out which applications work.
(32 bit mode, no VM)

Problem is that one of our programs not only hung the machine, but put it
into a state where it could no longer be booted in 32 bit mode. 
Reinitializing the disk and reinstalling System 7 didn't make a bit of
difference.

Playing around with Control Panel settings DID fix the problem... the
first time.  Of course I wasn't satisfied with breaking things once and
eventually
ran that same application a second time (FYI MACL 1.3.2).  Now, of
course, nothing I do succeeds in getting this machine to boot in 32 bit
mode.

The machine gets a happy MAC, puts up a double edge window the size of
the "Welcome to Macintosh" window, hides the cursor, and hangs.

I have two theories

Theory 1: Parameter RAM getting set to some bogus value.
Theory 2: Non-Apple cards and/or older monitor card not compatible.

I don't know how to test Theory 1, and would like some feedback before
yanking out cards to check Theory 2.  Ideas, anyone??
