Yesterday I had to clear the parameter RAM and since then my mac II is
booting in a different way, though not not showing any other problems.

Before this it would display the "Welcome to macintosh" message in colour
(the small picture) and then proceed loading the inits and displaying their
icons.

Now it displays the msg in monochrome, and just before showing the first
init the screen blinks and the "welcome" msg is gone, leaving only the
background pattern.  The icons continue to appear as normal, and in colour
(Suitcase II).

I tried clearing the parameter ram and cycling the  power repeated times to
no avail.  Using a program called NewPRAM (I  think) recently posted on the
net I examined the  settings  in the parameter ram   and there seems  to be
nothing related to the number of colours at startup.  Maybe there is, but I
would like  to know  which bit/memory position  should  be changed, and how
(don't know how to use macsbug, nor the addresses of this ram).

I know it's something with the parameter ram because even booting from
other systems on floppies (which I keep locked) the behaviour is the same.
Booting from those systems used to display the "welcome" msg in colour as
well.

Details:  mac II, 2 MB, Rodime 140 MB, 8 bit apple video, system 6.0.2

Any suggestions to explain the behaviour and a cure for it much
appreciated.  Replies to my address please, I'll post a summary.
