If you get a coloured screen on boot-up
(eg. grey, dark grey, blue etc.) then the Amiga
has halted the self test due to a hardware
failure of some sort. You would also see the
Caps Lock LED blink a few times aswell. The
colour shown when it freezes along with the
Caps Lock LED flashing is used to work out
what the problem is.
I can post up more details if you are interested?
There is also a "recoverable error", which
gives you a Guru Meditation screen, but with
a message similar to "A non-fatal error has
occured. Press mouse button to continue".
However, apon pressing said mouse button you
can continue.... for about 5 seconds until
the same Guru screen pops up, so you end up
having to do a warm reset anyway!

just went
through an
error dump (Guru Meditation) when low-value CPU
traps triggered.
Like a blue screen?

It was thus said that the Great aliensrcooluk at yahoo.co.uk once stated:
No, a Guru Meditation has a completely black
screen with a rectangle in white/grey at the
top of the screen.
Inside the rectangle is a message a long the
lines of "A fatal software error has occured.

is the error code, typically 80000001 or 80000003,
but I don't know what the 2nd number represents.
The second number is the address of the task structure of the offending
program. You can also hook up a terminal to the serial port (9600 8n1) and
get into a very rudimentary monitor to help trouble shoot what the heck
happened. I also have (had?) a list of what the various error codes were.
I even wrote some library code that would catch exceptions (that most
often would lead to a Guru meditation) that would allow you to either guru
out, or continue running the program. It's for AmigaOS 1.3 but if anyone
wants a copy ...
