Hi Sri...
That's really useful information you give me there - I was
wondering why the beast is so docile in safe mode, when it totally
hangs in normal boot!
I shall definitely play with this when I've cleared a little space on
the bench for it: it's been put out of the way for now (man are those
things heavy to lift around!)
(Also I'm currently wrestling with the Quicksilver I added to the
fleet last weekend - this runs fine but when it is turned off it sulks
and takes an awful lot of button presses before it gets further than a
bong and an instant shutdown - I will be starting a separate thread
for this LOL!)
I shall also pass these details on to the person mentioned in the OP,
she may wish to try this too, since she (like me) doesn't like
throwing usable kit away!
Although, as I mentioned, I bought this eMac with the intention of
parting it out.........
(which will eventually happen - I have 7 emacs altogether: one has a
faulty IVAD cable, one is totally dead AFAIK, one is on loan to a
friend, one is dedicated to playing R! DVD's, and the other three are
fully functional, including a 1.42 that is my second-fastest Mac!) ,
......... I like the idea of being able to use this one with
relatively full functionality just to see how it copes!
I will report back when I've done this.
All the best, Dan.
