Re: Focus Drive problem

["Giorgio Ungarelli" <giorgio@ungarelli.net>]

Thanks for the suggestion, Ed.

However even if the "new" Focus drive is the only slot used (except,
obviously for the 4MB RAM card) it still won't boot as per the symptoms
described below.   I therefore doubt that it is a power problem (I also have
a System Saver running on top of the IIGS, just in case).

Any other suggestions?
