I suspect that the problem is that the PSU voltages do not fal off to zero volts until the machine has been left powered off for a while. I suspect that, because the PSU voltage has not fallen to zero, it is holding some bit(s) at '1' which is preventing a proper cold-power up reset. If my Iyonix crashes, sometimes the rest button never works, no matter how many times I try it. Switching off at the back, and then back on again after only a few seconds does not allow a proper power on reset, for the reason outlined above, unless I wait 3 mins or so before powering up again. As I say, I suspect the 3 mins is the required time for the PSU (especially for the beefier higher power PSUs now supplied as replacements) to fully discharge, and thus affect a cold-power-on. -- Cheers Roger Atomic Software http://atomicsoftware.org.uk/ Isotope Info http://rogerarm.freeuk.com/rogerarm/ Wild Flowers http://wildflowerfinder.org.uk/ Bury Walkers http://burystrollers.org.uk/ Lonely pen tops.
