You can download the file from the above site - I think this might be the exact reference. Then go to the most recent entry on this site for the secret menu process http://forums.steves-digicams.com/forums/view_topic.php?id=82905&forum_id=24&highlight=A90
Rember to place it on your card at the same level as the DCIM file, not inside it like I did at first. It came zipped so you will need to use Winzip. I will now try and polish this a bit on that site while it is still fresh in my mind.

Despite charging several batteries fully and pressing menu and the power button at the same time, my camera still refuses to operate, and shows just A90 on the screen. It all started when I thought that the batteries weren't fitting properly because the camera said they were depleted!
I sent it back to Pentax who were going to charge about £110 to repair it - so I decided it wasn't worth it. They said the case was damaged, but it looks OK externally. I read elsewhere that A90 signifies a motherboard fault. Although I have given up I am still interested in having one last go. The camera may not be much by todays standards, but I really liked it!
Where is this elusive file?
