I believe this to be the way the ogo is set up. I will check.

I am new to this, but capable of learning. Could you elaborate? What am I looking for?
In what ways would the image files need to be changed? What is this loader? Is this
a DOS executable that I have to compile for an 8086?
Also, were you successful with the HP200lx? Do you know what uP this is using?
I wonder how close your source/etc would be to what I need? What did you use to
boot to elks? Did you have this loader? Did you have to compile this loader special?
What sort of parameterization was required. I have been unable to find this stuff on
the various elks pages. If it is there, feel free to point me to it with a slight
reprimand! [grin]

How would I know? Once I set to boot into DOS mode, I always boot to DOS mode.
(Uless I let all my batteries die and the system restarts. Not a bad safety feature
but I suspect could get old...)
Is there anything I could do to check?

Not really much technically available for the ogo. It was when I stumbled on the
detailed
datasheet for the vadem chip that the ogo is based on did I think of trying this. In
fact it is
quite dusty sitting in a drawer awaiting batteries and the weekend for me to play.

Willing to give it a shot!
Thanks again,
