boot problem

Hi,

I need to restore original windows pocket pc on my ipaq 3970 after linux installation.

 

I find all files that i need but i can’t connect my pocket pc to the pc,

on the pocket pc screen i can only see the image with the pinguin and the write arm bootloader.

 

When I connect the pocket pc with hyperterminal I can’t type load root.

 

What can I do?

 

Regards

Matteo
