Dear All,

I still have the problem of a "fade to White screen
with black bar" on boot 
problem, and as previously posted I have never managed to
get the USB 
networking working.

However, I have managed to build a working serial port
adaptor, and can get 
the kernel output, and a shell

Would I be correct in thinking that the problem is my SD
card ? 
It seems to work fine under Windows Mobile 2005...

All ideas welcome
