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 :)
