I used the advice to get the 1.6 installation, and that worked. So now I
have a 'working'
environment and can be somewhat assured that the board is capable of
running such things
as NetBSD and Linux.
I'm going to look into this further and see if I can instrument the 2.0
boot to see exactly where
it is failing.
Also, on the board that I'm using, I can have the BIOS use a serial port
rather than the video
screen, so my current NetBSD boot setup is to use the COM port as the
console, so I can
capture any 'fleeting' message that goes by. This is not possible when
using the video console,
and may explain some differences.
