I've got the ELKSibo stuff (that Alistair merged into /arch/i86) building
and running up to the point of loading and running init (or shell). But I
don't really understand how the ELKS system actually works.
Here is a Runlog (with all the debug printing turned on), can anyone give me
some pointers as to what might be happening??? The machine crashes (stops
doing anything) at the end of this lot.
<<runlog.txt>>
Alistair:- I know you're busy until the Christmas break, I'll tar up what
I've done and stick it on my web site. Hopefully I'll be able to get a few
days hard coding over the break.
Others:- If anyone has a series 3 (a, c, mx or siena - I want this to run on
a seina!!!!) and want to hammer it over Christmas please email me at home
([EMAIL PROTECTED]) and I'll try to explain what I've done with
the code
