I'm currently working on a mail about this (I've been doing that since
you told me to hookup a serial console a couple of months ago :)
I'm busy, and getting 2.6 up and running on the PegasOS is quite
low-prio. Although it just jumped up to first place. The PegasOS is
the only machine I have that can display X 'correctly' (i.e. with
enough speed to be usable :).

That IS the debian kernel! That's the weird part! _MY_ kernels get
some de-compression errors (can't remember which though).

That was what I tried. That is usual behaviour on SPARC, and the Open
Firmware is 'almost' the same (just not as good if you ask me). Before
I even tried redirecting i/o, I tried to just remove the keyboard - nothing...

Tried that, didn't work. I later found a page that described 'in
detail' how to do this, and I saw that I was missing the speed (etc)
option to the 'devalias' command. Also, I used 'setenv', while the
page I found said to use 'install-console' and then the FORTH stuff.

That was what I thought as well, but I couldn't find anything
about that...
Do you have one you can send me?

As soon as I can get 2.6 working, I will :) But every single 2.6
kernel I've tried have failed to boot for one reason or other...

Hmmm! Thanx. That helped. NOT :)
I can't see squat, and nothing I type seem to work/get through.
What's weird though is that I found a reference to 'F1' after
first keyboard blink. That seemed to stop the boot process...
I guess I can try 'type in the blind'. I've done quite extensive
repairs without any display :)
