Why should I mess with a working system!? The 2.4 kernel have been working
flawlessly since I got it (pre-installed) about a year ago... Getting a faster
kernel (i.e. 2.6) is only a BONUS, not a REQUIRENMENT!

Well, now you know one that it DOESN'T work for :)

Motherboard rev 283. Don't know the date/rev of the firmware. Forgot to check
while it (the config/setup) was working.

Oki, found it. I was under the inpression that I had a PegasOS 1 (one)
machine. Never understood the 'DUAL' it said on the motherboard. But looking
at the pictures, it's quite obvious that it's a II.

But I'm still in trouble here. It require me to press enter before doing
the update and I can't do that...

Nope, didn't seem to work.

Looks like it.

I can't remember, but does the 2.4 kernel on the PegasOS have anything like
the /proc/openprom the SPARC kernel(s) have? If it does, MAYBE I can hack the
init script(s) to change the {input,output}-device files.

On my SPARC(s) I have the files:

----- s n i p -----
root@aurora:/proc/openprom/options# cat /proc/openprom/options/{input,output}-device
'ttya'
'ttya'
----- s n i p -----

Just MAYBE I can change that to 'keyboard' and 'screen' respectivly by just echo'ing
text to the files and then have it rebooted...

But if I'm not misstaken, last time I tried to _change_ files there on my SPARC(s),
the kernel crashed...
