The file /etc/plex86/winnt as distributed by Debian seems
to lack a few plugins. With the following patch things
work a lot better. I will file a bugreport to Debian about this.

Regards,
Bastiaan.

It seems that you did not registered any plugins, ie the
cmos plugin is not loaded, that's why you get : "No handler
defined for port 0x70 and 0x71".

Now, the funny part : current panic IP is A000:0, that is
the video memory, and current instructon is add ahl, [bx+si,
wich opcode is 0000].
Who knows where the execution path come from ? because this
instruction does not branch, and all the memory is filled
with 0 at boot time...

So I think the execution path comes from somewhere below in
memory, and when it gets to the vga memory, Plex86 panics....

Anyway, please register the plugins in plex86.conf, and try
again.

hi,

it seems to be time to fill this group with requests
;-)

I am sure somebody already asked this stuff on th
eold lists - but I have not seen a valid workaround
yet. Could somebody give me a clue about what to
change?

I have compiled latest plex86 source on a SuSE 7.2
with kernel 2.4.17 running on an Athlon 700 with
384MB RAM.


Best regards,

Klaus
