I've check my device out it is :
 1023 : 8500
oh. It may be compromised.

It is a way out for me.. and for others as you say below.

In what part of the code is this writing outp() ? It is not in vgabios.c
is it ? 
i say that that because i believe it was a common file for every
build... 
thanks again.

For the time being, i'am at writing doc and well
this is a needed step, first it helps me understand in the whole,
second i've been ordered to do so.

I would gladly help ... what I could is bringing my doc to you and
LinuxBios people.
But I write it in french since i'll prepare a 'conference'  at
my university based upon it: hey, my intented audience is frenchy.

Moreover, i've led it as a study of project, well sure that's no 
a burden it but for example it's a bit offside the way you 
present the topic in your doc.

But it is detailled, stuffed with example and very newbie friendly, 
at least I could swear :) Though it need some reform to fit your
structure.

Listen, if you or anyone is interested in it, knowing that and, 
is a somewhat good french to english translator I'll share with'
glad to have a early point of view ... and correction.
