Kirill,
Creating a new module is the easy part. As a newbie myself, recently I
found this blog helpful: http://blog.fpmurphy.com/2010/06/grub2-modules.html
.
As far as writing C or assembly code to talk to the LPT port, there are
plenty of articles out there (like this one:
http://logix4u.net/Legacy_Ports/Parallel_Port/A_tutorial_on_Parallel_port_In
terfacing.html ) that show what I/O addresses are generally used for what.

Subject: LPT
Hello,
I have a motherboard with LCD indicator attached to it's LPT port. I would
like to make grub show
some early splash screen on it. All the things regarding protocol and pin
assignments are ok, as I
already have a programm to show stuff on LCD from OS (Debian). So the
question is "how to make a
grub module that is capable of setting levels on LPT pins?" and a second one
is "how to make use of
it during bootup procedure?
Thanks in advance,
Kirill
