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.

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?
