I had already mailed to mj@atrey.karlin.mff.cuni.cz but got no answer, so i remail as described in the "How to Get Your Change Into the Linux Kernel or The Unofficial Linus HOWTO" Please give me some feed back (damien.benoist@epita.fr) thanks.
kernel: 2.2.17
pb: // 0 does not work with ega/vga adapter and mono display
how to duplicate the pb: compile the kernel with the following options (module or not): - vga console - parallel port use the following hardware: - monochrome display - ega/vga adapter - a // port at 0x3bc
changes: - region size for ega/vga adapter with mono display (12bytes instead of 16).
