What I do is this, say all your graphics are in the .pcx format.
Write a small proggie working in a 16 bit display mode to load each of
the .pcx files as you load them copy them into a big bitmap, when all
the .pcx files have been loaded and copied to this big 16 bit bitmap
save it to disk.
Then I load it into a paint program and reduce the number of colours to
256, voila one palette that contains a good spread of all the colours
needed.
Then you've got to remap all your original .pcx files to use this
palette.
I used the above method because it worked best in my situation, might be
different for you though.
In which case check the Allegro site there's a palette merger program
there, but I haven't used it.

No idea, does the border appear in Windows or any other programs??
I've got buttons on my monitor to stretch the display to use the full
monitors screen area.
