There are various filters I want to put into print screen, such as quoting graphics characters (for my specific printer), but the above mentioned interrupt remaps INT 05 for its own purposes. There's a bug in the remapped code which causes it not to work if the screen width is over 128 characters, so I would want to take it over anyway. My system: Everex Step 386/20 main BIOS (C)1987AMI Video BIOS extension "IBM COMPATIBLE.*EGA BIOS V1.54 Copyright Everex Systems Inc." Everex EGA card (obviously) EverVision monitor 2 Mb memory Dos 3.3 Thanks for any information you can give. --------------------------------------------------------------------------------- a_rubin@dsg4.dse.beckman.com .signature file under construction Me?
