Well, on most cards, if you are using a 8-bit mode and you don't redirect the output from the child process, it will show up on the screen. I haven't seen any cards that do it correctly on a 24-bit mode (or 16, or 32), but they may exist. There are VESA calls which tell whether your graphix card supports it for any particular mode. -- (\/) Rolf Campbell (\/)
