+Hopefully your machine manages to print this text.\n\
+If it did, that's great news because I managed to write a partial VGA driver.\n\n\
+Right now, the short-term roadmap is as follows:\n\n\
+* Complete the text-mode part of the VGA driver.\n\
+* Enable interrupts using the PIC.\n\
+* Write a driver for the Intel 8042 PS/2 controller so the OS can receive keystrokes.\n\
+* Once all that is done, it would be desirable to start the switch to userspace so the OS can actually be remotely usable.\n\n\
+Feel free to mess around with the code, although I doubt it will be very interesting at the moment.\n";
