Welcome to Pintos. Pintos is a simple operating system framework for

@code{pintos @var{option}@dots{} -- @var{argument}@dots{}}. Invoke
@code{pintos} without any arguments to see a list of available options.
-Options can select a simulator to use: the default is Bochs, but on the

with a debugger (@pxref{GDB}). You can set the amount of memory to give
the VM. Finally, you can select how you want VM output to be displayed:
use @option{-v} to turn off the VGA display, @option{-t} to use your
second of real time. Simulation in real-time mode is not reproducible,
and options @option{-j} and @option{-r} are mutually exclusive.

alternative to Bochs (use @option{--qemu} when invoking

only supports real-time simulation and does not have a reproducible

instructional operating system from the University of California,
