To build xv6 on an x86 ELF machine (like Linux or FreeBSD), run "make".
On non-x86 or non-ELF machines (like OS X, even on x86), you will
need to install a cross-compiler gcc suite capable of producing x86 ELF
binaries. See http://pdos.csail.mit.edu/6.828/2011/tools.html.
binaries. See http://pdos.csail.mit.edu/6.828/2012/tools.html.
Then run "make TOOLPREFIX=i386-jos-elf-".
To run xv6, you can use Bochs or QEMU, both PC simulators.
Bochs makes debugging easier, but QEMU is much faster.
To run in Bochs, run "make bochs" and then type "c" at the bochs prompt.
To run in QEMU, run "make qemu".

To create a typeset version of the code, run "make xv6.pdf". This
requires the "mpage" utility. See http://www.mesa.nl/pub/mpage/.
