-The first two patches are needed for Bochs to properly compile and run
-under Solaris on Sparc. If you're not compiling on Solaris, don't
-apply them. The first should probably be handled by Autoconf; I'm not
-sure why it isn't. The second is needed to make GCC accept X.h's
-frequent use of "extern foo(...)", because use of an implicit int
-return type is forbidden in C++.
-
-The third patch makes the gdb stubs work on Solaris/Sparc, by doing
-proper byteswapping. It should be harmless elsewhere.
-
-The fourth patch enables the serial device under Solaris and disables
-tty setup at the same time. Tty setup is a pain when you want to
-connect a serial port to stdout and it doesn't work under Solaris
-anyway. This patch is useful everywhere with `pintos', but may not be
-wanted elsewhere.
-
-The remaining patches add the `jitter' feature described in the
-project documentation, in which timer interrupts are delivered at
-random intervals.
-
-To apply all the patches, cd into the Bochs directory, then type
- patch -p1 < $PINTOSROOT/src/misc/bochs-2.1.1.patch
-You will have to supply the proper path to the patch, of course. You
-can provide the --dry-run option to patch if you want to test whether
-the patch would apply cleanly before actually patching.
-
-To apply a subset of the patches, use a text editor to delete the
-unwanted patches, then follow the above instructions.
-
-Here's a ./configure invocation for Bochs that works optimally with
-the `pintos' utility:
- ./configure --with-x --with-x11 --with-term --with-nogui
-If you want the gdb stub, add --enable-gdb-stub
-If you want the internal debugger, add --enable-debugger
-
-Here are the commands used to build and install all the versions of
-Bochs we make available on the elaines:
-
-cd /tmp && tar xzf ~/bochs-2.1.1.tar.gz && cd bochs-2.1.1
-patch -p1 < $PINTOSROOT/src/misc/bochs-2.1.1.patch
-PREFIX="/usr/class/cs140/`uname -m`"
-CFGOPTS="--with-x --with-x11 --with-term --with-nogui --prefix=$PREFIX"
