layout: post title: "Bochs" subtitle: "In two versions" tags: [osdev] For testing out my os during development, I usually use [Bochs](http://bochs.sourceforge.net) I also usually compile Bochs into two versions. One that has the debugger option enabled and one that runs entirely in a command line environment. Let's go! $ curl -L -O http://sourceforge.net/projects/bochs/files/bochs/2.5.1/bochs-2.5.1.tar.gz $ tar -zxvf bochs-2.5.1.tar.gz $ mkdir build-bochs $ cd build-bochs $ ../bochs-2.5.1/configure --enable-smp --enable-cpu-level=6 --enable-all-optimizations --enable-pci --enable-vmx --enable-logging --enable-fpu --enable-sb16=dummy --enable-cdrom --disable-plugins --disable-docbook --with-term $ make all $ make install And that's the terminal version. ### Important note This configure line won't actually work. I'll update with the new one as soon as I can. Now we move this to *bochs-term* and compile the version with the debugger. $ mv /usr/local/bin/bochs /usr/local/bin/bochs-term $ rm * $ ../bochs-2.5.1/configure --enable-smp --enable-cpu-level=6 --enable-all-optimizations --enable-pci --enable-vmx --enable-logging --enable-fpu --enable-sb16=dummy --enable-cdrom --disable-plugins --disable-docbook --enable-debugger --enable-disasm --with-x11 $ make all $ make install Finally, copy the bochs bioses to a public place $ cp -r ../bochs-2.5.1/bios /usr/share/bochs And that's it.
