It can also be used to run older software-such as PC games-which will not run on non-compatible, or too fast computers.īochs started as a program with a commercial license, at the price of US$25, for use as-is. Bochs runs on many host operating systems, including Android, Linux, macOS, PlayStation 2, Windows, and Windows Mobile.īochs is mostly used for operating system development (when an emulated operating system crashes, it does not crash the host operating system, so the emulated OS can be debugged) and to run other guest operating systems inside already running host operating systems.

Many guest operating systems can be run using the emulator including DOS, several versions of Microsoft Windows, BSDs, Linux, Xenix and Rhapsody (precursor of Mac OS X). It supports emulation of the processor(s) (including protected mode), memory, disks, display, Ethernet, BIOS and common hardware peripherals of PCs.

Unfortunately, qemu doesn't come with a debugger, and we won't be testing your software with qemu by default.Windows, Linux, BSD ( FreeBSD, NetBSD, OpenBSD, Darwin), OS/2, BeOS, MorphOS, AmigaOS, Android īochs (pronounced "box") is a portable IA-32 and x86-64 IBM PC compatible emulator and debugger mostly written in C++ and distributed as free software under the GNU Lesser General Public License. Qemu is generally faster than bochs and may be more forgiving. d 1 for the first one you set) before you can start stepping through your program.
One annoying feature of bochs as currently implemented appears to be that the step command will not step over a breakpoint! So you may need to delete your breakpoint (e.g. b 0x7c00 will set a breakpoint at the start of your bootloader). The most useful early on is probably the stock breakpoint command b, which lets you specify a physical memory address(e.g. There are several breakpoint commands in bochs-debug. If you just want to run your simulation, type c (for continue). Type help to get a list of commands or see for documentation. The bochs-debug program works exactly like stock bochs, except that it gives a gdb-style command prompt after initializing. Look for common/bin/bochs-debug in your user or group directory this should run on any recent Intel-architecture Linux machine (e.g., Zoo nodes). Luckily, if you are taking CS422 we have already compiled it for you. For CS422 assignments, we will generally supply you with a standard bochsrc file along with the assignment files.īochs runs in debugging mode if compiled with the appropriate files. Bochs will load options from a file with this name by default, or you can tell it to load from a different file with the -f option, e.g. Since having to edit options all the time is annoying, you can save your current options out to a bochsrc file once you have the setup you like. You can then run the emulator using Begin simulation from the main menu. bochsrc file in the current directory, you will probably need to specify at minimum a disk image file using Edit Options/Disk Options. This will pop up a text menu with several options. Type bochs in a terminal emulator window. These notes are to get you started with using bochs on the Zoo machines.
