![]() Starting from the top of the file under the section ROMIMAGE, verify the location of the BIOS-bochs-latest file. Comment out everything below the example section by adding a # character in front of each line, then add the line as suggested by bximage above. Scroll down to the ATA-MASTER, ATA-SLAVE section. bochsrc file in your favorite text editor. In the session above I used bximage to create a 500MB drive named c.img. bochsrc:Īta0-master: type=disk, path="c.img", mode=flat, cylinders=1015, heads=16, spt=63 The following line should appear in your. I will create a 'flat' hard disk image with flatĮnter the hard disk size in megabytes, between 5 $Id: bximage.c,v 1.19 1 01:20:00 cbothamy Exp $ĭo you want to create a floppy disk image or a hard disk image? From the base directory issue the following command: bochsrc, which resides in the base directory.īefore you can install an operating system using the new emulated hardware, you need to create a virtual hard disk. The Bochs operating environment is regulated by a single file. Then change to the super user ( su) and issue the make install command. After configure has finished checking and generating the make files, issue the make command. The configure command tells Bochs to prepare the make files, enabling the network card and the CD-ROM. The source package is a better option, as it allows you to specify various options during install.Ĭhange to the directory which houses the tarball, untar it, and run the configure script: For Linux, you can download either the source package (.tar.gz) or the RPM. You can download the latest release of Bochs, 2.1.1, in various packages for various environment. But Bochs is an ideal teaching tool for operating system classes. Unfortunately, you need high-performance top-of-the-line hardware to use the emulated environment productively. The Bochs Web site says that Bochs is an ideal operating system and application testing environment. However, hardware emulation deals a massive blow to the performance of the non-native operating systems. Bochs enables you to install Windows on a SPARC workstation or Debian on a Mac. Bochs (pronounced “box”) provides I/O emulation for a computer’s standard parallel port, serial port, VGA card, disk, CD-ROM, timer chip, and network card, along with a custom BIOS.Įmulating the x86 hardware is Bochs’s strongest point. It emulates 286, 386, 486, Pentium, Pentium Pro, and AMD 64-bit CPUs, fooling the guest OS into thinking that it’s running on real hardware. And none of these alternatives run on Macintosh or SPARC-based hardware.īochs, an open source project, may be a better answer. WinLin does a little better, but it doesn’t support Windows NT, 2000, or XP. Wine, on the other hand, though free, supports a very limited number of applications, and the same can be said about CrossOver Office. ![]() VMware is a (costly) commercial application that lets you run a guest operating system on a Windows or a Linux installation. An open source project called Bochs may be your best option. And yes, you want to keep the costs to a minimum. For now, it's just untapped potential that is only good for simple tasks and exploration.What if you need to run your legacy Windows application on a Linux box, a Mac, or a Solaris-based workstation? To make the equation even more interesting throw in a few requirements - add transferring old legacy accounting data over the network, or using the backed-up data from a CD-ROM. Hopefully, these things can be addressed in the future. Running programs can be hit-or-miss, and the poor file format support holds it back. Nice concept, limited applicationĪll in all, Bochs' concept of being a multi-platform emulator is great, but the execution still needs work for it to become truly useful. Also, if you plan on plugging in storage devices, file format support is very limited, and there's a high chance it won't even be recognized at all. Having said that, the experience of running such applications has been inconsistent and unreliable. In addition, as long as your device can handle it, you can even install and run native programs for testing purposes. From there, you can do all types of tasks and explore features that a particular OS or version is capable of. As for operating systems, you can test out multiple versions of Microsoft Windows, DOS, and even Linux. This tool can emulate various hardware configurations from both Intel and AMD CPUs, common I/O devices, and a custom BIOS to run it all. If you're looking to try multiple operating systems across various platforms, then Bochs is one option to consider that supports all kinds from different hardware combinations and eras. Nowadays, even mobile devices can run emulators with relative ease and quite well. It used to be that PC emulation was reserved for the most capable machines with powerful hardware and specifications.
