There wasn’t much to talk about because of the simplicity. This is a very short post but I hope I did well on this post. Now when you click start your OS should start. To change to booting to a CDrom go back to where you previously selected your image file and scroll down to the bottom of that setting and changed from booting to floppy to booting to CDrom.
Why? The system is booting from a floppy. You could hit start at the top right but the OS won’t boot.

The perk of Bochs is its simplicity when setting it up, but the important settings are the Fdisk A and B master, but since I only used one OS I just changed from floppy to CDrom on Fdisk A and hit new selecting my Slax ISO file.

I did wrote a post on Limbo which is another PC Emulator but the only issue I have is how slow it is and I wanted something faster which came to this really cool even awesomer piece of software written in C++ called Bochs.

It gives me the excellent speed and hardware emulation of qemu, with the more-natural-for-simulation interface of bochs.Before I begin, PC emulators are pretty cool piece of software especially when they allow you to run a full on Linux environment on your phone and not the pain in the BEEP that is Debian NoRoot and GNUroot. The typical use of bochs is to provide complete x86 PC emulation, including the x86 processor, hardware devices, and memory. Bochs provides many different modes of operation, in support of a wide variety of use cases. With this hybrid approach, I can boot the disk using qemu for installing the OS, interactively setting things up via the commandline, downloading packages from the internet and so on, and then reboot into bochs to run simulations. Bochs is capable of running most Operating Systems inside the emulation including Linux, DOS or Microsoft Windows. The only trick is that you have to create the virtual disk using bochs’ bximage program if it’s created with qemu’s corresponding qemu-img program then bochs won’t recognize the virtual disk for some reason. Essentially, it just uses a single regular file as the virtual disk. It took me a while to realize that I could have my bochs and qemu it, too, as both emulators can read and write a common virtual disk format: it’s called “raw” for qemu and “flat” for bochs. qemu is everything I could ask for - if only its codebase was more in tune with what I wanted to do! The Best of Both Worlds

qemu+kvm might even be fast enough to compile code inside the VM, which would ensure that the right headers, libraries, etc are used (otherwise you can always just mount the virtual drive as a regular filesystem and use cp from the host machine).

However, this is a pretty involved procedure, debootstrap with Ubuntu didn’t install any kernels for me, and installing the boot loader also seemed tricky.Ĭontrast these circuitous approaches with qemu, which is very fast (even without using KVM acceleration) and installed Ubuntu without a hitch on the first try. configure -enable-sb16 \Īn alternative approach is to use debootstrap to setup a chroot Linux installation, and then copy that installation onto the virtual hard disk, as outlined here. Ultimately, I found some success when configuring bochs with the command listed below (everything should be on 1 line). Graphical corruption of the terminal in bochs. Don’t even ask about getting networking to work (it still doesn’t), or why the terminal occasionally looks like the picture below. After that adventure I had some kind of boot loader corruption that caused the virtual machine to fail to boot. It turned out that this was due to some funkiness in the bochs plugin system (which is based on dynamically-linked libraries) switching to static linking finally got me past the assertion failure. Not only is it slow, but I encountered an assertion failure (in bochs) during the disk partition step of the installation. It turns out that running the Ubuntu installer in bochs is a real pain. Next came the supposedly easy part: create a disk image with Linux on it (I wanted to use Ubuntu Karmic Server) and start simulating. The quick fix was to remove bochsdrm from nf.
When installing and customizing the latest ISO, manjaro-xfce-21.3.0-220617-linux515.iso, in a Qemu virtual machine, I got an error, 'module not found: ‘bochsdrm’. For the record, I was using bochs from CVS as of (bochs 2.4.2 was the latest release at the time) and qemu 0.12.2. I found the topic below when looking to see if a problem/solution had been reported. Instead, qemu is designed to run a bunch of instructions (really fast) instead of stopping precisely after each one. I also considered using qemu, but qemu’s design was ultimately not a great fit for the do-1-insn-at-a-time model of an architecture simulator. I recently decided to try using the x86 emulator bochs for some of my architecture research, as bochs seems to have a well-structured code base highly amenable to hacking.
