This page describes the process of installing MINIX 3 on Bochs.
Please install bochs. Bochs binaries can be downloaded from their webpage. If you're running a Linux distribution, you can install Bochs via the package manager.
Before you install Minix 3, you will need to create a new virtual machine configuration. The VM configuration specifies the parameters of your Virtual machine, e.g., how much memory you want the VM to use, how big you want the virtual hard disk to be, etc.
Now, we will get a notification that looks something like:
The following line should appear in your bochsrc: ata0-master: type=disk, path="minix.img", mode=flat, cylinders=4161, heads=16, spt=63
Make sure you write down all these values, because we will need them later.
Now, copy the VGA and BIOS rom images that were included in the Bochs installation, to the current directory. Depending on the Linux Distribution you use, the image are either under /usr/share/bochs or /usr/local/share/bochs
cp /usr/share/bochs/BIOS-bochs-latest BIOS-bochs-latest cp /usr/share/bochs/VGABIOS-elpin-2.40 VGABIOS-elpin-2.40
Next, we have to create a file called bochsrc.txt. You can use any editor you like for doing this.
Copy in the file the following
romimage: file=BIOS-bochs-latest megs: 256 vgaromimage: file=VGABIOS-elpin-2.40 floppya: 1_44=floppy.img, status=inserted ata0-master: type=cdrom, path=minix_R3.2.1-972156d.iso, status=inserted ata1-master: type=disk, path=minix.img, cylinders=4161, heads=16, spt=63 log: out.bochs mouse: enabled=0 cpu: ips=15000000 boot: cdrom
Make sure that line 6 is exactly the same as the notification you got earlier after creating the disk image, and that the path in line 5 exactly matches the filename of the minix image you downloaded or will download.
The last line
indicates that the virtual machine will boot from the cdrom.
Assuming you have downloaded and decompressed a MINIX 3 ISO image from the download page, you can now run bochs and install MINIX.
In order to do that, type
In the menu, press number 6. Minix 3 will now boot.
Then you can follow the normal installation instructions.
When the installation is over, type
to exit Minix. When you get the fd0> type off in order to shutdown the Virtual Machine.
Now you have installed MINIX 3 on the virtual machine. First thing that needs to be sorted, is that next time you boot, you want to boot from the operating system, and not from the CD image. Edit the bochsrc.txt file,
# vim bochsrc.txt
and change the last line to
Save the file, and in the command line, type
to boot MINIX 3.
You should read Post Installation for some configuration tips.
Here you find can some additional details on how to setup bochs under freebsd.
You might want to install bochs with the –with-term option ( Use text-only gui with curses library ). As most probably you wont have X installed.
In my case I disabled the X and enabled term:
/usr/ports/emulators/bochs]# make config
In the menu I have this ( you can check other options as you like of course):
... [X] TERM Use text only, console based interface ... [ ] X11 Use X11 display interface ...

[pomelo@brain /mnt/storage2/minix]$ cat bochsrc.txt romimage: file=BIOS-bochs-latest megs: 64 vgaromimage: file=VGABIOS-elpin-2.40 floppya: 1_44=floppy.img, status=inserted ata0-slave: type=cdrom, path=./minix.iso, status=inserted ata0-master: type=disk, path="minix.img", mode=flat, cylinders=4112, heads=16, spt=63 log: out.bochs mouse: enabled=0 cpu: ips=15000000 boot: disk ne2k: ioaddr=0x300, irq=7, mac=b0:c4:20:00:00:00, ethmod=fbsd, ethdev=xn0 ###END###
Since I only have TERM compiled as display option it will use it by default.
