for my home network. My preferred operating system is FreeBSD and I’m installing the most recent stable release – 7.2.
Installation on a Soekris box is a bit different to installing on a normal PC since it has no video card (it’s headless), and mine doesn’t have a CDROM or DVD drive. There are several ways of doing the installation. One is via a Compact Flash card, another is putting a disk drive into another PC, installing the OS, and then moving the disk to the Soekris box. The way I’m going to do it is by network booting using PXE. There are number of guides to doing this around if you search for “PXE install FreeBSD”. I’m doing it a bit differently since I’m going to use dnsmasq for the BOOTP and TFTP server. The reason I’m doing it this way is that I already have a FreeBSD server running dnsmasq and it’s capable of doing the job without having to install ISC DHCP3 server or a dedicated TFTP server.
Basically, I follow the instructions from this guide with the following differences.
- I didn’t bother building pxeboot in Step 5. Instead, I changed baud rate in my terminal emulator (picocom) to 9600 at the point where pxeboot is running. You get a few garbage characters but it doesn’t really matter.
- Since I’m using dnsmasq from the BOOTP and TFTP server, I replaced Steps 1, 2, & 3 with adding:
to the bottom of dnsmasq.conf. Note that you should replace “/mnt/pxeroot” with the name of the directory where you’ve installed pxeboot and the FreeBSD install image (“/usr/local/freebsd7″ in the guide above).
- I used 19200 baud instead of 115200. That’s the default baud rate of the Soekris boot loader. For the amount of time spent on the console, it’s not really worth worrying about the higher speed.
- Finally, I had something go wrong when it was booting the FreeBSD kernel. It may have been the same problem noted in Step 7 of the guide, I don’t know. Anyway, my solution was to replace the standard FreeBSD kernel with a custom one. I’m building a custom one for the Soekris box anyway, so I just used that. Its config file can be found here. I had to disable the IPFIREWALL options for the installation because it defaults to “deny all” which prevented me using NFS to do the installation!
Anyway, it’s all working beautifully now. I hope this helps somebody else who’s trying to do that same thing. It will also help me remember how to do it for next time!
