See > > http://github.com/dwelch67/raspberrypi/armjtag > you should be able to netboot from bsd why use linux Because no bsd runs on the raspi as yet but linux does! There is no u-boot or netboot on it either. The GPU loads a file called kernel.bin from a FAT partition. So the idea is you boot linux on the raspi, scp an elf binary file you want to boot from (or nfs mount a freebsd filesystem on it) and kexec() this file. It is upto the binary what happens next. This binary can be *BSD or netboot. In fact different people can work on each in parallel. Once either is ported, you can bypass linux.
