FreeBSD is my preferred *nix OS, but if I am not able to get a USB boot solution in a reasonable time, I will have to move my project to a Linux based solution as there are already Linux USB boot systems out there. > > All assistance is appreciated. I think that even if I could get some info on the BSD bootup sequence/etc I might be able to build something workable. I have no experience with USB booting but if your bios is not too exotic, it should be doable. I have created a minimal system you can boot from regular disks, tftp and flash based devices. I suspect it should also be able to boot from USB keys. The trick is to use FreeBSD's boot loader to load a ramdisk image with the kernel. The kernel itself has no knowledge of the boot device, all it knows is / is md0 and there is no need to mount filesystems. This page should give some insights on how to create your own ramdisk: http://www.thinbsd.org/doc.html -- Francois TigeotReceived on Sun Oct 31 2004 - 07:02:05 UTC
