On the ~picobsd home page there is a line: Here you can find information on specific projects...: * A Practical Guide to Building Embedded FreeBSD System. (Not yet available) But, since the page was last updated five years ago, is it possible that the doc has since come out? If not, can I ask here about steps to take? I've tried following the instructions in the picoBSD doc/intro.html and how2build.html files, but I can't seem to get the steps right for booting a RAM resident image. 1) I need to build a PicoBSD system that will boot from a flash device (SanDisk at the moment, may need support for M-Systems DiskOnChip later) 2) The system will run out of RAM, there will be no HDD available. 3) The flash will have two partitions, the boot image and compressed memory-resident runtime will be stored in the lower, read-only one. The upper one will be for precious data required across boots. Thanks for any help anyone can give me! Regards, Richard
