The solution is slightly nontrivial, unfortunately. Basically, you will need to tweak the part of the PicoBSD build process where it generates a 1.44MB image, and have it generate an image that contains a partition table. (See the stuff in the vnconfig manpage about this.) Keep the image under 1.44MB, so that you can still put it on a floppy. Then you can dump this on top of the flash disk using something like rawrite. You may need to roll some custom utilities for this. A slightly easier solution would be to get a PC104 IDE adapter, and use an old IDE disk to transfer stuff around. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-small" in the body of the message
