Andre, Please take a look at this article: http://www.freebsd.org/doc/en_US.ISO8859-1/articles/solid-state/index.html Specifically, this page: http://www.freebsd.org/doc/en_US.ISO8859-1/articles/solid-state/x109.html This part of the article explains, in step by step detail, how to boot off of a fixit disk, and build a filesystem on a flash device (either sandisk style ATA device or Disk-On-Chip). It takes you through everything up to and including configuring the ethernet adaptor and using ftp to grab your disk image (instead of dd'ing) (fixit disk does not have dd) The article as a whole describes a different process than what you are doing, but this piece of the article is (I think) exactly what you need. I would be happy to help further if you need it. ----- John Kozubik - john@kozubik.com - http://www.kozubik.com On Tue, 21 Aug 2001, Andre Oppermann wrote: > Hello, > > I've run into a (hopefully small) roadblock here. > > What I want to do is to make a comlete bootable 'disk' image for a > IDE flash disk.
