The Belkin F5D7630 is a router with integrated adsl / adsl 2+ based on the Belkin F5D7230-4 router. There is interest in having an open firmware running on this platform. As OpenWRT is the starting point for most new Broadcom customers, and as OpenWRT's FAQ links to this page, hopefully, information can be provided here to those who have purchased Belkin's as well as those wanting to contribute to opening this platform.
This router is also sold in Europe in 2006 and 2007 under the brand Micradigital, with the revision F5D7630ec4. See http://www.micradigital.com/Product.aspx?id=216719.

NOTE: Use the tftp installation method. Web interface upload is problematic since Belkin use a firmware header like linksys, but OpenWRT doesn't provide firmware images for belkin. The standard openwrt-brcm-2.4-.trx images get rejected by the device. Belkin's customisations to the firmware add the ability to specify nvram settings as a footer section to the firmware. It should be possible to create a Belkin specific firmware that can uploaded via the Belkin web interface by following a method similar to that in this paper http://midnightcode.org/papers/OpenWRT%20on%20the%20Belkin%20F5D7230-4.pdf
The OpenWRT community for making OpenWRT.
Belkin for making a nice, cheap router.
There are a number of public forums and web sites where the installation of open source firmware for the Belkin F5D7630 is being discussed and published.

A good deal of documentation has been published in the public domain, regarding the Belkin F5D7230-4. Most of this has been in the forums (above), but some has been collated in the documents below.
If you have done something that you think might help someone else, write it up and post a link here!
In this paper the Belkin F5D7630 is explored for its availability as a fully integrated wireless firewall router and VPN end-point. This work must be done in order to achieve a best-practice security solution in the Small Office / Home Office (SOHO) price-point. Where, while almost all of the casual risks are equivalent to those experienced by large enterprise, no mitigation technologies are available at an appropriate cost. By collating a mass of publicly available information, the paper concludes by providing a root shell into the device, and a number of Linux-based reports on the hardware make-up of the router. It is hoped that this information can be used to adapt the OpenWRT embedded Linux distribution, for this Belkin router.
By collating a mass of publicly available information, and experimenting with a single unit, the paper concludes by providing a physical console into the device, providing local root user level access, and a schematic diagram for a solder- less project that will allow individuals to try this experiment for themselves. It is hoped that this information can be used to debug open source firmware and to then adapt the OpenWRT, and Sveasoft, embedded Linux distributions for this Belkin router.
Belkin published the Broadcom reference firmware; a small Linux distribution, designed to act as a proof-of-concept and development environment for the Belkin engineers. To minimize the amount of experimentation required to adapt the OpenWRT and Sveasoft firmware for use on the Belkin, the published Broadcom reference firmware was compiled to see if it was functional, and able to provide driver and configuration information for the open source distributions. *.. Furthermore, this process was developed rapidly due to the excellent work performed by Rick Bronson.
