Prism54
I have worked on the reverse engineering of the SoftMAC Wi-Fi chipsets from Intersil ("Prism54" chipsets), and used to be a maintainer of the prism54.org website.
I have notably developed :
- p54u, a FreeBSD driver that supported the SoftMAC chipsets.
- documentation about the internals of them (memory maps, on-chip peripherals, ...), obtained by experimentations.
- FreeMAC, an attempt at writing a GPL firmware for those chipsets.
- Microstumbler, a project aimed at autonomous Wi-Fi scanning using only the Wi-Fi card and a couple of external components.
I have now discontinued works related to Prism54 ; and prism54.org now links to p54, which is a more up-to-date driver for Linux and recommended for today's users. For archival purposes, the old project pages can be found here the mailing list archives are here : prism54-devel and prism54-users. Snapshots of the latest SVN revisions have been put here.
