CategoryHardware

There are number of open firmware projects, some of which are listed below.

While all the firmware below is open source, some of it uses read-only firmware embedded in ROM chips and some of the read-only firmware does not have freely licensed public source code. Some of the devices in this situation do not have enough RAM that they could completely avoid the read-only firmware in the ROM chips.
