Tomato is a small and stable embeded system based on Linux kernel. It can run almost all of broadcom chip based routers. If you would find more detailed information, pls. open the following page.
I have worked at one of the biggest IT companies worldwide for over 15 years. Tomato is only personal interest due to nostalgia that I was a software engineer about 15 years ago. I already did tomato mod from the first version 1.23 by PolarCloud. I like that feeling to share my contribution to others, especially for Chinese who have no free and stable firmwares for many low-end routers. You will find more information at this page.
