TCCBOOT Compiles And Boots Linux In 15 Seconds

Posted by timothy on from the count-to-ten-very-slowly dept.

An anonymous reader writes "TCCBOOT is the first boot loader able to compile and boot a Linux kernel directly from its source code. It can compile and start booting a typical Linux kernel in less than 15 seconds on a 2.4 GHz Pentium 4. TCCBOOT uses the latest version of the TinyCC C compiler."
