We get `0xfffffff0`, which is 4GB (16 bytes). This point is called the [Reset vector](http://en.wikipedia.org/wiki/Reset_vector). This is the memory location at which the CPU expects to find the first instruction to execute after reset. It contains a [jump](http://en.wikipedia.org/wiki/JMP_%28x86_instruction%29) (`jmp`) instruction that usually points to the BIOS entry point. For example, if we look in the [coreboot](http://www.coreboot.org/) source code, we see: We get `0xfffffff0`, which is 16 bytes below 4GB.
