If you are coming from the PC universe, the Raspberry Pi boot sequence is funky

Read the “RPIforum”:http://elinux.org/RPi_Software outline carefully. No boot rom, no boot loader. Instead:

The boards do not include NAND or NOR storage – everything is on the SD card, which has a FAT32 partition with GPU firmware and a kernel image, and an EXT2 partition with the rootfs.
We’re not currently using a bootloader – we actually boot via the GPU, which contains a proprietary RISC core (wacky architecture). The GPU mounts the SD card, loads GPU firmware and brings up display/video/3d, loads a kernel image, resets the SD card host and starts the ARM.

I was hopelessly confused as to why I needed a kernel image and a system disk image until I read this. It is no goofier than the PC BIOS but is just different.

    Imagine someone coming from this environment, and explaining DOSX.EXE and segments to them….talk about funky.

    indeed, it is just what you are used to.
