Obviously some compromises needed to be made to get the price down to this level. >From http://elinux.org/RaspberryPiBoard: <snip> 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. You could replace the kernel image with a bootloader image, and that would work fine. </snip> <snip> The GPU blob is an 18MB as an elf file, plus libraries. It does an awful lot. </snip>
