BIOS transfers control to this first stage bootloader. Boot loaders may face peculiar constraints, especially in size; for instance, on the earlier IBM PC and compatibles, a boot sector should typically work in only 32 KiB (later relaxed to 64 KiB ) of system memory and only use instructions supported by the original 8088/8086 processors.
