This first block of code is the entry point of the program. It is where the BIOS transfers control. First, it makes sure that the string operations autoincrement its pointer operands (the `cld` instruction) footnote:[When in doubt, we refer the reader to the official Intel manuals, which describe the exact semantics for each instruction.]. Then, as it makes no assumption about the state of the segment registers, it initializes them. Finally, it sets the stack pointer register (`%sp`) to ($LOAD = address `0x7c00`), so we have a working stack.
El primer bloque de código es el punto de entrada del programa. Es donde la BIOS transfiere el control. Primero, se asegura de que las operaciones de cadena autoincrementan sus punteros a los operandos (la instrucción `cld`) footnote:[Ante la duda, el lector debe consultar los manuales oficiales de Intel, que describen la semántica exacta para cada instrucción:.]. Después, como no asume nada acerca del estado del los registros de segmento, los inicializa. Finalmente, establece el registro del puntero de pila (`%sp`) a ($LOAD = address `0x7c00`), de forma que tenemos una pila funcional.

Next, the destination register `%di` is copied to `%bp`. `%bp` gets the value `0x800`. The value `8` is copied to `%cl` in preparation for a new string operation (like our previous `movsw`). Now, `stosw` is executed 8 times. This instruction copies a `0` value to the address pointed to by the destination register (`%di`, which is `0x800`), and increments it. This is repeated another 7 times, so `%di` ends up with value `0x810`. Effectively, this clears the address range `0x800`-`0x80f`. This range is used as a (fake) partition table for writing the MBR back to disk. Finally, the sector field for the CHS addressing of this fake partition is given the value 1 and a jump is made to the main function from the relocated code. Note that until this jump to the relocated code, any reference to an absolute address was avoided.
Después, el registro de destino `%di` se copia a `%bp`. `%bp` toma el valor `0x800`. El valor `8` se copia a `%cl` en preparación para una nueva operación de cadena (como nuestro `movsw` previo). Ahora `stosw` se ejecuta 8 veces. Esta instrucción copia un valor `0` a la dirección apuntada por el registro de destino (`%di`, que es `0x800`), y lo incrementa. Esto se repite otras 7 veces, de forma que `%di` acaba teniendo el valor `0x810`. De forma efectiva, esto borra el rango de direcciones `0x800`-`0x80f`. Este rango se usa como una tabla de particiones (falsa) para escribir el MBR de nuevo en disco. Finalmente, el campo de sector para el direccionamiento CHS para esta partición falsa se le da el valor 1 y se realiza un salto a la función main desde el código que se ha trasladado. Date cuenta de que hasta el momento del salto al código trasladado, se ha evitado cualquier referencia a una dirección absoluta.
