 The BIOS then checks the bootable devices for the boot signature magic number. This is located in the first sector which has the byte sequence `0x55AA` at byte offsets 510 and 511. If the BIOS finds this boot sector, it loads it into memory. After its loaded, execution is then transferred to the boot record. On a floppy (which this system is intended to be run from at this current time) all 512 bytes can contain the executable code.

 The bootloader process will be divided into stages, and each stage will have specific responsibilities. Here's a rough outline of my bootloader's structure:

+##### **Stage 1: Master Boot Record (MBR)** ✅
 
 The MBR will be contained within the first 512 bytes of the disk.
 
 - Responsibilities of the MBR:
-	- The BIOS will load the first 512 bytes into memory at address `0x7C00` after the [[Boot Process|boot process]] is completed.
-	- The Stage 1 bootloader's primary job is to load the second-stage bootloader from the disk into memory.
-	- Basic hardware initialization will be performed using [[BIOS Interrupts|BIOS interrupts]] (putting the display into text mode).
-	- A simple message will be displayed, something like "Loading Stage 1..."
-	- We will then load the second stage bootloader (placed in sector 2) into memory.

 To summarize, the BIOS will load our MBR into `0x7C00`. Then we will want to load Stage 2 of our bootloader from disk. A basic message will be printed to the screen, and we will jump to Stage 2.
