![]() Save the following code in a file called loader. This program will write a very specific number 0xCAFEBABE to the eax register. In here we use little bit of assembly code. GRUB will load our operating system to the correct memory location. Because we don’t need to write a lot of low-level codes. We will be using an existing bootloader called “ GNU GRand Unified Bootloader (GRUB)”. The first part of the bootloader will transfer control to the second part, which finally transfers the control to the operating system. But, due to some restrictions, the bootloader is often split into two parts. Develop Android games and deploy them to multiple device types on Android, Chrome OS, and Windows by using the Android Game Development Kit and Google Play. This program’s task is to handover the control of the computer to the operating system. After all, it will transfer the control of the computer to the bootloader. The original role of the BIOS program was to export some library functions for printing to the screen, reading keyboard input etc. After you press the power button, computer will run several programs before handover the control of the computer to the operating system.īIOS program(stands for Basic Input Output System) is usually stored on a read only memory chip on the motherboard of the PC. This will be the emulator that we will be using to debug our operating system.īooting is the process of starting a computer. ![]() We need this package to generate an ISO image file for the file system. For that you have to basically put your Raspberry Pi into the case and screw it if youre using the Flirc case follow the images below. The first thing that you have to do is to assemble the console. Since we are using assembly, we have to use nasm(Netwide Assembler) to compile assembly programs. Step 2: Place the Raspberry Pi Into the Case. ![]() This package contains GNU debugger, g++/GNU compiler collection, and some tools and libraries which are required to compile a C program.
