Modifying the Minix boot process involves several steps, and the specifics may vary depending on the version of Minix you are working with.

1. Set Up Minix Development Environment: Download the MInix from here '''(http://lms2.cse.saveetha.in/mod/url/view.php?id=718)'''. Ensure that you have a Minix development environment set up '''( See Video http://lms2.cse.saveetha.in/mod/url/view.php?id=735 )'''. You can follow the instructions provided in the Minix documentation for setting up a build environment '''(See Video http://lms2.cse.saveetha.in/mod/url/view.php?id=737 ).''' this abouve source was given by : dr.gowri ganesh

2. Locate Boot Code: Identify the relevant source code files for the Minix boot process. Common files include boot/boot.asm, boot/boot.h, and /src/kernel/main.c.

3. Insert Your Code: Modify Kernel Initialization (kernel/main.c): Insert code to print a message during kernel initialization. In the following code replace the message "Modified by <>". Here In place of your name please replace your name.

// kernel/main.c

#include <stdio.h>

void main(void) { // Existing kernel initialization code.. printf("modified by karthick\n"); } 4. Compile and Build: Use the Minix build system to compile your modified code.

bash

make build 5. Test Your Changes: Transfer the new bootable image to a test environment, such as a virtual machine or a physical system, and observe the behavior during the boot process.

// Ensure that you are in the directory /usr/src/releasetools make hdboot Copy the code that you made changes in the MINIX
