+# Worksheet 2
+
+This is my README for Worksheet 2. As you will see from the file and the amount of content within it, I have really struggled during this worksheet and have done what I can (which I'll admit isn't much). Coding is extremely hard for someone who has not done much of it before.
+
+I scraped through last year by the skin of my teeth as I had help from Nathan and other staff. However, this year, trying to juggle work life, uni life, and family situations, I have not been able to do the same.
+
+In order to get to the end of the first task, I have followed the Tiny OS book.
+
+## Important points from the code:
+
+```assembly
+MAGIC_NUMBER equ 0x1BADB002 ; Multiboot magic number
+```
+The `MAGIC_NUMBER` is a constant that represents the Multiboot magic number. This number is important because it serves as a signature that the bootloader checks to determine whether it is loading a Multiboot-compliant kernel. If the magic number is correct, it ensures that the kernel is being loaded in a compatible environment.
+
+```assembly
+loader: ; Entry point
+ mov eax, 0xCAFEBABE ; Move 0xCAFEBABE into EAX
+```
+In this snippet, the code is moving the hexadecimal value `0xCAFEBABE` into the `EAX` register. This value is often used as a marker or identifier, and its presence may be crucial for subsequent operations in the boot process, indicating that the loader has successfully executed.
+
+### Running the OS
+
+```bash
+qemu-system-i386 -nographic -boot d -cdrom os.iso -m 32 -d cpu -D logQ.txt
+```
+
+With the kernel (os.iso) all set and ready, it's time to unleash it into the wild. This time, we’re not sticking to the conventional methods found in textbooks; instead, we’re diving into the world of QEMU. As a powerful open-source machine emulator and virtualiser, QEMU opens the door to endless possibilities.
+
+Using this versatile emulator, we can fire up our machine without breaking a sweat or interrupting our workflow. It's like having a virtual playground where we can experiment freely. Plus, it lets us track the machine's execution in real-time, ensuring we can verify that EAX gets its moment in the spotlight. Get ready to make some magic happen!
+
+#### SIDENOTE
+
+It's a little heartbreaking that I couldn't compile all the steps for this worksheet just yet—consider it a bug in my coding journey. I'll definitely be tackling those remaining tasks later, and I’ll recruit some help to peer-review them because I thrive on challenges! However, I recognise that I need to debug my understanding of coding before diving back in. So, feel free to revisit this repo down the line to see if I’ve added any patches or updates!
+
+```c
+#include <stdio.h>
+
+int main() {
+ printf("Coder is broken\n");
+ return 0;
+}
+```
+
+Thanks for checking out my work! And as always, remember:
+
+MAY THE ODS BE EVER IN YOUR FAVOUR!!!
+
+Cheers,
+DANIEL KIBBLEWHITE
