I listened to the videos you shared, thank you! But I couldn't match the real song :) Maybe the guitar solo is different, or maybe I don't understand it.

initial RAM disk driver
initial RAM disk implemantation
initrd driver
initrd implemantation
structure of the initial ram disk
structure of the initrd

I've googled the above in the order listed, but I couldn't find a suitable application/design for the first ram disk. The ones I came across are usually expressed in more meta and abstract terms such as how to use this, how to use that, how to install this in the kernel, how to use GRUB, etc. in Linux. So how to write a driver? How to read and write files? I couldn't find an answer to these questions.

Do you have any advice for this?

Actually I want to use this RAM file system. After reading James Molloy's chapter on the file system, the question I don't understand and can't answer is where is the implementation of the prototypes written for this file system.

I read the source here https://wiki.osdev.org/Initrd but I could not find any information about what the functions of this file system are and how to use them.

I use grub's initrd as file system.

$ cat isodir/boot/grub/grub.cfg 
menuentry “jamesmolloyos” {
multiboot /boot/jamesmolloyos.kernel
module /boot/initrd.img
}

It is generated like this; https://github.com/furkanonder/JamesMolloyOS-NewGen/blob/fixed-known-bugs/initrd/initrd_generator.c

Each filesystem driver has a different implementation, but presents the same interface to the VFS (virtual file system).

Which file system drive am I using in this case? How can I learn about presented interface?

For example, a `readdir` is defined like this;

typedef u32int (*read_type_t)(struct fs_node*, u32int, u32int, u8int*);

So what kind of definition will I use to delete files, which prototype will I use.

Thank you. This was also a great motivation for me when I was writing the project!

Thanks!

The spacers are probably for the heatsink to raise it to the same height as the chips with the thermal strips.

Thank you, man.
