I am starting with my first device driver and I'm trying to understand how to load it. Can I use GRUB "insmod" command or something like that for this?
And I also read Device Management article and it says that I can not to write my own drivers but write only an interface for them and use already existing drivers. Am I right?

Thanks for your reply.

GRUB's "insmod" command loads GRUB drivers for GRUB. If you want GRUB to load drivers (or any other files) for your OS, use the "module" command. From your OS, you can access those files through the Multiboot information structure.


Yes. Which interface do you plan to use?

I'm going to use EDI because it's easier to start with, isn't it? According to article about drivers, I can only choose UDI or EDI, or maybe there are some other interfaces?

EDI should be easier than UDI.


According to the wiki, there's also CDI. But you could, in theory, implement the driver interface from any OS to use the drivers from that OS.

I think I got it. Thank you.
