I would like to know what I have to do to start OS dev wholey in pure ASM (NASM to be specific).

Do I just need to make a boot disk?  How would you do this?  What else would I need to do before I get off into writing the kernel (in pure ASM)?  Thanks!

First of all you need a IDEA a goal you want to have for your OS 2.A lot of time Writing an OS Espcially in PURE assembly takes time a whole lot of it ;D 3.You should get more than one coder to help you (freinds, me) you need's a name and someone to write apps for that OS Once you have that all ready you can dig in and start the kernal!  ;) I hope this is what you wanted to know

MenuetOS is made entirerly from assembly. It also is all on one floppy.

As for a boot disk.
You'll need to make a bootsector that you copy to the very first part of the floppy. That will be responsible for finding you kernel and loading it.
Take a look at John Fine's bootsector's for more info:

How do you make a boot sector?  And, I'm going to use John Fine's boot loader to load the kernel.  So, once I get this whole boot stuff (the loader and sector) all figured out, I can start the kernel.

Thanks, fellas!

Just wanted to tell you that I'm a member, now.  :)

Back to the OS questions...

John Fine's bootloader is a bootsector. Simply download his PartCopy program, and follow the instructions in the bootloader/boosector to copy it to a floppy correctly.

Check out my "Copying your Bootsector to a Floppy Disk" under the Docs and Tutorials section on my site for getting a bootsector onto a floppy.

Where's your website?  Thanks!

"The Operating Systems Vade Mecum" is available as pdf download! You can get it from Alexei A. Frounze's site.
