Assembly Language kernel

I am trying to write a kernel purely in assembly language. How do i go 'bout the development environment and general setup that lets me control what i want it to do?

osdev.org should have all you need.

This website provides information about the creation of operating systems and serves as a community for those people interested in OS creation

To clear it up a little more, apart from all the resources and information on the site, there are two assembly "starter tutorials":

1. 32-bit Assembly Bare Bones
2. Real Mode Assembly Bare Bones

From there its really up to you to explore the wiki more, it has everything one needs, in one basic form or another

I used to be a VAX developer. I'd recommend that you find a copy of VMS microfiche with the exec, written in assembler.
