Assembly OS programming tutorial?

[Quarg]

Hello and thanks in advance for any advice. I am interested in writing an OS in assembly, and can't find any tutorials on how to do any of this. So far, I have written a bootloader that prints Helloworld! to the screen. Does anyone know of any tutorials that will get me further than that?

if you can find a copy of the book "Writing a 32bit operating system". The entire kernel is c/intel asm. The c compiler I believe is bootstrapped assembly though.

I know the book is out of print but it would be a good start as well as the wiki pages, which I feel don't cover enough of doing things the hard ways. I do realize much has changed since that book came out but it was where I started researching kernel design.

Food for thought
