Hi,

As with the other suggestions, along with alt.os.development, might I
suggest a book?

  http://www.fysnet.net/the_system_core.htm

This book shows you how to go from the "power starts, BIOS gets control"
(Hi Auric) to a round robin type task scheduler.  It shows the boot
code, how to write the boot code, how to manage memory, how to communicate
with the BIOS, and other things needed.

It is a simplistic operating system, ready for lots of additions and
improvements, but shows you how to get started.

It also includes many utilities needed to create disk images, write
disk images, get disk information, the a20 line, etc.

Then for file systems, check out Volume 2 in that series.
