Building your own operating system

Writing your own operating system.


This File contains a boot sector,
that was Created from BOOT.asm 

This is the Boot Program.

When you boot your computer with this
program this would happen.

1) You would get a message like this

	Ready to start Loading the OS...

2) Press any Key

3) After he finishes reading a track he would
	Display a string like this "~~~~" and 
	he would wait for a key struck.

4) After he finishes reading 5 Tracks he would print
	a Message "Done."

5) Thats it.

Like that I compiled BOOT.ASM with TASM & TLINK.

This is the EXE from were I Took the BOOT sector.

(It seems that in WinXP you can't use EXPLORER to
delete an 16 bit exe, so to delete BOOT.exe Make 
a bat file in write to it "Del BOOT.exe"

If you see an extension like this *.abc_exe rename
it to *.exe  (I added abc_ because I couldn't mail 
exe files).
