Start from harddisk

In floppy, sector 1 is a boot sector of floppy but i dont know where is boot sector in harddisk?

Theres multiple places you need to write to on the HDD, in order to boot properly. I've forgotten the actual addresses, but I'm sure I can dig them up from my backups. Gimme a sec.

Nope, couldn't find them. Google is your friend though. Try searching there.

Most of my stuff is floppy only.

Have you succesfully to start from floppy?
I have wrote some program which will show "Test Program" into sector 1 of floppy but when i try to restart and insert my floppy into my computer it isn't
boot from my floppy.

Another, i try to read some stuff from my floppy by using ASM
Can you show me a sample code to read byte from floppy.
I have tried some code but it doesn't works.


Thanks :)

I haven't got anything using ASM. All I wrote for the Floppy, was the actual boot. The rest was in C. I don't think I have it in my backups. Look at some Open Source Operating Systems, such as ReactOS, TinyOS, etc.
