I was looking at the Bona Fide OS Development website on how to copy a bootsector to a floppy. IT shows you how to copy your bootsector to a floppy disk without losing the dos boot record.

I want to know how to add the kernel to my floppy after I do this with partcopy.

add to bootsector:

jmp short begin
nop
times 0x3B db 0

begin:

times 510-($-$$) db 0
dw 0xAA55

copy to floppy:

partcopy boot.bin 0 3 -f0
partcopy boot.bin 3e lc2 -f0 3e

How to add the kernel to the disk using partcopy and this method?

Okay, you can use PartCopy to put your kernel onto the floppy, but that would mess up the FAT file system on the disk(which, I think you are wanting to keep). Just use Windows Explorer/My Computer to copy the kernel to the floppy.

K.J.

That doesn't work since my kernel is a .bin file and not a .exe or .com file. Is there any other way I can use this or can I just add the parameters that the dos boot record reconiqizes to my bootsector.

I figured it out!. All I had to do was add the FAT Parameter BLock to my bootsector.

If I use this: partcopy os.bin 0 200 -f0
partcopy prog.bin 0 200 -f0 200

IT overrides the dos boot record, But since I added the FAT Parameter Block, the dos boot record wasn't ovewritten by the disk.
