How can i put my kernel to 1000h:000 ?!

[KiBOrG]

I have bootloader a it loaded some soctors from diskette
a then jump to 1000h:0000 and i dont know how i can put my kernet there.

Please Help me,

when you know some url with os turorials
please send me it.

Thank

Why not just tell the BIOS, instead of loading it wherever you told it to, to load it to 0x1000:0 ?

If you're looking to relocate data loaded with the BIOS, look into the stosb instruction. Although really, the address you're using isn't above the 1 meg mark, so you don't need to, just tell the BIOS to put it there; it can, and you don't have to move it.

es:bx, I think it is for the BIOS.

To put your kernel at 1000h:000 you should compile it and relocate its "text" segment to 10000h(segment*10 + offset).For example linking the kernel using GNU "ld" you should use the following command :

ld -Ttext 0x00010000

That doesn't put the kernel to 0x1000:0000, now does it ? If I'll do that, but the bootloader does load it to 0x2000:0000 it will be put to 0x2000:0000.
To put it to 0x1000:0000 you should set es to 0x1000 and bx to 0 before the actually loading.
And if you're using C/C++/any high level programming language/ you should link it to 0x10000.

dd if=kernel.sys of=/dev/mem seek=65536

Thats what I meant.I didn't say the kernel will be put there I only meant that when the bootloader puts the kernel at 1000:000 and execute it,the kernel will look for code at 0x1000.

I think you blindly copied the loading sectors (if not the whole bootloader) code from somewhere and said you have a bootloader. I suggest you write your own or even just study the code.

By the way to put the kernal at 1000h:000 do what DennisCGc said:
