how do i do this:

- make a output % 512 = 0 [ok]
db 20*20*20*512 - ($ - $$) dup 0

- make a bootsector [Ok]
org 0x7C00
db 510 - ($ - $$) dup 0
dw 0xAA55

- make a fu*&^%g data on the disk, but at arbitrary address:
org 0x1000
align 512
main:
jmp $


align 512
main_end:

doesnt work! How can i put my data after org 7c00 and still have $ - $$ work?
