In a bootloader, the second last line is :
TIMES 510-($-$$) db 0
Now, will this command also do the same :
db 510-($-$$) DUP (0)
If not why?
I know what
TIMES does, but its not mentioned in my x86 book by Mazidi (Pearson Publication). Any idea why?
And what is the meaning of the
$ sign exactly? Different sites have different information about
And is the line
TIMES 510-($-$$) db 0 absolutely necessary even if my bootloader code is of 512 bytes in size?
So can anyone help me with these questions?
