Part of the BootLoader code i am trying to develop.

The below code is unable to jump the specified address. Address 0x9000
contains my code loaded from floppy. The code at that address has got
the display routine, which is not executed after the jmp instruction.

mov ax,0x0900
mov es,ax
mov bx,0000
jmp 0x0900:0000
or
jmp [es:bx]

Assembler : NASM on Linux
Platform : LINUX Mandrake 8.0 ( Kernel 2.4.22 )
CPU : AMD ATHLON x86

Please anybody can answer at the earliest, it will be helpful for me.
