chdir on linux does not work

[Noprianto <opennopri@xxxxxxxxx>]

Dear All,

Anyone can tell me why this chdir code doesnot work on
linux ?

-> from what i read, chdir is system call number 12


section .text
        global _start

_start:
        mov eax, 12
        mov ebx, dir
        int 80h


        mov eax, 1
        mov ebx, 0
        int 80h



section .data
dir:    db      '/bin'



Thanks,
Pri
