Yet Another Bootloader Problem

Hi, Everyone!!!

I am Having trouble burning the bootloader into an Atmega168.
I built the parallel programmer and when I try to burn it I get this:

avrdude: verifying ...
avrdude: 1 bytes of lock verified
avrdude: reading input file "0x00"
avrdude: writing efuse (1 bytes):

Writing | bitbang_cmd(): [ 50 08 00 00 ] [ FF FF FF FF ]

avrdude done. Thank you.

I've checked the wiring of the programmer and it seems OK.
Also I'm using version 0011.

Thanks in advance for your help.
