correct baud-rate for avrdude to programme ATMEGA8-16PU

Hi Arduino, I am lost in loading bootloader for Arduino Single Sided on ATMEGA8-16PU. Here is my problem. 1- I made the Arduino Single Sided V3 from this page http://www.arduino.cc/en/Main/ArduinoBoardSerialSingleSided3. 2- Placed ATMEGA8-16PU in the board and attached it to the Parallel Programmer described here http://www.arduino.cc/en/Hacking/ParallelProgrammer and attached external 9V battery. 3- Accessed the controller using avrdude using command line and it returned correct signature 0x1e9307. 4- I executed this command "avrdude -p atmega8 -c dapa -P lpt1 -U lock:w:0xff:m" it worked well. Everything was fine till this point and controller returning correct signature. 5- Then this "avrdude -p atmega8 -c dapa -P lpt1 -U hfuse:w:0xca:m -U lfuse:w:0xdf:m" and suddenly after execution of this command controller was returning wrong signature 0x000012.

What is wrong? i cannot go further? why it is returning the wrong signature. But i noticed something odd, controller was not returning 0xffffff it means it is not bricked, its alive and hence returning signature whatever it is. May be the default baud-rate of programmer is not matching anymore with the baud-rate change in controller for different clock source. What should i do ?

Make absolutely certain the crystal and capacitor connections are good.

returning wrong signature 0x000012

Was "0x000012" the signature value returned? Or was the value "0x000102"?
