The 328 without a P has a different signature from the 328 with a P - this will be causing the failure - need to edit boards.txt I think.

I've edited boards.txt, and when programming, I use the -F feature to override the signature check. The important pins are as follows:
MOSI (D11)        pin 15
MISO (D12)        pin 16
SCK (D13)        pin 17
Reset        pin 29
+5V        pin 4, 6, 18
GND        pin 3, 5, 21

try the optiloader, I think it supports atmega328

I have tried several ways to burn bootloader, and unsuccessful with all of them until I tried optiloader and it worked on my first try.
