644p bootloader ?

Im using the guide from http://www.gammon.com.au/forum/?id=11635 to attempt to burn a different boot loader onto the 644p so it will work with the latest arduino Ide.Im using a atmega 328 as the programmer and the 644p as the slave.The error im getting is

Atmega chip programmer.
Written by Nick Gammon.
Entered programming mode OK.
Signature = 0x1E 0x96 0x0A 
Processor = ATmega644P
Flash memory size = 65536 bytes.
LFuse = 0xFF 
HFuse = 0xDC 
EFuse = 0xFD 
Lock byte = 0xCF 
Clock calibration = 0x82 
No bootloader support for this device.
Type 'C' when ready to continue with another chip ...

Ideas please ?

There is no official Arduino using the 644P chip so I don’t think Nick’s code includes a bootloader for it. You should be able to get one from the Sanguino folks. Here are some instructions for burning the bootloader:
