Anyone have the Arduino Duemilanove Atmega328 16Mhz bootloader.hex

I'm having problems after original chip was damaged in a prototype board.
I tried all the bootloaders from the Arduino 0022 download, with the result I can't program sketches to the chip.

one bootloader on bootup flashes 6 times, then stops.
the other one flashes 3 times delay2 seconds, flashes 3 times and repeats.

The comms fault may be due to drivers not correctly installed.

Update: The hex files I was uploading to the chip, had erorors due to using a fualty pen drive.
When compared to the file you posted and a fresh download of Arduino confirms that was the problem.

I also found out the easiest was to program the boot loader is to use Arduino to auto select the file needed for the m328.

It solved a lot of problems with Arduino not finding the port to upload the sketches to the board.
