+where is the (optiboot) bootloader? Hex file is here:
+arduino-1.8.5/hardware/arduino/avr/bootloaders/optiboot_atmega328.hex
+
+ref: https://forum.arduino.cc/index.php?topic=125622.0
+
+example cmd:
+avrdude -c dragon_isp -P usb -p atmega328p -U flash:w:main.hex:i
+
+ref: https://forum.arduino.cc/index.php?topic=350727.0
+
+HOWEVER THAT IS WRONG. TRAP.
+
+EDIT: also need fuse bits programmed or else this will not work.
+(external crystal is used, in uno.)
+TRAP #2: you need an external crystal (16MHz) in the avrdragon, AFTER programming
+the fuse bits. You can solder wires to another uno board's crystal
+with the chip removed, if you don't have a 16MHz piece of quartz around.
+
+
+
+see https://learn.sparkfun.com/tutorials/installing-an-arduino-bootloader
+example there (note this is usbtiny)
+#avrdude -b 19200 -c dragon_isp -p m328p -v -e -U efuse:w:0x05:m -U hfuse:w:0xD6:m -U lfuse:w:0xFF:m
+EDIT: looks like sparkfun has incorrect information (or outdated).
+see arduino-1.8.5/hardware/arduino/avr/boards.txt
+for what arduino has for board values
+wrong entry (out of date):
+avrdude -b 19200 -c dragon_isp -p m328p -v -e -U efuse:w:0x05:m -U hfuse:w:0xD6:m -U lfuse:w:0xFF:m
+
+correct entry: (efuse must be 0xFD, as the reserved high bits must be set as 1's)
+avrdude -b 19200 -c dragon_isp -p m328p -v -e -U efuse:w:0xFD:m -U hfuse:w:0xDE:m -U lfuse:w:0xFF:m
+
+below are fuse bits. These should be used as well.
+avrdude -b 19200 -c dragon_isp -p m328p -v -e -U flash:w:hexfilename.hex -U lock:w:0x0F:m

+
+Get a good ziff socket for the dragon.
+
+Notice that the first header is VCC/GND breakout, the second is ICSP, and the
+third is directly tied to ZIFF socket.
+
+Also notice that JTAG and HV_PRG are not connected.
+
+My dragon was already setup for this, though some extra gnds were connected
+(e.g. I had vcc/gnd header's gnd connected to ICSP #6, and then another GND to
+pin 8 on the third breakout. But this picture has only ISP #6 to 8 (omitting
+the ground loop). Possibly either will work. I know mine works.
+
+
+
+You can watch the leds on the uno to see if it's working.
+
+if you do it correctly, LED 13 lights up with optiboot, then goes blank (or
+into sketch). If you have it failed, from a blank atmega328p, it will
+go solid, then after a short while start to blink.
+
+
+I have a dedicated Avrdragon for programming optiboot onto atmega328p.
+makes things easy. 
+
+
+WRONG CHIP:
+remember atmega328p-pu is the right chip
+atmega328-pu is wrong. 
+You can program atmega328-pu, by changing avrdude paramters, or using
+-F
+
+In this case, I changed atmega328p to atmega328 to reflect that I had the
+incorrect chip

+gotchas:
+
+* wrong atmega328 (need atmega328p-pu, not atmega328-pu) (though this can still be used)
+* need fuse bits set separate from programming hex (pickit w/pics on the other hand
+	handles this all in one)
+* need lock bits set
+* need 16MHz crystal when programming hex and lock bits (can use one from uno
+	board)
+
+quick guide:
+
+	set proper wiring on avr dragon (see image in pics)
+	set fuse bits
+avrdude -b 19200 -c dragon_isp -p m328p -v -e -U efuse:w:0xFD:m -U hfuse:w:0xDE:m -U lfuse:w:0xFF:m
+	add crystal, load hex, and program lock fuse
+avrdude -b 19200 -c dragon_isp -p m328p -v -e -U flash:w:hexfilename.hex -U lock:w:0x0F:m
+
+hexfilename.hex - the optiboot loader is included in
