Please check out the article Flash.Layout. It contains an example and a couple of explanations.
Information abput installing OpenWrt on the DG834.v3 can be found in the oldwiki under installing.openwrt.
If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
The Netgear firmware supports the Netgear recovery mode, which is documented on Netgear's website. Hold down the reset pin and power on, continuing to hold the pin in until the power and tick LEDs blink alternately.

How to connect to the Serial Port of this specific device:
BE WARNED that you should not run the VCC line to the VCC line on your TTL to RS232/USB adapter. Only wire up RX, TX and GND. The DG834G will happily draw power from the VCC line when its own power is not connected - 3.3V is enough for the LEDs to light up, 5V is enough for ADAM2 to start running! If you use an FTDI USB to TTL serial adapter, the power it consumes is enough to force the serial board to disconnect from the USB due to excessive current draw, which is incredibly inconvenient when trying to capture the bootloader messages (minicom quits when ttyUSB0 disappears).
