install the NET MF onto a ARM7 chip(AT91SAM7x256)

[color=#008000;]Hi researchers;[/color]

I have two questions:

First:

I would like to install arduino bootloader on a AT91SAM7x256 chip.How can I do this?

And Second question:

how do I design a new bootloader file for a new hardware platform with this config:

1. Chip : AT91SAM7x512

2. I2C,SPI and 8 Digital Input/Output bus

My design hardware picture is attached to this message.

I'm confused, you talk about installing the arduino bootloader.... on the netduino forums?
