The flash7800 script is a modified version of the script we use to flash 
boards at the factory.  You may want to look over and edit the script before 
running it in case some of the steps are/aren't needed.  For instance, you 
may need to uncomment and tweak the first line if the nand flash drivers 
aren't loaded yet on your board.  If you suspect you still have a working 
root filesystem you may also want to comment out the parts dealing with 
untarring the root filesystem so as to save a lot of time.

The steps of the script are:

1. Load the module for the nand flash.
(Commented out because this is not usually necessary on a working board)

2. Copy the MBR to the flash

3. Copy the kernel to the first partition on the flash

4. Copy the initial ramdisk (initrd) to the second partition on the flash

5. Erase the third partition of the flash
   Create a temporary directory
   Mount the third partition of the flash on that directory (as yaffs)
   Unpack the sarge tarball
   run an MD5sum on everything to make sure everything unpacked ok
   unmount the flash

If any of the commands has an error, the script will terminate.
