DSS-1 firmware boot loader instructions

Put it on the root of the USB drive, along with the DSS1_USB.BIN file from the version of choice.

Boot into test mode, and you should be prompted to "Upgrade OS? (Y/N)".
After pressing 'yes', and again after the 'are you sure' query, the versions of OLD 
(currently in Flash) and NEW (on the USB drive) will be displayed.  One last "Continue?" is asked,
then the update happens.

The status displayed during the update indicates 'E' during the chip erase, 
followed by the page numbers '0' thru '7' during the programming.  
The cursor flashes on and off as progress is made within each page.
