I got a couple of Dorkboard kits from Surplus Gizmos a couple of weeks  
ago and the basic problem is that they hadn't programmed the  
bootloader into the 168 chips that they are selling.  According to  
Don, they said they would do it but apparently haven't.  Probably the  
simplest fix is to drop by the DorkbotPDX meeting on Monday evening  
and ask Don to put the bootloader on your chip.  That is what I did at  
the last meeting.
After the bootloader is put on the chip, then the Arduino software can  
be used as an IDE to create C/C++ programs and download them via the 5  
pin header with the appropriate USB to TTL serial adapter (I use the  
Benito that Don makes and gives out at the periodic Arduino Cult  
inductions).
