I have some pretty basic questions about EEPROM programming on the 6811.  

I have the technical data book on the 'E2, but it talks about programming
the EEPROM as if you already have the ability to execute code on the 6811.
How do you actually go about programming the EEPROM?  Do you need to use
the bootloader to load a program that downloads code and programs it into
EEPROM?  If so, are there already some programs available as freeware to do
this?

What about hardware setup for the programming?  Obviously you need to
provide a serial connection to the SCI on the 6811.  Does it come up with a
particular set of com parameters?

Could I use the Miniboard and some downloading software for the PC to
program similar parts such as the 'A1 (only 512 bytes EEPROM)?  B.G. Micro
has the 68HC11A1FN for $5.95.  Seems like a good price.  Motorola's books
say it has EEPROM (I thought EEPROM parts had 811 in the number).

Thanks in advance.
