Re: SD card boot sector location

2006-02-21 by theothervmax

Hi guys,
there is something strange with this thread started by me several 
months ago. It's been active for a few days and then happy ended ;-)
Now I see that this thread appears again but not with the context of 
my (already solved) problem. Now it's just about an article 
published by Circuit Cellar and nothing more...
Thank you anyway.
Regards,
  Max
