    Chew on this, The cpu is a AMD Sempron 140 made for a AM3 base. My 
base is a AM2+ and I goggled hard and found that the AM3 chips will 
mount fine in a AM2+ socket. It does.

    No joy. Called Gigibyte and they said I need a new bios called f-10 
which went available last week. I have not yet got the new bios or 
installed it. They said find an old AMC chip and see if it works. I will 
try to do that but no luck yet.

    I am about to say to heck with all this crap! It is just too hard to 
make your own computer. I need to buy the latest and best HP computer 
and load Linux on that, if even THAT is possible these days. For sure 
the warranty will be null and void :-)
