First off, can I use the amd64 kernel with a Sempron processor? I am
not sure if it has support for 64 bit programs. If not, of the other
If you can do a 'cat /proc/cpuinfo" you should see a "lm" entry on the
Flags line. If that is there, then the processor will be able to do
amd-64. If not, it won't.
If it can't do the 64-bit, then the best option is a k7 kernel for
your processor.
Nope. Here is the output of 'cat /proc/cpuinfo'
