That rocks! Thank you so much for that information. I hope it's 
reliable, as according to the output of that command my Emachine T3410 
is a 64 bit machine, which I was unaware of before.

It also has room for up to 8 GB of RAM via two 4 GB modules with a 64 
bit data path, and states that the maximum speed for the cpu is 3000 
mhz, but it is running at 2010 mhz currently, which is what my AMD 
Sempron 3400+ processor is rated for. It *is* reporting my cpu as being 
an AMD Athlon 64, in a Socket 940 connector however, so either the specs 
I've read about my machine are incorrect, or the BIOS is lying to me.

It lists Upgrade: Socket 754 also in the CPU information area, but I 
have no idea how one would go about upgrading the CPU Socket. I'm going 
to have to do some surfing today to try and verify this information. 
It's great that we can run a simple command line program to poll the 
BIOS in Linux, there is no way that I know of to get the same 
information without rebooting Windows and actually entering the BIOS setup.

Thanks again! Later, Ray Parrish
