FreeBSD/amd64 Failed installworld btxlsd

In my last build of FreeBSD/amd64, installworld failed with the following error:
btxld:No such file or directory

It was a little cryptic, specially because it was a fresh install, but after a little internet search I found a possible cause/solution for the issue. The date/time was out of sync...and that was indeed the cause!

You can check the date/time by simply running this:
# date

To sync it I ran:
# adjkerntz -i

Then I re-installed world and everything went fine.

FreeBSD and Intel Core 2 Quad

This was a very silly mistake but since I always ran FreeBSD on Pentium machines then I always installed the i386 version; however, if you have an Intel Core 2 Quad CPU don't do that!!!

Intel Core 2 Quad is a 64-bit architecture and in order to take advantage of the four CPUs then you must install FreeBSD/amd64! You also need to have SMP enabled in the Kernel (which is already a standard in all the latest releases).

For more info, please read the FreeBSD hardware requirements page.
