trying to install on basic p4, which will run 8.04, it stops and tells me

" your cpu appears to be lacking expected security protection " blah blah blah

any simple ideas ??

Thank You

This is a new security check in 10.04. It sees your CPU as one that uses the NX Bit setting. Check your BIOS to see if you can enable it.


NX stands for "No Execute" and is a setting used in newer AMD CPUs that prevents code from running in data-only memory pages, which is a common technique used in buffer-overflow attacks.

Intel's version is XD , or "eXecute Disable".

If your BIOS does not have the option to enable NX (or XD), then check to see if you have a BIOS update available. If not, or if that doesn't fix the problem, you will have to contact the BIOS manufacturer.
