Text: Allows you to determine whether to limit CPUID maximum value. Set this to enabled for legacy operating systems such as Linux or Unix.
Found this in the BIOS of a Gigabyte Z97X-UD3H mobo.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I get how this could be interpreted as offensive, but I think it is just poorly worded.
This option is for if you are using a legacy version of Linux such as 2.6.x (eg, on an old RedHat distro that your business systems are designed to be run on).
This enables a compatibility mode so the old kernels don't complain.
Given the usual quality of BIOS/UEFI option descriptions it's remarkably close to being sensible. I would've expected something like "enables limiting CPUID maximum value".
Set to "Enable" to enable the feature.
It's really just that Linux is the only thing where it's possible to run an envient version on modern hardware
