is selected, the BIOS forces the XD feature flag to always return to 0.

improve the load-to-use latency. Set to enable or disable.
Adjacent Cache Line Prefetch
The Adjacent Cache-Line Prefetch mechanism, like automatic hardware
prefetch, operates without programmer intervention. When enabled through the
BIOS, two 64- byte cache lines are fetched into a 128-byte sector, regardless of
whether the additional cache line has been requested or not. Set to enable or
disable.
