CPU Configuration

The items in this menu show the CPU-related information that the BIOS automatically
detects.
Ratio CMOS Setting [Auto]
Sets the ration between CPU core clock and the FSB frequency. Key in ratio numbers
directly.
If an invalid ratio is set in CMOS, then the actual and set values may differ.
C1E Support [Enabled]
Allows you to enable or disable C1E Support. Configuration options: [Disabled] [Enabled]
Hardware Prefetcher [Enabled]
Setting this item to [Enabled] allows the processor to fetch data and instructions from the
memory into the cache that are likely to be required in the near future. This reduces the
latency associated with memory reads. Configuration options: [Disabled] [Enabled]
Adjacent Cache Line Prefetch [Enabled]
When this item is set to [Enabled], the processor fetches the currently requested cache line,
as well as the subsequent cache line. This reduces the cache latency by making the next
cache line immediately available if the processor requires it as well. When set to [Disabled],
the processor fetches only the currently requested cache line. Configuration options:
[Disabled] [Enabled]
Max CPUID Value Limit [Disabled]
Setting this item to [Enabled] allows legacy operating systems to boot even without support
for CPUs with extended CPUID functions. Configuration options: [Disabled] [Enabled]

Virtualization Technology allows a platform to run multiple operating systems and applications
