Split Lock Operations

Common Options : Enabled, Disabled

Quick Review

This is a debug feature specific to the Intel Pentium 4 and the Intel Pentium 4 Xeon processors. It allows you to prevent the processor from issuing split lock cycles to the processor bus if such operations cause problems.

Split lock cycles can potentially cause problems in certain situations. For example, the Split Lock Cycles bug in the Intel 82860 MCH.

Usually, it is recommended that you leave Split Lock Operation at its default setting of Enabled. This allows the processor to issue split lock cycles to the processor bus. However, if you are using a motherboard based on the Intel 82860 chipset, you should disable this feature.

There may be other situations where split lock cycles can cause problems. If your system hangs or crashes for no apparent reason, you can try disabling this feature and see if it solves the problem. Otherwise, leave it enabled.
