IA32 Logical Flat or Cluster Mode Override Enable (LogFlatClustOvrEn):

0 : IA32 Logical Flat or Cluster Mode bit is locked as Read only bit. 
1 : IA32 Logical Flat or Cluster Mode bit may be written by SW, values 

written by xTPR update are ignored. 
For one time override of the IA-32 Logical Flat or Cluster Mode value, return 

this bit to its default state after the bit is changed. Leaving this bit as “1” will 

prevent automatic update of the filter.

IA32 Logical Flat or Cluster Mode (LogFltClustMod):

Set by BIOS to indicate if the OS is running logical flat or logical cluster 

mode. This bit can also be updated by IntPrioUpd messages. 
This bit reflects the setup of the filter at any given time. 
0 - flat, 
1 - cluster.
