Detailed Explanation of SecondLevelDataCache
http://support.microsoft.com/kb/183063
"SecondLevelDataCache records the size of the processor cache, also known as
the secondary or L2 cache. If the value of this entry is 0, the system
attempts to retrieve the L2 cache size from the Hardware Abstraction Layer
(HAL) for the platform. If it fails, it uses a default L2 cache size of 256
KB. If the value of this entry is not 0, it uses this value as the L2 cache
size. This entry is designed as a secondary source of cache size information
for computers on which the HAL cannot detect the L2 cache."
