Can’t find L2 cacahe

Could not find L2 cache in the Registry. Looked under: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControllerSet\Control\SessionManager\Memory_Management

Did I look in the wrong place? Why isn?t it there? How is L2 cache created? What should I do?

CPU Type Intel Pentium II, 400 MHz (4 x 100)
