字段 | 类型与说明
dwOemID | Long，System processor used. In Windows 95, this value is always set to zero (PROCESSOR_ARCHITECTURE_INTEL). In Windows NT, this value may be one of the following : PROCESSOR_ARCHITECTURE_INTEL, PROCESSOR_ARCHITECTURE_MIPS, PROCESSOR_ARCHITECTURE_ALPHA, PROCESSOR_ARCHITECTURE_PPC
dwPageSize | Long，Page size used. Also specifies the granularity of page protection and commitment.
lpMinimumApplicationAddress | Long，Contains the lowest memory address that applications and dynamic link libraries (DLLs) can access.
lpMaximumApplicationAddress | Long，Contains the highest memory address that applications and DLLs can access.
dwActiveProcessorMask | Long，Contains a mask representing the set of processors available on the system. Processor zero is indicated by bit zero being set.
dwNumberOrfProcessors | Long，The number of processors in this system.
dwProcessorType | Long，Obsolete, but maintained for backward compatibility. Can be one of the following values: PROCESSOR_INTEL_386, PROCESSOR_INTEL_486, PROCESSOR_INTEL_PENTIUM. The following are valid on Windows NT systems only: PROCESSOR_MIPS_R4000, PROCESSOR_ALPHA_21046
dwAllocationGranularity | Long，Contains the allocation granularity used to allocate memory. This value is usually set to 64K.
wProcessorLevel | Integer，Specifies the processor level. This value depends on the PROCESSOR_ARCHITECTURE_* value in the dwOemID field. For PROCESSOR_ARCHITECTURE_INTEL, the valid values are currently: 3 for a 386 CPU, 4 for a 486 CPU, and 5 for a Pentium.
wProcessorRevision | Integer，Specifies the processor revision. This value depends on the PROCESSOR_ARCHITECTURE_* value in the dwOemID field.
