CPUID must be issued with each parameter in sequence to get the entire 48-byte ASCII processor brand string. [149] It is necessary to check whether the feature is present in the CPU by issuing CPUID with EAX = 80000000h first and checking if the returned value is not less than 80000004h.
Tunnel Creek" CPU with an Altera Field Programmable Gate Array (FPGA) CPU core supports IA-32 architecture, MMX, SSE, SSE2, SSE3, SSSE3, Enhanced Intel SpeedStep Technology (EIST), Hyper-Threading, Intel VT-x; Package size: 37.5 mm × 37.5 mm; Steppings: B0; TDP without FPGA. Total package TDP depends on functions included in FPGA. Max. TDP 7 W.
A member of the Intel Enthusiast Team has stated in a series of posts on enthusiast site Tom's Hardware that while the Atom D2700 (Cedarview) was designed with Intel 64 support, due to a "limitation of the board" Intel had pulled their previously available 64-bit drivers for Windows 7 and would not provide any further 64-bit support.

(On the IBM PC platform, direct software access to the IBM BIOS routines is available only in real mode, since BIOS is written for real mode. However, this is not a property of the x86 CPU but of the IBM BIOS design.) In order to use more than 64 KB of memory, the segment registers must be used.
All Sandy Bridge processors with one, two, or four cores report the same CPUID model 0206A7h [18] and are closely related. The stepping number cannot be seen from the CPUID but only from the PCI configuration space. The later Sandy Bridge-E processors with up to eight cores and no graphics are using CPUIDs 0206D6h and 0206D7h. [19]
Windows CE, later known as Windows Embedded CE and Windows Embedded Compact, is a discontinued operating system developed by Microsoft for mobile and embedded devices. It was part of the Windows Embedded family [12] and served as the software foundation of several products including the Handheld PC, Pocket PC, Auto PC, Windows Mobile, Windows Phone 7 and others.
Threads have their own thread ID, program counter (PC), a register set, and a stack, but share code, heap data, and other resources with other threads of the same process. [87] [88] Thus, there is less overhead to create a thread than a new process. [89] On single-CPU systems, concurrency is switching between processes.
Windows can be configured to use free space on any available drives for page files. It is required, however, for the boot partition (i.e., the drive containing the Windows directory) to have a page file on it if the system is configured to write either kernel or full memory dumps after a Blue Screen of Death. Windows uses the paging file as ...
