   System Locked Pre-installation (SLP), also referred to as OEM Activation, is a product activation procedure for Microsoft Windows used by major OEMs of laptops and pre-built PCs wherein a Windows product key is added and locked to the machine's firmware before mass distribution. SLP product keys cannot be moved to other machines.

4. Physical Address Extension - Wikipedia

   en.wikipedia.org/wiki/Physical_Address_Extension

   However, "client" versions of 32-bit Windows (Windows XP SP2 and later, Windows Vista, Windows 7) limit physical address space to the first 4 GB for driver compatibility [16] even though these versions do run in PAE mode if NX support is enabled. Windows 8 and later releases will only run on processors which support PAE, in addition to NX and SSE2.

5. Intel MCS-51 - Wikipedia

   en.wikipedia.org/wiki/Intel_MCS-51

   Because IRAM, XRAM, and PMEM (read only) all have an address 0, C compilers for the 8051 architecture provide compiler-specific pragmas or other extensions to indicate where a particular piece of data should be stored (i.e. constants in PMEM or variables needing fast access in IRAM). Since data could be in one of three memory spaces, a ...

   MCU 8051 IDE has a built-in simulator not only for the MCU itself, but also LCD displays and simple LED outputs as well as button inputs. It supports two programming languages: C (using SDCC ) and assembly and runs on both Windows and Unix -based operating systems, such as FreeBSD and Linux .

7. Reset vector - Wikipedia

   en.wikipedia.org/wiki/Reset_vector

   The reset vector for the Intel 80286 processor is at physical address FFFFF0h (16 bytes below 16 MB). The value of the CS register at reset is F000h with the descriptor base set to FF0000h and the value of the IP register at reset is FFF0h to form the segmented address FF0000h:FFF0h, which maps to physical address FFFFF0h in real mode.

   The main editions also can take the form of one of the following special editions: N and KN editions The features in the N and KN Editions are the same as their equivalent full versions, but do not include Windows Media Player or other Windows Media-related technologies, such as Windows Media Center and Windows DVD Maker due to limitations set by the European Union and South Korea ...

9. Real mode - Wikipedia

   en.wikipedia.org/wiki/Real_mode

   Early versions of Microsoft Windows ran in real mode. Windows/386 made it possible to make some use of protected mode, and this was more fully realized in Windows 3.0, which could run in either real mode or make use of protected mode in the manner of Windows/386. Windows 3.0 actually had several modes: "real mode", "standard mode" and "386 ...
