The vast majority of Intel server chips of the Xeon E3, Xeon E5, and Xeon E7 product lines support VT-d. The first—and least powerful—Xeon to support VT-d was the E5502 launched Q1'09 with two cores at 1.86 GHz on a 45 nm process. [ 2 ]
Protected mode may only be entered after the system software sets up one descriptor table and enables the Protection Enable (PE) bit in the control register 0 (CR0). [5] Protected mode was first added to the x86 architecture in 1982, [6] with the release of Intel's 80286 (286) processor, and later extended with the release of the 80386 (386) in ...
PAE was first introduced by Intel in the Pentium Pro, and later by AMD in the Athlon processor. [2] It defines a page table hierarchy of three levels (instead of two), with table entries of 64 bits each instead of 32, allowing these CPUs to directly access a physical address space larger than 4 gigabytes (2 32 bytes).
EPT support is found in Intel's Core i3, Core i5, Core i7 and Core i9 CPUs, among others. [6] It is also found in some newer VIA CPUs. EPT is required in order to launch a logical processor directly in real mode , a feature called "unrestricted guest" in Intel's jargon, and introduced in the Westmere microarchitecture .
The Pentium architecture added a number of enhancements to the virtual 8086 mode. These were however documented by Intel only starting with the subsequent P6 (microarchitecture) ; [ 6 ] their more recent formal name is Virtual-8086 Mode Extensions, abbreviated VME [ 7 ] (older documentation may use "Virtual 8086 mode enhancements" as the VME ...
Intel AMT is the set of management and security features built into vPro PCs that makes it easier for a sys-admin to monitor, maintain, secure, and service PCs. [11] Intel AMT (the management technology) is sometimes mistaken for being the same as Intel vPro (the PC "platform"), because AMT is one of the most visible technologies of an Intel vPro-based PC.
Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. [1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.
Intel responded by saying, "Intel does not put backdoors in its products, nor do our products give Intel control or access to computing systems without the explicit permission of the end user." [5] and "Intel does not and will not design backdoors for access into its products. Recent reports claiming otherwise are misinformed and blatantly false.
