  2. x86 instruction listings - Wikipedia

    en.wikipedia.org/wiki/X86_instruction_listings

    8086/8088 datasheet documents only base 10 version of the AAD instruction (opcode 0xD5 0x0A), but any other base will work. Later Intel's documentation has the generic form too. NEC V20 and V30 (and possibly other NEC V-series CPUs) always use base 10, and ignore the argument, causing a number of incompatibilities: 0xD5: AAM

  3. BIOS parameter block - Wikipedia

    en.wikipedia.org/wiki/BIOS_parameter_block

    In computing, the BIOS parameter block, often shortened to BPB, is a data structure in the volume boot record (VBR) describing the physical layout of a data storage volume. ...

  4. x86 - Wikipedia

    en.wikipedia.org/wiki/X86

    However, the continuous refinement of x86 microarchitectures, circuitry and semiconductor manufacturing would make it hard to replace x86 in many segments. AMD's 64-bit extension of x86 (which Intel eventually responded to with a compatible design) [12] and the scalability of x86 chips in the form of modern multi-core CPUs, is underlining x86 ...

  5. AMD - Wikipedia

    en.wikipedia.org/wiki/AMD

    In 1981, IBM created its PC, and wanted Intel's x86 processors, but only under the condition that Intel would also provide a second-source manufacturer for its patented x86 microprocessors. [14] Intel and AMD entered into a 10-year technology exchange agreement, first signed in October 1981 [48] [54] and formally executed in February 1982. [37]

  7. x86 Bit manipulation instruction set - Wikipedia

    en.wikipedia.org/wiki/X86_Bit_manipulation...

    AMD was the first to introduce the instructions that now form Intel's BMI1 as part of its ABM (Advanced Bit Manipulation) instruction set, then later added support for Intel's new BMI2 instructions. AMD today advertises the availability of these features via Intel's BMI1 and BMI2 cpuflags and instructs programmers to target them accordingly. [2]

  8. List of discontinued x86 instructions - Wikipedia

    en.wikipedia.org/wiki/List_of_discontinued_x86...

    AMD introduced TBM together with BMI1 in its Piledriver [27] line of processors; later AMD Jaguar and Zen-based processors do not support TBM. [28] No Intel processors (as of 2023) support TBM. The TBM instructions are all encoded using the XOP prefix. They are all available in 32-bit and 64-bit forms, selected with the XOP.W bit (0=32bit, 1 ...

  9. Program Files - Wikipedia

    en.wikipedia.org/wiki/Program_Files

    To be backwards compatible with the 8.3 limitations of the old File Allocation Table filenames, the names 'Program Files', 'Program Files (x86)' and 'Common Program Files' are shortened by the system to progra~N and common~N, where N is a digit, a sequence number that on a clean install will be 1 (or 1 and 2 when both 'Program Files' and ...
