The other, known as Memtest86+, is a development fork of the original MemTest86. Their on-screen appearance and functionality were almost identical until MemTest86 4.3 and Memtest86+ 5.0. [1] Version 5.0 of MemTest86 added a mouse-driven graphical user interface (GUI) and UEFI support; the latter was added by Memtest86+ from version 6.0.
EAX contains flags controlling operation of instruction. [a] After being loaded, the IWKey cannot be directly read from software, but is used for the key wrapping done by ENCODEKEY128/256 and checked by the Key Locker encode/decode instructions. LOADIWKEY is privileged and can run in Ring 0 only. AESKLE AES Key Locker instructions. ENCODEKEY128 ...
Memory diagnostic software programs (e.g., memtest86) are low-cost or free tools used to check for memory failures on a PC. They are usually in the form of a bootable software distribution on a floppy disk or CD-ROM. The diagnostic tools provide memory test patterns which are able to test all system memory in a computer.

Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
Instruction set extensions that have been added to the x86 instruction set in order to support hardware virtualization.These extensions provide instructions for entering and leaving a virtualized execution context and for loading virtual-machine control structures (VMCSs), which hold the state of the guest and host, along with fields which control processor behavior within the virtual machine.
The x86 instruction set has several times been extended with SIMD (Single instruction, multiple data) instruction set extensions.These extensions, starting from the MMX instruction set extension introduced with Pentium MMX in 1997, typically define sets of wide registers and instructions that subdivide these registers into fixed-size lanes and perform a computation for each lane in parallel.
In the x86 assembly language, the TEST instruction performs a bitwise AND on two operands. The flags SF, ZF, PF are modified while the result of the AND is discarded. The OF and CF flags are set to 0, while AF flag is undefined. There are 9 different opcodes for the TEST instruction depending on the type and size of the operands. It can compare ...
