The DS2 and DS3 registers (which are specific to the NEC V55) act similar to regular x86 real mode segment registers except that they are left-shifted by 8 rather than 4, enabling access to 16MB of memory. Block transfer instructions, such as MOVBKW, can access the 16MB memory space by simultaneously prefixing with DS2 and DS3.
Norton Guides manual and disks. Norton Guides were a product family sold by Peter Norton Computing.The guides were written in 1985 by Warren Woodford for the x86 Assembly Language, C, BASIC, and Forth languages and made available to DOS users via a terminate-and-stay-resident (TSR) program that integrated with programming language editors on IBM PC type computers.
The x86 instruction set refers to the set of instructions that x86-compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor. The x86 instruction set has been extended several times, introducing wider registers and datatypes as well as new ...

Bit manipulation instructions sets (BMI sets) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD. The purpose of these instruction sets is to improve the speed of bit manipulation. All the instructions in these sets are non-SIMD and operate only on general-purpose registers.
BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
A Universal Atomic 4, installed in a C&C 29 Mark 1 sailboat. The Universal Atomic 4 is a four-cylinder, gasoline engine produced by the Universal Motor Company between 1949 [1] and 1984 for use as auxiliary power on sailboats. [2] Both 18 horsepower (13 kW) and 30 horsepower (22 kW) versions of the engine were produced. [3]
3DNow! is a deprecated extension to the x86 instruction set developed by Advanced Micro Devices (AMD). It adds single instruction multiple data (SIMD) instructions to the base x86 instruction set, enabling it to perform vector processing of floating-point vector operations using vector registers.
