Questions tagged [i386]

Use i386 tag for questions related to 32-bit implementation of x86 ISA

The 32-bit version of x86 instruction set architecture (ISA) is now called i386, after Intel's first 32-bit processor, the 80386, which is also known as i386.

For general x86 ISA questions, which are not specific to 32/64 bits, use tag instead.
