S40334 is the Також, неприсутні сторінки використовуються в плоскій моделі пам'яті (де розмір сегмента зазвичай має розмір від 2 до 4 гігабайт, навіть якщо у комп'ютера немає стільки фізичної пам'яті) для маркування сторінок сегмента, в які операційна система не виділила пам'яті. Перші процесори 386DX мали помилку, яка іноді приводила до невірних результатів при роботі з 32-розрядними числами в таких програмах, як OS / 2 2.x, UNIX/386, або Windows у розширеному режимі. for a B0 stepping was 0x02, but according to Turley (see above), the B0 and B1 steppings report the same The 80386 added a three-stage instruction pipeline, extended the architecture from 16-bits to 32-bits, and added an on-chip memory management unit. PUSH, POP or memory reference instructions). In 1988, Intel introduced the 80386SX, most often referred to as the 386SX, a cut-down version of the 80386 with a 16-bit data bus mainly intended for lower-cost PCs aimed at the home, educational, and small-business markets, while the 386DX remained the high-end variant used in workstations, servers, and other demanding tasks. SMM), as well as different "sleep" modes to conserve battery power. either two bytes or ten bytes from memory to the coprocessor. Процесор випускався в корпусах PQFP-132 (такі процесори мали літеру «NG» на початку назви, наприклад, NG80386DX25) або в керамічному PGA-132 (такі процесори мали літеру «A» на початку назви, наприклад, A80386DX25). number on the top line as A1, A2, or B1. [12], Among the BSDs, FreeBSD's 5.x releases were the last to support the 386; support for the 386SX was cut with release 5.2,[25] while the remaining 386 support was removed with the 6.0 release in 2005. However, Intel subsequently used the "DX" suffix to refer to the floating-point capability of the 80486DX. В ранних процессорах x86 для организации точки останова было необходимо заменить первый байт команды на команду вызова отладочного прерывания (int 3), вызов прерывания возвращал управление отладчику, который возвращал исходное значение первого байта команды. Major new feature in the i386 CPU was 80386 protected mode - this mode fixed many shortcomings that existed in the 80286 processor and in the 80286 protected mode: If it says A80386-16ES, then it’s an engineering sample and the vendor is a cheapskate.

See the photographs, the Intel logo is clearly visible and the chips photographed are of the same batch as the ones you will receive. If none of these faults are recognized, the fault handler can assume this errata caused the GP fault [citation needed] The 386 was the first significant microprocessor to be single-sourced.
