LOADALL is the common name for two different, undocumented machine instructions of Intel 80286 and Intel 80386 processors, which allow access to areas of the internal processor state that are normally outside of the IA-32 API scope, like descriptor cache registers. The LOADALL for 286 processors is encoded 0Fh 05h, while the LOADALL for 386 processors is 0Fh 07h.

  • LOADALL is een ongedocumenteerde instructie van sommige microprocessors van Intel. LOADALL kan met één instructie alle registers van de processor laden. Interessant is dat ook de segmentdescriptors worden geladen, onafhankelijk van de segmentregisters, waardoor het onder andere mogelijk is in real mode het hele geheugen van de 80286 te benaderen. De instructie komt voor op de 80286 en de 80386, maar de werking is op die twee processors geheel anders. (nl)

  • LOADALL is the common name for two different, undocumented machine instructions of Intel 80286 and Intel 80386 processors, which allow access to areas of the internal processor state that are normally outside of the IA-32 API scope, like descriptor cache registers. The LOADALL for 286 processors is encoded 0Fh 05h, while the LOADALL for 386 processors is 0Fh 07h. Both variants – as the name implies – load all CPU internal registers in one operation. LOADALL had the unique ability to set up the visible part of the segment registers (selector) independently of their corresponding cached part, allowing the programmer to bring the CPU into states not otherwise allowed by the official programming model.
