¿Es posible direccionar mas de 0FFFFh bytes en modo real, aunque hablemos de un i386 u otro procesador con arquitectura x86?

I believe "...but you won't be able to get the [eax] memory cell." is not true. My understanding is that in real mode, if the value of eax is less than or equal to 0x0000FFFF, then [eax] is a perfectly valid access. Larger values of eax will generate a protection fault when you attempt to access [eax] (though notably [ax] need not generate a protection fault if [eax] would)

Gracias...
