Pre-allocated Memory

請問各位Intel system address map中的Pre-allocated Memory是什麼意思呢?

Viods of physical addresses that are not accessible as general system memory and reside within system memory address rang( <TOSM) are created for SMM-mode and legacy VGA graphics compatibility. For VGA graphis compatibility, pre-allocated memory is only required in non-local memory configuration. It is the responsibility of BIOS to properly initialize these regions.

這段有看沒有懂@_@

    為 SMM-mode and legacy VGA graphics compatibility, 空出實体位址

    意指, pre-allocated memory 是不能像 一般的 system memory 被 OS 存取, 且 其範圍在 system memory 中

    剩下兩句請自行翻譯

    另外, 就 VGA 的 pre-allocated memory

    (1) Operating System 看不到 pre-allocated memory

    (2) pre-allocated memory 是保留給 VGA 用的

    (3) pre-allocated memory 的 配置, 是 BIOS 的責任
