本标准假设读者熟悉传统的INT 13h接口，即BIOS的使用 设备参数表，以及大容量存储设备的基本操作。本标准详细描述了 BIOS功能和数据结构，用作抽象层，以允许更高级别的应用程序 以独立于接口和命令集的方式访问大容量存储设备。为了遵守这一点 标准的高级软件应使用本文所述的数据结构调用INT函数，以及 系统固件应提供本文所述的INT功能和数据结构。

This standard assumes that the reader is familiar with the conventional INT 13h interface, the usage of the BIOS Device Parameter Table, and the basic operation of mass storage devices. This standard describes in detail BIOS functions and data structures that are used as an abstraction layer to allow higher-level applications to access mass storage devices in an interface and command-set independent manner. To comply with this standard, higher-level software shall call the INT functions using the data structures described herein, and system firmware shall provide the INT functions and data structures described herein.
