Hardware abstraction layer and the kernel or the machine type do not match ( usually when single - processor and multiprocessor configuration files are mixed on the same system ) 硬件抽象层与内核或机器类型不匹配（通常发生在单处理器和多处理器配置文件混合在同一系统的情况下） 。
If you have a custom hardware abstraction layer ( hal ) file supplied by your computer manufacturer , before beginning setup , locate the floppy disk or other medium containing the file 如果计算机制造商提供了自定义的硬件抽象层（ hal ）文件，那么在运行安装程序之前，找到包含该文件的软盘或其他介质。
If you have specialized hardware requiring a custom hardware abstraction layer ( hal ) file supplied by your computer manufacturer , see " using a custom hardware abstraction layer ( hal ) file " earlier in this chapter 如果有特定的硬件需要计算机制造商提供自定义的硬件抽象层（ hal ）文件，请参阅本章前面的“使用自定义硬件抽象层（ hal ）文件” 。
If you have a mass storage controller that requires a driver supplied by the manufacturer , or if you have a custom hardware abstraction layer ( hal ) file supplied by the manufacturer , you will need to provide the appropriate driver file or hal file during setup . 如果有需要制造商提供驱动程序的海量存储控制器，或者有制造商提供的自定义硬件抽象层（ hal ）文件，那么在安装过程中需要提供这个相应的驱动程序文件或hal文件。
While the key of embedded system software is embedded operation system ; one of the main works in os application is to write the hal ( hardware abstraction layer ) code . two open source code embedded operation system - uc / os and embedded linux were analyzed in this paper 文中作者以broadcom主板为硬件平台(基于motorola通信处理芯片mpc850 )对两种公开源代码的操作系统uc os和嵌入式linux进行了研究与应用设计，其中的关键步骤是编写硬件抽象层接口程序。
Second , porting ecos system is the cornerstone of ecos system , the job is according to target board programme that bottom hal ( hardware abstraction layer ) porting code and certain driver codes supportting devices of target board , then configures , complices , links and borns an ecos library file 本人还参与完成的一个基于ecos的voip终端的设计和实现。该终端是基于飞思卡尔公司的mcf5235evb评估板和本文成功移植的ecos嵌入式操作系统,并在其上移植sip等相关的应用协议栈。
