ANSWER
If you are creating a code banking application...
（如果你创建了代码分页）
L51_BANK.OBJ is the object file that is generated by the assembler from the L51_BANK.A51 object module. Make sure that you have properly configured the L51_BANK.A51 file and assembled it for your project. If you use µVision, make sure that L51_BANK.A51 is included in your project.
(L51_BANK.OBJ是通过L51_BANK.A51工程模块 汇编创建的工程文件，确保你当前配置好了L51_BANK.A51文件并为你的工程编译，如果使用µVision(keil4)确保L51_BANK.A51文件包含在你的工程里 )
看具体操作： 复制keil 安装目录下的 C:\KEIL4\C51\LIB\L51_BANK.OBJ到你建的工程里面并像添加。c或。h一样加入工程source group 中 ，编译一下加好了。。
If you are NOT creating a code banking application...
Open the Project Options dialog in µVision and uncheck the Code Banking checkbox at the bottom left of the Target tab.
(如果没有创建代码分页或分块，打开工程选项对话框，取消Code Banking勾选项)
操作如下：
projiect——>option for target ——>取消左下角的code banking勾选项即可
