分享请问如何读取笔记本电脑中的eeprom内容
大神指点下大致的方法就好，代码我自己写。网上搜索了下很多都是关于直接读取单片机的eeprom，我现在想在DOS或者window环境下编译程式去读取eeprom（bank0~bank7）里面的值。

把这段代码在win-tc里编译链接后提示的waitOBF ,waitIBE, loading ，clear_buffer, cursor, drawing_frame,loading_write 在这些模块里都是未定的符号......哪位大哥能指点一下呀？？谢谢

已经完成在DOS下读取Eeprom了，不过还是要谢谢老师。该程序是在Win-tc下编译，只能在部分机器中正确读取Eeprom，Eeprom挂在EC bank0~bank7下面的都可以，其中很多内容是DOS界面的修饰，以及一切用户功能的实现。

在Windows下的读写eeprom的工具软件肯定是通过特定的底层驱动（安装开发包时安装相应底层驱动(可能性较大)或Windows自带(可能性较小)）读写的。

现在不是用不用winIo的问题，问题是如何去读取。好比cmos是通过port70/71加offset去读取，那么eeprom呢？

被操作系统保护起来了，不能直接操作吧

使用WinIO.sys ？

编译的执行档在DOS执行的话是不受系统保护的，可以读取。就是开机按功能键进bios，再进dos优盘，然后执行exe可以避开window读取数据的。
