标题：wince添加SD卡的支持
摘要：
备注：Windows CE 5.0

=============================================================
需要添加的驱动和组件如下：
① Device Drivers | SDIO | SD Memory
② Device Drivers | SDIO | SDIO Host | Samsung 2410 SDIO Host
③ Core OS | Windows CE devices | File Systems and Data Store | Storage Manager | FAT File System
这里添加FAT文件系统，以便以后对SD卡进行读写。
和SD卡有关的注册表内容如下：

; setting for SD bus driver to load driver
[HKEY_LOCAL_MACHINE/Drivers/SDCARD/HostControllers/SDSC]
"Dll"="SDCSDCard.dll"

这里将SD卡盘符的名字修改为SDCard：
[HKEY_LOCAL_MACHINE/System/StorageManager/Profiles/SDMemory]
"Folder"="SDCard" ; notears
先Copy Files，然后Sysgen系统，重新烧写NK，启动系统，插上SD卡测试了一下，如图：
