WinCE5.0 SMDK2410 BSP在GEC2410开发板上的移植(13)-HIVE注册表实现

之前我们已经实现了Multi-Bin,CE已经可以正常启动运行.但是我们修改的系统设置在重启后就又恢复成初始状态.那是因为我们的注册表是基于RAM的,要实现注册表永久保存就需要实现HIVE注册表.
我们把注册表保存在Nand flash的FAT分区中.
在注册表中,HIVE BOOT SECTION和END HIVE BOOT SECTION直接的注册表内存就保存在HIVE中.
1.添加HIVE组件
Hive-based Registry
2.修改注册表
之前讲Multi-Bin时,HIVE注册表已经实现了,和HIVE相关的注册表设置之前都已经提及了.我们要保存的注册表内容都在system.hv中.
; @CESYSGEN IF FILESYS_FSREGHIVE
; HIVE BOOT SECTION

[HKEY_LOCAL_MACHINE/init/BootVars]
"SystemHive"="Documents and Settings//system.hv"
"ProfileDir"="Documents and Settings"
"Flags"=dword:3 ;等同于 "Start DevMgr"=dword:1,讲注册表保存到ROM中
"RegistryFlags"=dword:1 ;自动刷新system.hv,每次修改设置就自动保存注册表
; END HIVE BOOT SECTION
; @CESYSGEN ENDIF FILESYS_FSREGHIVE

还有个重要的设置就是我们的存储介质,设置MountAsBootable说明注册表保存在该存储设备中,系统启动时就从这里读取注册表内容
[HKEY_LOCAL_MACHINE/System/StorageManager/Profiles/MSFlash/FATFS]
"MountAsROM"=dword:0
"MountHidden"=dword:0
"MountAsBootable"=dword:1
"Flags"=dword:00000014 ;FATFS_FORCE_WRITETHROUGH | FATFS_DISABLE_AUTOSCAN
"EnableWriteBack"=dword:1
"CheckForFormat"=dword:1

完整注册表如下:(讲Multi-Bin已列举过)
