HIVE registry is useful and easy to use feature, to enable it, we need first add the HIVE registry feature from CATALOG
into the OSDesign file. then add registry as following listed.

The following is the setting in my platform using FLASH to store the registry.

There're some difference in every version.
1. in CE5.0 and later, DDK_GetWindowInfo can't be called in the flash driver.
if it's called, the system crashed in CE5.0 due to a data abort, it can't read the values in CE6.
2. The registry settings in CE5 are the same as CE4.2.
But there're some difference with CE6, Please look at the comment in the following paragraph.

; @CESYSGEN IF FILESYS_FSREGHIVE
; HIVE BOOT SECTION ; this line is mandatory for every verion, it indicates the start of HIVE registry setting.

[HKEY_LOCAL_MACHINE\init\BootVars]
"SystemHive"=" \\norflash\\Registry\\system.hv " ; in CE6, it's a full path, but in CE4.2 and 5.0, norflash is not needed.
"DefaultUser"="default"

?

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MSFlash]
"Name"="Ep93xx NOR Flash"
"Folder"="NORFlash" ; the value should be the same as the first word of "systemHive" in CE6
"AutoMount"=dword:1
"AutoPart"=dword:1
"AutoFormat"=dword:1

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MSFlash\FATFS]
;"MountFlags"=dword:2 ;uses this setting in CE4.2
"EnableCache"=dword:0
"MountBootable"=dword:1 ;uses this setting in CE6

; END HIVE BOOT SECTION ; this line is mandatory for every verion, it indicates the END of HIVE registry setting.

; @CESYSGEN ENDIF FILESYS_FSREGHIVE

NOTE

HIVE registry can work in NOR flash, but can't work in HARD DISK in WINCE6.0.

HIVE is called after hard disk driver is loaded while the file system is still not mounted, so the directory "HARD DISK" still not appears, as a result, HIVE creates a directory named "hard disk", and stores the registry to the directory.
but in nor flash, it does not occur.
