I. Hive registry function
[HKEY_LOCAL_MACHINE/init/bootvars]
"Systemhive" = "Documents and Settings // system. HV"
"Profiledir" = "Documents and Settings"
"Defaultuser" = "default"
"Start devmgr" = DWORD: 1
"Flags" = DWORD: 3
"Registryflags" = DWORD: 1
 
Note:
Systemhiv
Path and file name of hive files in the system
 
Profiledir
Path for saving the user configuration file
 
Defaultuser
User hive file loaded by default
 
Start devmgr
Load Device Manager at startup
 
Flags
This value replaces start devmgr and provides more precise control on the premise of including the start devmgr function.
Flag bit Setting Description
0x00000001 starts Storage Manager in phase one of startup for hive-based registry
(To implement hive, load the Storage Manager at startup)
0x00000002 starts Device Manager in phase one of startup for hive-based registry
(To implement hive, load the Device Manager at startup)
0x00000004 starts Storage Manager in phase one of startup for registry in external Rom, such as binfs
(To register extended Rom such as binfs, load the Storage Manager at startup)
0x00000008 starts Device Manager in phase one of startup for registry in external Rom, such as binfs
(To register extended Rom such as binfs, load the Device Manager at startup)

 
Registryflags
The regflushkey function is automatically called when the regclosekey function is called to automatically save the registry.
 
 
The Device Manager loads all device drivers under HKEY_LOCAL_MACHINE/Drivers/builtin.
 
 
 
Ii. Storage Management
[HKEY_LOCAL_MACHINE/system/storagemanager/profiles]
"Automount" = DWORD: 1
"Autopart" = DWORD: 0
"AutoFormat" = DWORD: 0
"Mountflags" = DWORD: 0
"Defaultfilesystem" = "fatfs"
"Partitiondriver" = "mspart. dll"
"Folder" = "mounted volume"
 
 
[HKEY_LOCAL_MACHINE/system/storagemanager/profiles/smflash]
"Defaultfilesystem" = "binfs"
"Autopart" = DWORD: 1
"Automount" = DWORD: 1
"Partitiondriver" = "mspart. dll"
"Name" = "Microsoft flash disk"
"Folder" = "residentflash"
"Bootphase" = DWORD: 0
"AutoFormat" = DWORD: 1
 
[HKEY_LOCAL_MACHINE/system/storagemanager/profiles/hdprofile]
"Name" = "IDE Hard Disk Drive"
"Folder" = "Hard Disk"
"Automount" = DWORD: 1
"Defaultfilesystem" = "exfat"
"Partitiondriver" = "mspart. dll"
 
Definition of [HKEY_LOCAL_MACHINE/system/storagemanager/profiles/hdprofile/fatfs] fatfs
"Enablecachewarm" = DWORD: 0
 
[HKEY_LOCAL_MACHINE/system/storagemanager/profiles/hdprofile/partitiontable]
"07" = "" (This value indicates that NTFS-type partitions do not enhance any file system)
 
[HKEY_LOCAL_MACHINE/system/storagemanager/profiles/sdmmc]
"Name" = "sd mmc device"
"Folder" = "SD card"
 
The branch can be defined as follows:
Flag description
"AutoFormat" whether to automatically format (1-Yes, 0-No)
"Automount": automatic mounting (1-Yes, 0-No)
"Autopart": automatic partitioning (1-Yes, 0-No)
"Defaultfilesystem" identifies unknown Partition Table IDS as partition types by default, such as binfs
"Folder" Mount directory name
"Mountflags" has been abolished since Win CE 5.0. It is used to identify the partition Mount mode.
"Name" storeinfo (Storage Manager) struct. szstorename member variable value
"Partitiondriver": Default loaded partition driver

 
 
Iii. File System
1. autoload settings
[HKEY_LOCAL_MACHINE/system/storagemanager/autoload/relfsd]
"DLL" = "relfsd. dll"
"Paging" = DWORD: 1
"Loadflags" = DWORD: 1
Value: type description
Loadflags: REG_DWORD controls how to load the file system.
1-The file system needs to be automatically loaded at the 0 or 1 phase of startup.
2-asynchronous loading in another thread. It is only supported in Phase 2 of startup (default value)
Bootphase: REG_DWORD control is used to verify the file system loading.
0-load before local initialization.
1-load after local initialization, before the registry function is loaded.
2-after the registry function is loaded.
DLL: REG_SZ: fsd dll file
Order: REG_DWORD specifies the loading sequence. The smaller the value, the more loaded.

2. File System settings
[HKEY_LOCAL_MACHINE/system/storagemanager/fatfs]; general definition
"Friendlyname" = "tfat filesystem"
"Flags" = DWORD: 00000014
"DLL" = "exfat. dll"
"Cachesize" = DWORD: 0
 
[HKEY_LOCAL_MACHINE/system/storagemanager/profiles/smflash/fatfs]; detailed definition
"Flags" = DWORD: 14
"Formattfat" = DWORD: 1
"Mountasbootable" = DWORD: 1
"Checkforformat" = DWORD: 1
 
 
Registry Value: type description
Buffersize: the buffer size of REG_DWORD.
The default value is 64 for tfat 32 for fat.
Cachesize: the disk cache size of REG_DWORD is in the unit of slices. If it is set to 0, the best cache is automatically used.
CodePage: REG_DWORD overrides cp_oemcp in all character conversions.
DLL: REG_SZ DLL file name.
Enablecache: whether to enable cache in REG_DWORD
0-Disable 1-enable
Enablecachewarm: REG_DWORD enables pre-warming of the cache.
Flags: REG_DWORD can be found in the table below.
Formattfat: REG_DWORD format to tfat
Friendlyname: REG_SZ specifies a friendly name for the file system.
Mountlabel: REG_DWORD volume name
Paging: REG_DWORD pagination 0-Disable 1-enable.
Util: REG_SZ specifies the DLL name of utility to do format and scan

 
Checkforformat
For Flash Media drivers (FMD), setting this flag will call ioctl_hal_query_format_partition IOCTL
 
 
Flag description
"Mountflags" abolished since Win CE 5.0
"Mounthidden" Hide mounting. 1-Enable. Replace "mountflags" = DWORD: 1
Whether "mountasbootable" includes the registry. The first mounted partition storage hive registry. 1-Enabled
Replace "mountflags" = DWORD: 2
"Mountasroot" is mounted as the root file system. 1-Enable. Replace "mountflags" = DWORD: 4

Fatfs_disable_autoformat 0x00000040 disable automatic formatting of unformatted partitions.
Fatfs_wfws_nowritethru 0x00010000 disables write through on the writefilewithseek function. improves memory-mapped file performance.

"Flags" = DWORD: 3
"Registryflags" = DWORD: 1
 
3. In the each driver that is loaded during the first phase of startup
[Add HKEY_LOCAL_MACHINE/Drivers/related item (this indicates that the driver is loaded only once)
"Flags" = DWORD: 1000
 
4,
[HKEY_LOCAL_MACHINE/system/storagemanager/profiles/<profilename>/<filesystemname>]

Add
"Mountasbootable" = DWORD: 1
