Re: Hive-Based Registry Settings

Did you wrap your platform changes with HIVE BOOT SECTION like you see in
common.reg?

If you are using drivers\builtin I am pretty sure that you need:

[HKEY_LOCAL_MACHINE\init\BootV­ars]
"Start DevMgr"=dword:1

Hello All,

I am working on ARM based processor. I want to add hive-based registry
to my platform. I want to store registry hives on compact flash.

This is what i have done.

1) Added "Hive-Based Registry to platform"

The following entries were added in my common.reg file

; @CESYSGEN IF FILESYS_FSREGHIVE
; HIVE BOOT SECTION

; Valid Bits for Flags registry value
; If no flags are set, the hive will be stored in the object store.
;
; 0x00000001 Start storage manager in boot phase 1 for hive-based
registry
; 0x00000002 Start device manager in boot phase 1 for hive-based
registry
; 0x00000004 Start storage manager in boot phase 1 for registry in
; external ROM (such as BINFS)
; 0x00000008 Start device manager in boot phase 1 for registry in
; external ROM (such as BINFS)

[HKEY_LOCAL_MACHINE\init\BootVars]
"SystemHive"="Documents and Settings\\system.hv"
"ProfileDir"="Documents and Settings"
"Flags"=dword:0
; END HIVE BOOT SECTION
; @CESYSGEN ENDIF FILESYS_FSREGHIVE

; HIVE BOOT SECTION
; This key allows untrusted processes (when using 2 tier trust model)
to access system files for read.
[HKEY_LOCAL_MACHINE\System\ObjectStore]
"AllowSystemAccess"=dword:1
; END HIVE BOOT SECTION


; Valid Bits for Flags registry value under
[HKEY_LOCAL_MACHINE\init\BootVars]
; 0x00000001 Start storage manager in boot phase 1 for hive-based
registry
; 0x00000002 Start device manager in boot phase 1 for hive-based
registry

IF PRJ_ENABLE_FSMOUNTASROOT

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\HDProfile]

ENDIF

; HIVE BOOT SECTION

IF PRJ_ENABLE_REGFLUSH_THREAD

registry value.

flush

ENDIF


; Registry value that can be queried to determine the type of registry
subsystem that is in use

[HKEY_LOCAL_MACHINE\System\ObjectStore]
"RegistryType"=dword:1
; @CESYSGEN ELSE
[HKEY_LOCAL_MACHINE\System\ObjectStore]
"RegistryType"=dword:0
; @CESYSGEN ENDIF

I have set the following variables to one in my
platform->settings->environment variables

PRJ_ENABLE_FSMOUNTASROOT = 1
PRJ_BOOTDEVICE_ATAPI = 1
PRJ_ENABLE_FSREGHIVE = 1

2) I have added the following to platform.reg file

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\ATAPI]
"Dll"="atapi.dll"
"Prefix"="DSK"
"DeviceId"=dword:0
"DMAEnable"=dword:1
"FSD"="fatfsd.dll"
"Flags"=dword:1000

[HKEY_LOCAL_MACHINE\init\BootV­ars]
"SystemHive"="Documents and Settings\\system.hv"
"ProfileDir"="Documents and Settings"
"Start DevMgr"=dword:0

When i download the image to my target board, the screen appears blank.
The image is never loaded. Can any one suggest if i am missing any
settings? Do i need to make any other changes?

Thanks in Advance.

Best Regards,
Sush.
