Re: Hive with self made Flash File System

So, currently you have the flash file system *not* mounted as root. Change
the location of the hive files to be on the flash. Capture the debug
messages. It's saying that it can't find the hive? The flash filesystem is
marked as bootable? So that the hive registry code knows what to wait for?
*Is* it waiting? Have you set the right things for starting device manager
and storage manager so that it will be started? You don't have any other
disk devices marked as bootable, right?

PSM is monolithic. It does not use a separate file system driver.

Hi !
Hi!

Apology if I was unable to explain earlier.

Actually I tried both using MountasRoot and MountasBootable flags for
particular profile I created and thereafter I tried without those flags.

I am actually able to see hive files in the storage device where its
getting
created.

But for some reason it's seems like not reading from those locations when
rebooting the system.

Depending on the Flags value I set below it either loads DeviceManager or
Storage Manager.
[HKEY_LOCAL_MACHINE\init\BootVars]
"SystemHive"="system.hv"
"ProfileDir"="Profiles"
"Flags"=dword:0
; END HIVE BOOT SECTION

When MyFSD driver loads, thereafter DeviceManager driver loads and just
hangs at BUSENUM.dll. Usually in any normal situation Block driver gets
loaded at this point.

I was curious if the Block Device Driver is required for Hive Based
Registry
Functionality?

As I had earlier mentioned that I do not have any Block Driver(or FMD) and
I
have implemented read/write NAND functionality in my File System Driver
itself. As my File System Driver is Monolithic.

Since I have my own FSD do I have to implement Registry read write
functions ?


Thanks!

I just told you! You're expecting to store the hive in \Documents and
Settings, but *that's not on the flash filesystem*! So, reading it back
won't work; it was never saved to persistent storage!

No I am not mounting the flash filesystem as the root.

So I made changes as below.
; HIVE BOOT SECTION
[HKEY_LOCAL_MACHINE\init\BootVars]
"SystemHive"="system.hv"
"ProfileDir"=""
"Start DevMgr"=dword:1
"Flags"=dword:3

[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\MYFSD]
"FriendlyName"="MYFSD"
"Dll"="MYFSD.dll"
"BootPhase"=dword:0
"LoadFlags"=dword:1 ; 1:load synchronously 2:load asynchronously

; END HIVE BOOT SECTION

Could you please let me know if I am still doing something wrong in
registry.

Thanks much!

Thanks for prompt reply.

I would appreciate if you could verify the registry settings.

; HIVE BOOT SECTION
[HKEY_LOCAL_MACHINE\init\BootVars]
"SystemHive"="Documents and Settings\\system.hv"
"ProfileDir"="Documents and Settings"
"Start DevMgr"=dword:1
"Flags"=dword:3

[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\MYFSD]
"FriendlyName"="MYFSD"
"Dll"="MYFSD.dll"
"BootPhase"=dword:0
"LoadFlags"=dword:1 ; 1:load synchronously 2:load asynchronously

; END HIVE BOOT SECTION

I am glad to know about PSM. In our case. FSDMGR does load the
MYFSD.
Either I am missing load order or some functionality.

Thanks!

You can use the hive registry with any storage device. Reading

probably indicates that you are not mounting the filesystem
properly
during
startup. I'm using Intel's Persistent Storage Manager, which
doesn't
use
FAT, and it works fine.

Hi!
Can I use hive functionality with self made flash file system ?
Flash File System is autoloaded using FSDMGR.
There is "NO" block driver. I use Flash File System driver with
self
made
NAND read/write routines. I have implemented all functions
required
by
File
System.

I am able to save Hive registry but not able to read back on
reboot.

Is it possible to use hive registry with any other file system
then
FAT?
