Re: HIVE registry in RAM under CE6

Tech-Archive recommends: Fix windows errors by optimizing your registry

Do you apply the following registry setting in your boot hive to prevent the
filesys to mount hive registry from external file system?

[HKEY_LOCAL_MACHINE\init\BootVars]
"Flags"=dword:0
"NoDefaultUser"=dword:0

Hi,
I am working on Windows CE 6 and I am trying to enable HIVE registry in
RAM:
IOCTL_HAL_GET_HIVE_RAM_REGION
IOCTL_HAL_SAVE_HIVE_RAM_REGION

My system was working fine under ce 5.0 but with CE6 I have an exception
in Filesys.

If I use HIVE registry saved on a volume, it works fine.

It seems that the registry is not initialized after I load HiveRAMInfo.
(see in the log ERROR:
C:\ymzki\private\winceos\COREOS\filesys\reg\reghive\.\registry.c line
1087: FSREG: Unable to mount clean system hive
FSREG: Unable to load system registry! Registry will be unavailable.)

Of course my function OALIoCtlGetHiveRamRegion, initialize the structure
(HiveRAMInfo) correctly and
memory region is zeroed the first time.

Regards
