Routine Description:
|
||
|
||
Loads the registry log file for the system hive from <BootDirectory>\config\system.LOG.

||
|
||
Allocates a memory descriptor to hold the hive image, reads the hive
|
||
image into this descriptor,

||
|
||
Arguments:
|
||
|
||
DeviceId - Supplies the file id of the device the system tree is on.
|
||
|
||
DeviceName - Supplies the name of the device the system tree is on.
|
||
|
||
DirectoryPath - Supplies a pointer to the zero-terminated directory path
|
||
of the root of the NT tree.
|
||
|
||
HiveName - Supplies the name of the system hive ("SYSTEM.LOG")
|
||
|
||
LogData - flat image of the log file
|
||
|
||
LogLength - length of the data in LogData
|
||
|
||
Return Value:
|
||
|
||
TRUE - system hive successfully loaded.

function.
|
||
|
||
Arguments:
|
||
|
||
DeviceId - Supplies the file id of the device the system tree is on.
|
||
|
||
DeviceName - Supplies the name of the device the system tree is on.
|
||
|
||
DirectoryPath - Supplies a pointer to the directory path of the root
|
||
of the NT tree.
|
||
|

Fontfile - Supplies the filename of the OEM font file.
|
||
|
||
BadFileName - Returns the filename of the OEM font file that was missing
|
||

||
Return Value:
|
||
|
||
ESUCCESS is returned if the OEM font was successfully loaded. Otherwise,
|
