Module Name:
ntsetup\hwlog\hwlog.c
Abstract:
Logging some aspects of the hardware configuration to winnt32.log / setupact.log.
Esp. disk drive by connection, and map drive letters to disk drives.
Author:
Jay Krell (JayKrell) April 2001, May 2001
Revision History:
Environment:
winnt32.dll -- Win9x ANSI (down to Win95gold) or NT Unicode
libcmt statically linked in, _tcs* ok
actually only built for Unicode/NT, and does nothing
if run on less than Windows 2000
setup.exe -newsetup -- guimode setup
--*/
/* Platform notes
Win95:
apparently no setupapi.dll (redist)
apparently no cfgmgr32.dll
no kernel32.dll::GetVolumeNameForVolumeMountPoint
NT 3.1
no kernel32.dll::GetVolumeNameForVolumeMountPoint
NT 3.51
apparently no setupapi.dll
apparently no cfgmgr32.dll
no kernel32.dll::GetVolumeNameForVolumeMountPoint
NT4
no kernel32.dll::GetVolumeNameForVolumeMountPoint
setupapi.dll
has SetupDiGetClassDevs
does not have SetupDiGetClassDevsEx
does not have SetupDiEnumDeviceInterfaces
does not have SetupDiGetDeviceInterfaceDetail
cfgmgr32.dll
has the functions we call
Win2000, WinXp:
has all the functions we call
Win98, Win98se:
no kernel32.dll::GetVolumeNameForVolumeMountPoint
setupapi.dll, has everything we use
has SetupDiGetClassDevs
has SetupDiGetClassDevsEx
has SetupDiEnumDeviceInterfaces
has SetupDiGetDeviceInterfaceDetail
cfgmgr32.dll, has everything we use
has CM_Get_Parent_Ex
has CM_Connect_MachineA
has CM_Get_DevNode_Registry_Property_ExA
existing versions of
winnt32a.dll
not statically dependent on setupapi.dll
not statically dependent on cfgmgr32.dll
winnt32u.dll
not statically dependent on setupapi.dll
statically dependent on cfgmgr32.dll, all functions exported on NT4 and Win98
CM_Get_Device_ID_List_SizeW
CM_Get_Device_ID_ListW
CM_Get_DevNode_Registry_PropertyW
CM_Locate_DevNodeW
conclusions
works on Win2000 and WinXp
maybe some of it works on Win98, Win98se, Win9me
maybe can be changed slightly to work on NT4
cannot easily work on NT 3 or Win95
but GetVolumeNameForVolumeMountPoint and the DeviceIoControl might prevent it
dynamically link it "all"
