    - How to get the device instance id of a disk or volume? I am developing a software where I store the Instance ID of every disk in the system. How can I get the Instance ID from a disk number? e.g I want Instance ID of DIsk0 DIsk1 etc.? here is what I am doing 1] SetupDiClassGuidsFromNameA("DiskDrive",***); to get the GUID for disk drives 2]SetupDiEnumDeviceInf(***) to enumrate all the disks.This gives me Instance ID's of all the disks but how can I get the device instance ID of spesific disk(like Disk0)?

    - Creating a virtual network card (VLAN) from a script I'm looking for a way to create a virtual network card from a script instead of Windows UI.. I succeeded to install the Protocol driver from a script but didn't find a way to create new VLANs without using the UI. I used the notify dll that comes with mux sample in WDDK. My questions are: - Can I expose a new method in my notify dll for adding a new VLAN, and call it from a script? - Is there a generic tool that makes it? - Do you have a sample code?

    - Driver installation warning, driver signing and WHQL Hi group, I have a device driver from FTDI which I am using in my software product (for Windows XP). The driver is already WHQL cedrtified. I changed the driver .inf file such that it contains my company's vendor- and product ID which results in loosing the WHQL certification. Software and driver work as expected but: The driver is not installed automatically during the software installation procedure. Instead, Windows complains about the driver and says it is not signed/certified and may harm my computer. 1) How do I get rid of those warning dialogs during driver installation? My guess is that the driver has to be (re-) certified/ signed. Is that true? 2) How do re-certify an already WHQL certified device driver? I figured out that there is the WHQL reseller program. To participate, I (my company) has to sign a lot of legal stuff. Before I continue, I would like to know if I am on the right track... 3) If the WHQL reseller program is the right thing to do to get rid of the warning message during installation, what is the result of this? How is my driver resigned/recertified? Will I get some file from Microsoft with magic information telling the driver is fine? If so, what do I do with this file? 4) I searched the Microsoft WHQL internet pages but it drives me crazy. I cannot find the information I need. Is there a source of useful (!) information about driver signing/certifying and WHQL you can point me to? Thanks for your answers! Regards, Paul Tag: Regarding DTM set up for LAN. Tag: 102689

    - kernel memory Hi, i have a very basic question regarding kernel memory allocation. is allocating kernel memory always performed on some kind of pool (paged or nopaged) ? is there any memory allocation methods that acts on a "regular" memory, meaning type of memory other than paged or nopaged ? since kernel memory space is about 1G, i'm a bit confused since both the paged pool and the non paged pool are smaller than 1G. so what with the rest of the memory ? can i allocate more than the pools have to offer ? if so, how ? since all the routines deal with a pool type (paged or non paged). thanks a lot, kobi.

    - NDIS6 - Renew IP Address Hello, I'm writing a miniport driver for NDIS6 (Vista) which emulates 802.3 network device, but the actual physical device is different. Within a certain scenario I need the overlying protocol(s) to renegotiate the IP Address. I'm trying to follow the MSDN documentaion thus sending the status NDIS_STATUS_NETWORK_CHANGE with the specific NDIS_NETWORK_CHANGE_TYPE (NdisDefinitelyNetworkChange or NdisPossibleNetworkChange, i've tried them both). Unfortunatly, I couldn't obtain a new IP Address. when I run "ipconfig /renew" manualy I get a new IP easily. I've also seen in a sniffer that no DHCP Request is sent when my miniport indicates the status above (NDIS_STATUS_NETWORK_CHANGE ). In the past, for my previous miniport driver for NDIS5 (XP) the "trick" to renew the IP from the miniport was to indicate "link down" and "link up" in a row. in that case it worked fine. But now, running with NDIS6 I dont know the correct method for doing it. Can anybody help? Thanks Yogev Tag: Regarding DTM set up for LAN. Tag: 102648

    - File filter driver or MUP network redirector? Hi I have a design session coming up where the ultimate aim is to protect parts of the file system from prying eyes using either a MUP network redirector ( assuming file system mounted through remoted shares) or a file system filter driver using filter manager. I need to clear up some assumptions : Is mup a client or server side ( or both ? ) technology ? I understand I need to write a network redirector driver that owns a VNC path and will manage access to that path. If the unc path is on a file server - what needs to be done at the file server ? The file mini filter will need to intercept all calls to the filesystem. I have big fears about all the different MJ call types I will have to handle - fast IO, asynch io etc. What is the best plan to handle this - my opinion is to route them all through a common procedure and allow/disallow access as appropriate ut this can be a lot of different calls which expect different handling. This may lead to deadlocks and performance problems if not very carefully handled on a busy fileserver. The major benefit to me of the latter is that it can be installed everywhere - so a common build. Any commentsw or guidance as when to use one and when to use the other. The WDK docs on MUP haven't been terribly clear to me yet. regards Mike Tag: Regarding DTM set up for LAN. Tag: 102645

    - Problem reconfiguring PCI-e device in Vista Hi, I'm writing a driver for a proprietary PCI-e adapter. The board contains multiple FPGA-based PCI-e devices behind a PCI-e bridge. From time to time, we need to reconfigure the FPGA's while the system is alive. We do not however want the system to reboot (think of it as hot- swapping without physically replacing the device). The problem is that the FPGA's incorporate the PCI-e interface so that they cannot be reconfigured while they are active. In XP we finally managed to reconfigure the FPGA's by first calling CM_Query_And_Remove_SubTree() on the bridge (being the parent devices of our FPGA's). This causes the FPGA-devices to be switched to the D3- state, after which they can safely be reprogrammed. We then call CM_Reenumerate_DevNode() on the parent of the bridge device so that the new FPGA-devices are recognised again. In Vista however, the system seems to automatically re-enumerate the PCI bus immediately after the CM_Query_And_Remove_SubTree() has completed. This causes the FPGA's to be accessed while they are being configured resulting in a BSOD (Machine-check-excpetion). - Any idea how to disable (or delay) the re-enumeration of the PCI- bus? - Any link to more extensive documentation of the internals of the PnP system? I've found many ways to manage PnP devices, but little or no information about what is happening behind the scenes. - Any suggestions for alternative methods to achieve the reconfiguration? Note: redesigning our hardware is no option. Thanks in advance for your help, Koen Tag: Regarding DTM set up for LAN. Tag: 102638

    - INF file for SMBus driver Folks, I am writing a client driver for an SMBus device on a PCIe card. The SMBus device gets detected by the host controller. I can see the device listed by utilities like SpeedFan. The SMBus device uses a persistent slave address (actually an I2C device posing as an SMBus device). My question is how does one write an INF file for such an SMBus device - more specifically, how does one describe the device. I found this entry in the acpi.inf file - %SMBALI.DeviceDesc% = SMBALI_Inst,ACPI\SMBUS&VEN_10B9&DEV_7101 I guess this will work for devices that use dynamic address and get their address using ARP because the device id and vendor id will be available to the SMBus host controller from the device's UDID. But for SMBus devices that do not have things like UDID how does one specify the device description. Thanks, Ashwat Tag: Regarding DTM set up for LAN. Tag: 102634

    - Validating parameters for IoDeviceControl in KMDF -> KMDF verifier error When testing my driver to be crash safe for various user input, I came across an issue in my driver that I don't know how to handle. To eliminate my own driver, I tested the same thing with the original WDK (WDK 6000) sample osrusbfx2 driver. By modifying the testapp to send erronous input to the driver, I could get the error/break even there. The sample uses the parameters\wdf\DbgBreakOnError = 1. Now I wonder how it should be handled by the driver, as the KMDF says it's an error. How to reproduce: To have some common code to look at, I use the sample KMDF osrusbfx2. Modify the testapp to call the driver with IOCTL_OSRUSBFX2_GET_7_SEGMENT_DISPLAY and put erronous parameters in the call: if (!DeviceIoControl(deviceHandle, IOCTL_OSRUSBFX2_GET_7_SEGMENT_DISPLAY, &sevenSegment, // Ptr to InBuffer, NULL in example sizeof(UCHAR), // Length of InBuffer, 0 in example &sevenSegment, // Ptr to OutBuffer 0, // Length of OutBuffer &index, // BytesReturned 0)) { // Ptr to Overlapped structure I've only seen it when input buffer pointer and length is valid and the output buffer pointer is correct but oputput buffer length is zero. By turning on Parameters\Wdf\DbgBreakOnError, I get: >KMDF detected potentially invalid operation by canusb.sys. Turn on >framework verifier to break into the debugger. Turning on the verifier gives me >410: FxRequest::CompleteInternal - Caller of this WDFREQUEST 7A104170, Irp >0x862BB398 is passing an OuputBuffer address even though the >OutputBufferLength is zero <yes, there is a spell error in the log: OuputBuffer> So, here's my question: if this is a driver error, how can it be corrected?

    - Got few questions/doubts about MDL (after browsing archives/web) on this subject Hi, Working on a problem at hand with miniport network driver. I have few questions related to MDL & NET_BUFFER. My questions are: 1. What is the maximum size of virtual address-range that a single MDL can map? (I am under the impression that only one page of contiguous virtual address range can be mapped by a **Single** MDL. Let me know if this is wrong). 2. If a single buffer whose virtual address range is more than 8 K (size of receive buffer is more than 2 page assuming 4K page size), how many MDLs would be required in the *LEAST* to map the entire virtual address range? Answer to Q#1 will probably answer Q#2 as well. If not pls include answer for this as well. 3. Can ByteOffset be more than size of one physical page? I see that ByteCount value of Mdl returned by NdisAllocateMdl (length = 9k) set to 9K. 4. I have got a buffer whose size is more than 8K and I use NdisAllocateMdl to allocate Mdl to map this buffer passing start address of this buffer and complete length of this buffer. But I receive a single MDL in response to this operation? Does that not mean its mapping only part of buffer I passed? When I tried changing virtual address from (start address) to (start address + 5k), Mdl->StartVa & Mdl->ByteOffset changes to reflect next page which seems to answer my aobve question that it maps only part of the buffer. But still want to get it verified from experts on this list. How to get MDL chain mapping for the complete virtual address range and not just the first page of the receive buffer? Should I explicitly call NdisAllocateMdl() in loop for entire range starting from the start-address stepping through at size of 4k? 5. If I call NdisAllocateMdl on a buffer with address say X. I receive an Mdl and after executing some code, I realize that I need to indicate data to NDIS starting from X+5K. Can I pass the above allocated Mdl & NET_BUFFER to do this by manipulating DataOffset/ByteOffset? Thanks, -Praveen I see the following information in OSRonline doc on MDL: // Notice that while in the context of the subject // thread, the base virtual address of a buffer mapped // by an MDL may be referenced using the following: // // Mdl->StartVa | Mdl->ByteOffset typedef struct _MDL { struct _MDL *Next; CSHORT Size; CSHORT MdlFlags; struct _EPROCESS *Process; PVOID MappedSystemVa; PVOID StartVa; ULONG ByteCount; ULONG ByteOffset; } MDL, *PMDL; Also you know that StartVa is the page aligned virtual address of the start of the range and ByteOffset is the starting offset into the first page. TRIVIA POINT: MmBuildMdlForNonPagedPool sets the MappedSystemVa of the MDL to (Mdl->StartVa | Mdl->ByteOffset) and then sets the MDL_SOURCE_IS_ NONPAGED_POOL bit in the MdlFlags.

    - Log Mejor Functions I want to log (in memory in circular list type space- so I get it on BSOD) all mejor function calls with some call parameters. I am thinking about setting all mejor function to a single function, log it there and forward to real function and log again on return. Would that be a good idea?

    - How to delete the Tab "Layout" or "Paper/Quality" in Postscript Dr I'm writing a Customised Postscript Driver which is based on "PS5UI.DLL" and "PSCRIPT5.DLL". When Printing Perference window displays, I want to display the tab that I created by myself and I do not want to display the tab "Layout" or "Paper/Quality". The question is, how can I delete the tabs "Layout" or "Paper/Quality" from Printing Perference window? the following method I used is failed,because I can't get the handle of tab "Layout" or "Paper/Quality" .

    - suggestions needed for developing a printer driver I have no expereince on wrting a printer driver and need your advices or suggestions on developing a unidrive based image driver. I have downloaded WDK/WDF, built the samples by using "build -cZ", and tested the sample image driver in Print section. Now I need to modify the src code, integrate more stuff together, and do debugging soon. Is Visual Studio 6.0 a good IDE for this project? Do I need SDK for this? Is WDK the only one I need? Do you have any other advices or suggestions for me? Thanks in advance! Tag: Regarding DTM set up for LAN. Tag: 102571

    - Synchronising read and write ops All, I am writing a very basic on the fly encryption file system filter driver as a learning exercise. I was planning on: 1. Storing the real length of the file and other information in a header 2. Reading and writing the header as part of non-cached and paging IRP_MJ_READ and IRP_MJ_WRITE operations. 3. Returning the length from the header for IRP_MJ_QUERY_INFORMATION Irps. I was planning to use a driver managed queue of Irps so that I could ensure the I could update the header in response to a write before a another thread read the header; classic synchronization problem. However, I discovered that most (if not all) of the operations use Irp->UserBuffer, and in my driver dedicated thread I would have to change process context all the time to access the buffer, which strikes me as both dangerous and extremely slow. So, my question really is how would one generally synchronize this kind of thing? Could I use an ERESOURCE and have any read operations acquire shared and write operations acquire exclusively? Is it safe to enter a critical region for all read and write Irps? Many thanks in advance! Carl Tag: Regarding DTM set up for LAN. Tag: 102570

    - DiskId32 has trouble reading some SATA drives My DiskId32 tool, http://www.winsim.com/diskid32/diskid32.html , reads hard drive information directly from the hard drive in Windows Vista, XP, Win2K, Win9X, etc. DiskId32 works in three modes: direct using administrator rights, indirect using the scsi bypass and direct using user mode rights. The scsi bypass was dropped in Windows server 2003 and Vista. Please note that the source code for DiskId32 is there also. For some reason, the direct reading of the hard drive using user mode rights is failing for some SATA hard drives. However, the direct reading of the hard drive works fine in administrator mode. Specifically, what is failing is the reading of the serial number of the hard drive. The identify bank being returned by the hard drive is only 121 bytes long and the serial number pointer is at position 120 which has a zero in it. I would appreciate any insights or thoughts people might have for this issue. Thanks, Lynn Tag: Regarding DTM set up for LAN. Tag: 102562

    - KMDF filter driver not loading in safe boot mode We have several filter drivers using KMDF, and we noticed that under Windows XP SP2 they fail to load when you boot in safe mode. Seems that wdf01000.sys is not loaded in safe mode, causing the filter driver to not load. Issue is not present in Vista. Was able to fix this issue by adding the following registry key: HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\WdfLoadGroup Is this a known issue? Was not able to find any information on Microsoft, but seems that some other people had the same issue. Thanks for any help, Olivier Tag: Regarding DTM set up for LAN. Tag: 102560

    - Storport driver dropping HBA API events? Hi, I have taken the TempConsumer SDK example and converted it to consume the MSFC_AdapterEvent class. I have a Fibre Channel driver that fires multiple events (using ScsiPortFireWmiAdapterEvent) in rapid succession. However, the consumer only sees the first event. If the events are fired a few seconds later, again I only see the first event. Is there a limitation for firing events? If so, how is an event like this one supposed to work when there is unique data (the event type) each time the event is fired? Thanks, Scott Tag: Regarding DTM set up for LAN. Tag: 102545

    - Mysterious change in DbgPrint functionality I just solved a problem that was baffling me. I was trying to debug a driver on Vista Home Premium (32-bit) and, following advice I found online, I disabled User Account Control (UAC). All of a sudden, DebugView stopped showing messages from my driver. Turning UAC back on didn't fix it. I eventually solved my problem by creating a REG_DWORD value named DEFAULT, value -1, in HKLM\System\CurrentControlSet\Control\Session Manager\Debug Print Filter. My assumption is that disabling UAC deletes that key and re-enabling UAC doesn't put it back. -- Walter Oney, Consulting and Training http://www.oneysoft.com Tag: Regarding DTM set up for LAN.

    - CreateFile not working in vista-32 Application is calling CreateFile("\\\\.\\xxxx", GENERIC_READ | GENERIC_WRITE, etc.). Works great on Vista Ultimate (64-bit) and all pre-Vista 32-bit systems. Fails on Vista Home Premium (32-bit) with ERROR_ACCESS_DENIED. IRP, if ever generated, is not getting to my driver. App is running from command prompt running as administrator. Device object is created with call to IoCreateDeviceSecure specifying a valid setup GUID and SDDL_DEVOBJ_SYS_ALL_ADM_ALL. Objdir shows that there is no DACL on the device object, which presumably explains why CreateFile is failing. (There is a DACL on the symbolic link, and it allows R/W access by administrators). -- Walter Oney, Consulting and Training http://www.oneysoft.com Tag: Regarding DTM set up for LAN. Tag: 102540

    - Synchronizing MiniportResetEx with other Miniport entry points Hi, When MiniportResetEx is pending in the Miniport Driver, will NDIS call any other MiniportXXX entry points till Miniport says NdisMResetComplete (mainly oid, tx, adapter state transition and tx/ oid cancel routines)?

    - Disable driver signature enforcement in vista x64 business edition I am working on pci driver development for visa x64OS, i wanted to test my driver, whether the driver is working correctly or not. I installed my driver as i did in xp-32, 64 bit driver loaded correctly but, driver is not running, it is stopped(i verified with sc query name), i have choosen the option to "SERVICE_SYSTEM_START", though i tried to restart the driver using devcon, it says it is stopped & it is not running in vista x64. Since i am under development phase, driver is not signed, While installing the driver, it asked a pop up saying that driver is unsigned, i have choosen to install it. is the driver stopped instead of running, is it because of driver signing problem? I tried to disable driver signature enforcement using F8 option during system startup, but i dont see any difference, also treid with some bcdedit options, its same. currently i am looking KMCS_walkthrough.doc about, how to test sign the driver. Is this is the only way to test the driver, do i have to test sign the driver everytime, when the driver code is modified? Is this is the problem related to driver signing? while booting the system, i have choosen F8 to disable & tried some bcdedit options, still the result is same.

    - Select_Config in WinCE5.0 Hi, I'm developing a USB driver for WinCE5.0 and planning to support a device with multiple configurations. I don't see any USBD interface for Select_Config. Then I was planning to issue a vendor transfer for a select_config. However, in one of discussion forums, I found out that we should not issue a vendor request for a Select-Config. Instead it should be a Control transfer. As am writing a function (client) driver, I don't have the pipe_handle to issue a control transfer!! Then I found one more post regarding the same in another discussion forum. It highlighted the steps as below - You should be able to select any device configuration using the following CE USB functions: ClearFeature: Sends a CLEAR_FEATURE request to a USB device. GetDescriptor: Sends a GET_DESCRIPTOR request to a USB device. GetInterface: Sends a request to a USB device for information about alternate device settings. GetStatus: Sends a GET_STATUS request to a USB device. SetDescriptor: Sends a SET_DESCRIPTOR request to a USB device. SetFeature: Sends a SET_FEATURE request to a USB device. SetInterface: Sends a SET_INTERFACE request to a USB device, to change the device's settings The first step says, I should send a CLEAR_FEATURE. My question is, issue CLEAR_FEATURE to clear what? Should I send USB_REQUEST_SET_CONFIGURATION as the "wFeature" argument in the call lpClearFeature? I tried this, but I got a USB_STALL_ERROR in return!

    - Windows Vista wireless interface Medai unauthenticated Hi, I am currently testing wifi compatibility on Windows Vista. To connect our Wifi adapter to the network we use our own application and supplicant. Our driver blocks windows from changineg the driver state and we have our own OIDs to associate and authenticate. We use IPHelper to catch IP configuration. This all works fine on XP but does not work on Vista. On Vista this works great for the radio, and my wifi interface become "Enabled" in Network Connection Panel, but DHCP never succeed to give me an IP configuration. On the command line, by typing "ipconfig", I can see my wifi interface hanging in media state "Media unauthenticated". Well sometimes if the ap is WEP only it works after a long delay but if the the security is WPA or WPA2 we never get an IP address. It also seems that if I set a static IP on the interface then IpHelper never reports the static IP. Any thoughts? Thanks Tag: Regarding DTM set up for LAN. Tag: 102516

up of LAN, is it Ok if I use one client machine with XP OS and another client
machine with Vista OS ? More precisely the NDIS test server will be mchine
with XP loaded and the NDIS client machine will be with vista loaded. Is it
ok?

Ask these questions in microsoft.public.development.device.drivers.dtm. I
think the Server and Controller must be Server 2003.
