    - How to write device installer? Hi, I'm in trouble. I have to write an installer for a modem, but have no idea how to do that. I've tried to execute *.inf files from driver's directory, but this didn't work. Could you please advise me how to do that or point me to some tutorials? Should I use some SetupDi methods? Thanks, K.

    - TextOut Hello , I have a strange problem which I have encountered in my code ,The DrvTextOut Method of my driver fails when tested with speedy , on further debugging I found out that it fails in the pcfallocatecachedFont method and at these lines // swap a cached font (using LRU method) pFCNode = ppdev->pFC->pUsedList.pPrev; //Change status into uncached pFCNode->pfo->pvConsumer = NULL; //clear glyph tag pjFCTag = (PBYTE) pFCNode->pjTag; for (i = 0; i < FC_MAX_GLYPH_ID; i += 4) { *(PULONG) pjFCTag = 0; pjFCTag += 4; } //for Now the problems are as follows: 1.The driver doesn't break at the same position all the time sometimes it breaks in the for loop some times just after the font is swapped .it also doesn't break for a specific font id it just breaks randomly. 2.The same driver is working fine with speedy on a Pentium 4 machine with 256 mb ram whereas the orignal machine is intel celeron with 196 mb ram. Now my doubts are : 1.Can this be because of the CPU speed , I think it might be a swapping problem because it is giving me a page fault in non paged area.if it is how can I make changes in the code to make it compatiable for the celeron platform. 2.The replacement algorithm I have used is incorrect,I should not use LRU . Please advise , as I am not clear if I am on right tracks.for further refrece I am attaching the pcfAllocatecachedfont method.

    - kernel driver refuses to run in safe boot I'm trying to write a very little SERVICE_KERNEL_DRIVER driver, which is supposed to run during safe boot. My current driver is as good as empty, I can successfully start & stop it during a normal (non safe) session. Also it boots up in a normal (non safe) session when being installed as SERVICE_SYSTEM_START. Everything looks just fine. But during safe boot XP suddenly is not able to load the driver. It tries to load it (I've added it to the safe boot registry keys), but it fails. The XP event log sais, XP was not able to load my driver, but it doesn't tell me why. If I check out the properties page of my driver (via device manager) after a safe boot I can see that it is not running. If I then try to manually start it, the dialog freezes for about 5 seconds, but the driver still does not run. What do I have to change to make my driver run successfully in a safe boot? Thanks! P.S: I tried to add power, pnp and wmi handlers, but that didn't help, either. Maybe I implemented them incorrectly, though. ============================================================ #include <ntddk.h> void UnloadDriver(PDRIVER_OBJECT DriverObject) { IoDeleteDevice(DriverObject->DeviceObject); } NTSTATUS DummyIrpHandler(PDEVICE_OBJECT DeviceObject, PIRP Irp) { Irp->IoStatus.Status = STATUS_SUCCESS; IoCompleteRequest(Irp, IO_NO_INCREMENT); return STATUS_SUCCESS; } NTSTATUS DriverEntry(PDRIVER_OBJECT DriverObject, PUNICODE_STRING RegistryPath) { PDEVICE_OBJECT devObj; UNICODE_STRING name; RtlInitUnicodeString(&name, L"\\Device\\MtsUpd"); IoCreateDevice(DriverObject, 4, &name, FILE_DEVICE_UNKNOWN, 0, FALSE, &devObj); DriverObject->DriverUnload = UnloadDriver; DriverObject->MajorFunction[IRP_MJ_CREATE] = DummyIrpHandler; DriverObject->MajorFunction[IRP_MJ_CLOSE] = DummyIrpHandler; return STATUS_SUCCESS; } Tag: How to differ the different network in protocol driver(802.3,802.11) Tag: 27707

    - scsi miniport HwStartIo() IRQL if no interrupts in a scsi miniport driver for a virtual HW(obviously no HW interrupts), if i set the PORT_CONFIGURATION_INFORMATION -> BusInterruptVector = 0; for findadapter and HW_INITIALIZATION_DATA -> HwScsiInterrupt = NULL can i be gauranteed that my HwStartIo() and/or HwTimer()will be called at DISPATCH_LEVEL(atleast)/PASSIVE_LEVEL? because i cant think of what DIRQL can SCSIPORT assume before calling into me? KeSynchronizeExecution() requires interrupt# question 2 ------------- since HwStartIo() can be called at DIRQL what syncronization mechanisms are available inside this routine to share data with a PASSIVE_LEVEL thread? even spinlocks are useless > DISPATCH_LEVEL. i am prepared to use any NTDDK only kernel functions thx alex Tag: How to differ the different network in protocol driver(802.3,802.11) Tag: 27705

    - WinDDK Fails to Build Examples I've installed the winddk 3790, read the release notes and getting started guide, and attempted to build the examples but I've had no luck-- the build is silently failing. Executing 'build -cZ' from the command prompt spawned by "Windows 2000 Checked Build Environment" rapidly scrolls through all the example directories (much too fast to be building) and exits without errors. If I look into an example (i.e. src\general\portio) at the build log file, I see entries like the following: > Compiling c:\winddk\3790\src\general\portio\sys directory ************* > 'nmake.exe /c BUILDMSG=Stop. -i NTTEST= UMTEST= NOLINK=1 NOPASS0=1 386=1' > Bad command or file name Any ideas? The log output is identical for every example driver in the DDK. I'd expect building examples to "just work" but I'm not familiar enough with this environment to even begin to guess what is wrong. It should be mentioned that I had this exact error mode using a previous Win2K DDK, so I elected to grab the latest 2003 Server DDK in the hopes that the integrated compiler, etc, would make the effort easier.

    - ScatterGatherList Fails Hi, I am using GetScatterGatherList for doing Bus Master DMA. It fails with status = "STATUS_BUFFER_TOO_SMALL". I have called it 9 times, but only two times it passes. What is the reason for this status code ? Which buffer is too small ? Number of MapRegisters allocated is 8. The buffer size to be transferred is 5120, it spans to a maximum of 3 pages. The following is the function call Status = DeviceExtension->AdapterObject->DmaOperations->GetScatterGatherList( DeviceExtension->AdapterObject, DeviceObject, mdl, // IRP->MdlAddress DeviceExtension->CurrentVaddr, // MmGetMdlVirtualAddress(mdl) transferSize, // 8192 or 12298 (2 * PAGE_SIZE or 3 *PAGE_SIZE) (PDRIVER_LIST_CONTROL) AdapterListControl, DeviceExtension, bOperationType); // bOperation = TRUE for a write, FALSE for a read.

    - [Q] USB Mass Storage Device IOCTL failure I'm developing a USB mass storage device with an additional functionality. There is no problem in locating the device's symbolic link, using SetupDiXXX functions. But if I try to DeviceIoControl() IOCTL_STORAGE_GET_DEVICE_NUMBER, IOCTL_SCSI_GET_INQUIRY_DATA, and other disk and storage control codes as well, after opening the device through CreateFile() with the following symbolic link name, it fails with the error code 50, which means ERROR_NOT_SUPPORTED. \??\USB#Vid_0c76&Pid_0005#0304281630200#{a5dcbf10-6530-11d2-901f-00c04fb951ed} To be more precise, my USB storage device supports Bulk-Only Transport protocol and announces itself as a SCSI transparent subclass device. If there is anybody who had ever stuck in this type of problem, please give me some clues for solving it. **** I have one more question. I'm in the position to develop hardware and software. So for now, I'm trying to compose a small program controlling a mass storage device of another manufacturer. If I'm to develop the firmware without relying on the USB controller customized to the specific application, do I have to write a firmware parsing all the SCSI command set? Or is there any documentation that specifies which part of the standard SCSI command set USB mass storage device spec supports? I'm afraid if I have to deal with a whole bunch of SCSI command set. Need some advice. Thanks Tag: How to differ the different network in protocol driver(802.3,802.11) Tag: 27664

    - Problems sending named events to Driver Hi NG My driver has problems recieving a event from my user mode applikation. But there is no problems recieving the same event in my appilication from the device driver. Thia is what I do: In my DriverEntry i create the event with this: // Create event for user-mode processes to monitor RtlInitUnicodeString(&uszNotifyEventString, L"\\BaseNamedObjects\\AppEvent"); // Trying to create the event NotifyEvent = IoCreateNotificationEvent(&uszNotifyEventString, &NotifyHandle); if(NotifyEvent) { // Success KdPrint(("NotifyEvent event created with success\r\n")); // Clear it... KeClearEvent(NotifyEvent); } I get the handle to the event in my application like this: // Creating event. ITs created by the driver.. hEvent = OpenEvent(SYNCHRONIZE, FALSE, _T("AppEvent")); if(NULL == hEvent ) { return 0; } They both succed. My application then waits for the event: // The events used.. hEvents[0] = pService->HEndThread; byNumOfEvents++; hEvents[1] = hEvent ; byNumOfEvents++; dwWait = WaitForMultipleObjects(byNumOfEvents, hEvents, FALSE, INFINITE); if((WAIT_OBJECT_0 + 1) == dwWait) { // Set event again. Driver does not respond to this SetEvent(hEvent ); <----- No responds in my driver on this } When my driver signals the event ( KeSetEvent(NotifyEvent, 0, TRUE) ) my application is responding OK to the event But when my application sets the event my driver does not respond to it. // Setting event KeSetEvent(NotifyEvent, 0, TRUE); <--- My application responds to this KeResetEvent(NotifyEvent); // Waiting for the service to answer status = KeWaitForSingleObject(NotifyEvent, UserRequest, KernelMode, FALSE, &WaitTimeOut); // Never reached. if(STATUS_SUCCESS == status) { KdPrint(("Got event.\r\n")); // Service has answered. Clear the event. Shutdown in progress KeResetEvent(NotifyEvent); } Any Idea ?? Schould I call the OpenEvent() with EVENT_ALL_ACCESS instead of SYNCHRONIZE ?? If I do I got an error that say "Access is denied". How can I create the event with privilege to do this ?? Thomas Tag: How to differ the different network in protocol driver(802.3,802.11) Tag: 27659
