    - Using SetupDiSetDeviceRegistryProperty to change driver on a particular device A while back I spent a lot of time on NTDEV asking about changing the PnP IDs in a SCSI Bus filter so the PnP system would load a different class driver on a device. That worked fine for me, once I understood which IRPs to muck with. I didn't get around to running verifier on it, but from recent posts, running verifier could be a problem for me. Without Verifier, I could change all the instances of DISK to DIAG, for a particular PDO, and the system thought I had a DiagDevice. My Inf installs my DiagClas driver, I can enumerate the DiagDevices with the interface GUID the DiagDevice class driver exports, and everyone is happy. During that discussion, one of the MS storage guys suggested that SetupDiSetDeviceRegistryProperty, with the SPDRP_SERVICE property, could be used to change the driver for a specific device. For another use, I don't want to use the filter, so I'm trying to do this, with mixed results. The registry entry gets changed OK, and stopping and restarting the device causes my custom class driver to load, but it's not causing the PnP system to think it's something new, the system still thinks that it's a disk, so partmgr still attaches to it. Maybe I could use it that way, except that enumerating the interface GUIDs for disk and my diag driver doesn't find anything at all. So somehow this different driver in the stack for this one devnode has not only failed to produce a DiagDevice, it causes some impairment of the normal disk interface. I tried SetupDiSetDeviceInterfaceDefault with the DiagClas interface GUID in the SP_DEVICE_INTERFACE_DATA for the device, but that resulted in a 0xE0000225, which is ERROR_NO_SUCH_DEVICE_INTERFACE, in SetupAPI.h. Removing and re-enumerating results in my class driver not being loaded again. This isn't a surprise, since my custom class driver isn't signed, and probably never will be, so I expect the system to load the signed disk driver in the absence of my filter. So at this point, all I've done is substituted my custom class driver for disk.sys, and that's not what I want to do. I want to remove the device as a disk, and load it as a DiagDevice. So my question devolves to: Constraining to user-mode only, what else do I need to do to create a DiagDevice, instead of a disk with a different class driver? Remember that I can already do this OK with a filter, I'm trying to do it without using the filter. Since SPDRP_HARDWAREID and SPDRP_COMPATIBLEIDS are R/W, should I be changing those, too? Anything else I should change? Thanks, Phil -- Philip D. Barila Windows DDK MVP Seagate Technology, LLC (720) 684-1842 As if I need to say it: Not speaking for Seagate.

    - =?iso-8859-1?Q?Handel_to_=22\\.\Display1=22?= Hi there, Isn't it possible to create/open a handle to the graphic card? There is a symbolic link named "\\.\Display1" that links to the named Function Device Object (FDO) of the graphic card (\Device\Video0), but when I try the following: HANDLE hHandle = CreateFile( "\\\\.\\Display1", GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL); "hHandel" is set to "invalid handle" (0xffffffff) and GetLastError() returns "Access is denied" (5). All I want is to get a handle to the graphic card so that I can send some IOCTL's to it. Isn't it possible? Thanks and regards, Kent. Tag: Determine Processor Numbers Tag: 31735

    - Access VGA port SDA and SCL lines HI, I am using INTEL 82845G grapghic controller (which support DDC2BI protocol)and working on windows 2000 operating system. I am developing a software which will interact with the monitor through VGA port's SDA(system data line) and SCL(system clock line) data lines. According to access.bus protocol, pin 12 and pin 15 of a VGA port (D_SUB connector) are for SDA and SCl data lines. And they have given a protocoll about the data which should be sent to these data lines. Now my problem is how to send the data these lines through program. setSDA(), getSDA() .... should be the underline functions which will interact with the hardware (VGA port), which I guess should be implemented in the driver , now how to access these functions through my software? If I have to write a driver, I can use VideoPortDDCMonitorHelper function , but here also I have to supply the address were I want to send the data. I have to write the functions like typedef struct _I2C_CALLBACKS { PVIDEO_WRITE_CLOCK_LINE WriteClockLine; PVIDEO_WRITE_DATA_LINE WriteDataLine; PVIDEO_READ_CLOCK_LINE ReadClockLine; PVIDEO_READ_DATA_LINE ReadDataLine; } I2C_CALLBACKS, *PI2C_CALLBACKS; VOID I2CWriteClock(PVOID HwDeviceExtension, UCHAR data) { const ULONG nbitClock = 3; const ULONG Clock = 1 << nbitClock; PHW_DEVICE_EXTENSION hwDeviceExtension = HwDeviceExtension; ULONG ul; P2_DECL; ul = VideoPortReadRegisterUlong(DDC_DATA); ul &= ~Clock; ul |= (data & 1) << nbitClock; VideoPortWriteRegisterUlong(DDC_DATA, ul); } Can anybody over there guid me , how to write these functions and the addresses which I should supply so that it will get written on VGA port's 12'th and 15'th pin. for eg. this is sample code from 3dlab's driver, Now if I want to use same code, what will be the value of DDC_DATA, DDC_DATA is actually a virtual address of the DDC_control registor. Will it be same for all graphic chips? VOID I2CWriteClock(PVOID HwDeviceExtension, UCHAR data) { const ULONG nbitClock = 3; const ULONG Clock = 1 << nbitClock; PHW_DEVICE_EXTENSION hwDeviceExtension = HwDeviceExtension; ULONG ul; P2_DECL; ul = VideoPortReadRegisterUlong(DDC_DATA); ul &= ~Clock; ul |= (data & 1) << nbitClock; VideoPortWriteRegisterUlong(DDC_DATA, ul); } Also I want to know who supply the PVIDEO_PORT_CONFIG_INFO ConfigInfo parameter in the Find Adapter function? As to get the base affress I need AdapterInterface = PCIBus, but in my case, this whole struture is something like not accesseble. Please help There must be some predefined mapping of physical registers to the virtual registers, does any bbody is having idea about this mapping and how DDC control register will be mapped?

    - driver compile problem Hi, I am writing a WDM video capture driver by Win2000 DDK and VC6.0. My environment is Windows98 se. I put my source code under c:\xxxxxxx\wdm.nt directory, then build the source code. The generated .sys works well under Win98/ME, but it crash the win2k/xp immediately when it starts. Later I rename the directory to c:\xxxxxxx\wdm1.nt, (one more character), it works well on all Windows OS. My question is: Does it have any relationship between the source code directory name and generated .sys file? Or it is VC linker's problem? Tag: Determine Processor Numbers Tag: 31703

    - Error msg upon adding printer Hi, I am trying to install my custom printer driver via the Add Printer Wizard. Upon clicking on Finish, I get an error message saying: "Printer Driver not installed. Operation could not be completed." My .inf file installs 3 files: a graphic DLL, a UI DLL and a print processor. Error messages in setupAPI.log complained about the files not having digital signature information. This also happens to samples that come with the DDK. Does anyone know why I get the error message and how I can fix it ? Is it a must to have the DLLs properly implemented ? My goal at this stage is to install my print driver that does nothing. Regardless of what it does, I want to be able to install it at least. Many thanks, Michael. Tag: Determine Processor Numbers Tag: 31700

    - USB Bulk In&OUT each need two handles? Hi If my usb device has two endpoints - Bulk_IN and Bulk_OUT. I try to use the bulkusb sample code within windows 2000 ddk to communicate with my usb device. According to the sample code, it seems that I need to use two GUID based string plus the "\PIPEXX" string to CreateFile() in test application and get back two handles, one for Bulk_IN and the other for Bulk_OUT, if I need to bulk-in & bulk-out data to device. My question is that can I use one handle to bulk-in and bulk-out data ? If yes, which way is the best way and what can I do? ps. I try to use GUID based string but not plus the "\PIPEXX" string (for example, "\PIPE00") and CreateFile() is successful. The handle I got can used to send DeviceIoControl(), but can't used to WriteFile() ( or ReadFile() maybe) and gets the error code ERROR_INVALID_HANDLE.

For that I am going through the netvmini ndis driver source code, in the DriverEntry routine, the global variables are being initialized, and the comment says that "GlobalData structure is used to track the multiple instances of the same adapter". What does this mean? In which scenarios we might be having multiple instances of the same adapter running? Also, why do we initialize the GlobalData before registering the unload handler (I know the comment says that "unload handler has a more global scope"??)?

    - NDIS IM & Miniports & Bluescreens & how to support Hello, There is a well known problem between NDIS IM and Miniport drivers where the addition of the IM causes the Miniport to bluescreen. The solution is always upgrade the miniport to the latest, which has solved the problem. My problem as a vendor shipping an IM is when our product is installed the bluescreen happens so it is our products fault. Our support folks don't like having to tell customers to go get the latest driver from their NIC vendor. When I have looked at the fault it typically is a pointer dereference of an information buffer in a get or set oid. Does anyone have any idea what the underlying problem is with the minport. Why does it work without the IM? Is there anyway for the IM to protect against such problems? Thanks in advanced. Regards, Michael Wright Tag: Determine Processor Numbers Tag: 31632

    - TDI Drivers So, i have to write a VXD for doing this or it is transparent for the TDI Clients? All i have to do is to connect to a socket and communicate (as if like a regular socket application). In other words does the functions defined in TdiKrnl.h work under 98/ME? If not, then where can i get information on this VXD interface. I don't see anything in the DDK Thanks, Venkatesh. "Thomas F.

When I start the test it dispaly also other driver in box for testing with my IM driver sys file. After than the system restart and crash. May be this cause due to other system driver which is not related to us. So In Driver Verifier Test, It test only on our IM Driver or other system drivers ? Please give me detail about Driver verifier - NDIS Test for HCT 11.2 Kit for windows. Thanks in advance Bhavesh Tag: Determine Processor Numbers Tag: 31474

    - PCI device behaves differently in checked and free build I have a PCI device here which behaves differently in free and checked builds (using the same checked build driver, Win2000 DDK) of Windows 2000. In the free build, my ISR (which is called periodically, each time a hardware FIFO on the card is half empty) stops being called after a while (time varies, at least a couple of thousand interrupts, though), and after that I only read 0xffff from every register on the card, as if it was not there at all. In the checked build, however, the card continues to run smoothly! The card's registers are mapped with MmMapIoSpace(). Does anybody know what could cause this? PCI handling? Memory management?

Hello,

I am trying to use KeSetTargetProcessorDpc but do not know how to get the
processor number for each processor in a system. Can I used
KeQueryActiveProcessors and determine the processor number from the bit
number being set in KAFFINITY returned from the KeQueryActiveProcessors
call?

Much appreciated.

The processors are always numbered from zero, you can determine how many
processors by using KeNumberProcessors (note the definition of this changed
from 2000 to XP see
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndevice/ht
ml/keynumproc.asp).

Also be aware, that with hyperthreading a system with two chips can have
four
processors numbered 0 (chip 0) 1 (chip 1) 2 (chip 0) 3 (chip 1) so be
careful
on your planning.
