    - LPD service in Windows XP rejecting spool job from Mac We are facing a problem while printing from Mac to Windows XP using LPD service. Windows is getting the print job control file and removing immediately. We trace the problem and found the reason. Mac is sending 1TeraByte as Spool job length. Can we get any patch to solve the problem in windows xp LPD service? Is there any solution to solve this problem? Any pointers are appreciated. Tag: VideoPortInt10 Tag: 67613

    - Whats wrong with my Old driver? I have changed INF file of general\portio driver which is shipped with XP DDK. I have just just changed the ports configuration in INF file for accessing the ECP (LPT1) printer port of my machine though before installation I manually changed system assigned resources of ECP (LPT1) port which were assigned by OS to avoide any confilict. CHANGES that I've made in INF file to drive the ECP port by genport.sys [PortIO.LC0] ConfigPriority=DESIRED IOConfig=378-37b(3ff::) ; 10 bit decode ranging from 378 - 37B Now every thing works fine as far as I'm using genport.sys to read\write the printer port but don't know why my existing driver is not working any more , any idea? My old driver use same port addresses. Tag: VideoPortInt10 Tag: 67591

    - Create bsod from user mode? Is there any user-mode equivalent of KeBugCheck, or some other way of causing a user-mode BSOD with a code that won't be easily confused with anything else (like 0xE2)? I have a hard-to-reproduce boot problem with a ps/2 keyboard filter driver. If everything is OK then I have a user-mode app restart the machine. If/when I can repro the problem I want something in user mode that'll cause me to drop into Windbg. (I know causing int3 will do it if I boot with /debug in boot.ini, but because the machine runs unattended and reboots every 5 minutes I wanted to try and use /crashdebug instead, so that when it goes wrong I only get the info relevant to the boot that fails) Tag: VideoPortInt10 Tag: 67587

    - Display "New hardware" wizard on an orphanded device programmatically We have situations where the user selects "cancel" on the new hardware wizard dialogs before the driver is completely installed (apparently they get confused or something.) The driver files have been pre-installed using SetupCopyOEMInf. This is a USB device and if they unplug and re-plug the device in the wizard comes up again and works fine (at least on XP where I'm testing.) Is there a way to do this from a program? I can detect the device on the bus and that it wasn't setup correctly. Now I want to "reinstall" the device to set it up correctly. If I right click in the device manager it displays the new hardware wizard. I want to do this from my application, just cause the new hard found dialog to appear and again and do its normal thing. Any way to do this? Thanx! Tag: VideoPortInt10 Tag: 67586

    - HELP! - ZwWriteFile() from a hooked ZwOpenFile() always crashes Hi My driver is hooking ZwOpenFile(). In my hook function, except calling the original ZwOpenFile(), I also call a logging function that uses ZwWriteFile() to print log data to file. For some reason, each time I call my log function from ZwOpenFile() and ZwWriteFile() is called, I get a BSOD with UNEXPECTED_KERNEL_MODE_TRAP (7f). The log function uses mutexes for synchronization. Using this log function from another hooked function (ZwCreateFile) works ok. Attached WinDbg's dump analysis. Thanks ================================================================ ******************************************************************************* * * * Bugcheck Analysis * * * ******************************************************************************* UNEXPECTED_KERNEL_MODE_TRAP (7f) This means a trap occurred in kernel mode, and it's a trap of a kind that the kernel isn't allowed to have/catch (bound trap) or that is always instant death (double fault). The first number in the bugcheck params is the number of the trap (8 = double fault, etc) Consult an Intel x86 family manual to learn more about what these traps are. Here is a *portion* of those codes: If kv shows a taskGate use .tss on the part before the colon, then kv. Else if kv shows a trapframe use .trap on that value Else .trap on the appropriate frame will show where the trap was taken (on x86, this will be the ebp that goes with the procedure KiTrap) Endif kb will then show the corrected stack.

    - Location of driver services in Windows XP64 and Windows XP Hi, In Windows XP if a driver service does not have a ImagePath ( or a BinaryPathName) then the SCM constructs the path as %Windows%\System32\drivers\<service name>.sys Two questions regarding this. 1. Can this default construction be changed to point to another location in WindowsXP ? 2. Is this behavior of construction of default path also occur in Windows XP64 ? If yes, then is the constructed path same as that of Windows XP ? Thanks Gaurav Chandna Tag: VideoPortInt10 Tag: 67558

I have check the registry for my pegas. It is registered successfully in MediaSet. I have try to use visualstudio 2005 to build x64 version or use my origanal 32-bit property.ax. They two are no use. And I use the vs2005 to trace in debug. I found that the *.ax is nerver be called when amcap want to show my property page. It nerver get into the DllGetClassObject function.

    - Firmware binaries and where to store them We have firmware, represented by binary files, stored on the hard drive, which are loaded onto our chip (which resides on a PCI card) by an unclassified WDM driver in Windows XP. During development, we have just installed those files into %SYSTEMROOT%\system32\ourfolder, but everyone on our team has access administrative access to those directories. If a consumer installs our card as an administrator and wants another user, without administrative privs, to use the card, this is a problem, right? In the DDK, under Still Image Devices...File System Access, I found a note that a driver could use the "All Users" profile, and create a subdirectory under the Application Data directory. Is this the best place to store my binary firmware images? When I install stuff and I want to keep record of it in the system registry, should I put it in HKEY_LOCAL_MACHINE/SOFTWARE/MYFOLDER?

    - stream header in single bulk packet in video class uncompressed bulk stream We're writing a video class device using XP SP2 built in driver. (Uncompressed, YUY2, 640x480, in bulk mode) Is it possible to send the stream header (as video class spec 2.4) at the beginning of a new frame in a separate packet, without any video data following in the same packet ? This is much easier when interfacing to external sensors without any external FIFO between, we can do that in the idle time between each frame. But seems that when we do this, Graphedit shows just a black screen. When we append some "test" YUY2 data, we see the test image. But "appending" video data in the same packet would be difficult, when interfacing to the real sensor (we're using FX2LP in slave fifo mode). Any experience on this ? Tag: VideoPortInt10 Tag: 67518

    - Windows Vista Mainboard Drivers Problems I have installed Windows Vista (Beta 1) on my pc but there was a great problem. My mainboard is a Gigabyte Intel Chipset and Windows doesn't install the good drivers. I tried installing the "old" ones (Xp drivers) but it didn't work. And since the mainboard is not set properly there is no way I can set up my soundcard (wich is onboard Realtek AC'97) or my network adapter (PCI - Realtek). Everytime I install any of them my PC simply resets and Windows restarts. Another strage thing happening is that windows detects automaticly my network card but loads it's own but it doesn't set it correctly. When I checked the system configuration from Hardware Manager, I noticed that at the PCI bridge section -> Resources there is a messege that says that it is not functional. I certanly would like to get this working so any advice would be great. Thanks. Tag: VideoPortInt10 Tag: 67517

    - vista driver compatibility Hi, A few general questions about device drivers in Windows Vista: - Will drivers for Windows XP work in Windows Vista? - If drivers are not compatible, how much work will it be to adapt them? Are there huge changes or is it a matter of recompiling with the new DDK? As you can see, I am not a driver developer myself, but I really need this information in order to push our suppliers in updating drivers. Maybe you can point me to some articles that answer these questions. With kind regards. Tag: VideoPortInt10 Tag: 67501

    - More 64 bit porting issues I hope someone can shed a little light here. I am trying to install a driver based on the bulkusb sample. It was recompiled successfully in an XP IA64 checked environment. The DDK is from the July 2005 DVD. I'm using VS .net 2003. No warnings, compiler linker state code being built for IA64. The target machine is a Dell 380 (Pentium D) and XP x64 Edition Version 2003 SP1. I'm building the driver on a 32-bit platform. The inf file was modified to use the decorations for ntia64. That got me beyond the "can't find software" hurdle. The New Hardware wizard finds the driver OK and then complains about not having a valid certificate but gives the option to install anyway. I select OK to install anyway. It then states "...driver is not intended for this platform". I've also built it using the Windows Server 2003 DDK for IA64 with the same results. There must be something else? Thanks for any pointers. Tag: VideoPortInt10 Tag: 67479

    - hook to DrvGradientFill does not work in my Customed 2k/XP printer driver Hello, Every one: I need some help on my current project. According to MSDN's document, graphic drivers can optionally support DrvGradientFill() by setting HOOK_GRADIENTFILL flag when it calls EngAssociateSurface or EngModifySurface. we have a costomed printer driver using a GDI managed surface with standard bitmap format. I was trying to recognize a graphic (vector) object (filled with a Gradient color) by intercepting DrvGradientFill(). Somehow, if I hook up DrvGtadientFIll() in printer driver, and trying to print a Gradient object from MS WORD 2003, GDI just calls DrvFillPath() and DrvStretchblt(), never calls DrvGradientFill(), Any body give me a hint?

    - Help me in writing win 2k Plug n Play driver for PCMCIA card Hi Everybody, We have win 2k device drivers(non plug n play) for PCI based add on card.Now we started writing Windows 2K device drivers(WDM, Plug n play) for 16 bit PCMCIA PC card.We are using ZILOG PCMCIA Adapter chip in our card. We filled the device related information like port base address,Port Range,Memory Range,Memory base and IRQ through Card Information Structure(CIS) touples. In case of pci card to detect a device we can check for Device ID and Vendor ID. How we can detect a PCMCIA device? For PCI card drivers we will get allocated resources from CM_RESOURCE_LIST structure. We can use that information as per standardized PCI configuration registers. In case of PCMCIA drivers, Allocated resources will be stored in the same CM_RESOURCE_LIST structure or no? If yes, in which format it is? Is it like same standardized PCI configuration registers? or any? Please guide me in writing the drivers for pcmcia card. If any mistake I have done in explainig my problem or if Iam going in a wrong way. Please guide me in right direction. Thank u Mahender Tag: VideoPortInt10 Tag: 67448

    - need help! Hello, I want to write a legacy multimedia driver which work in user mode. I did read MSDN and search the web and I have some understanding on how it would be implemented but I have some questions: 1- Is there any sample code that I can use as the base for development? 2- Do I need a specific version of DDK to develop such driver? 3- If I develop such driver, is it working with all versions of windows?

For example, LEDs on device, equalizer, 5.1 channels, etc. Where is a starting point of writing a driver of the device? Do I need to write a driver which replaces USBAudio or cooperate with USBAudio driver? Thanks. Tag: VideoPortInt10 Tag: 67397

    - PCI Port Replication for boot drivers? Greetings! I've a situation where NIC drivers are bound to an NDIS IM driver and a more regular filter driver, and in the process are made to be boot drivers (Start=0), in order to get the virtual disks set up early enough in the boot process (i.e. disk activity is sent across the network, and the presence of disks is simulated to Windows). What I need to do is to-by hand it appears-make the NIC appear as if its been installed in other slots-ones its never been installed in-for clients with the same NIC in different slots (same motherboard type). So basically I have to go to HKLM/System/CCS/Enum/PCI/VendXX_DevXX.../ and create an entry for each slot I want to go into. The entry here has the form A&B&C&D, where A,B,C,D are numbers of unknown origin. A seems to correspond to PCI bus?, B is unknown, C might be function, and D is unknown. One thing I could do is insert a card in each PCI slot and see how they're rendered in the registry, but that's non-deterministic to say the least. Any ideas about how I might otherwise tackle this problem? I can't rely on the standard DIFx tools (at least as I understand them) to pre-install a driver, because that requires PNP, which comes later in the boot process for a boot driver-too late for me, it appears. Any ideas are welcome... Thanks! Best, Steve Tag: VideoPortInt10 Tag: 67391

    - Sending child a resource at IRP_MN_START time I have been out out NT kernel mode for a while so I would appreciate if anyone can help me. Is there currently a way for a Physical Device Object to respond to PnP IRPS (defining a new resource or sharing one of its own) such that the child's Functional Device Object receive its PnP IRP with minor function START and its stack location points to that resource? thanks Tom Currently I am defining an internal irp that the fdo sends to the pdo and the resource is returned. Also I saw a suggestion to do a filter with a custom connection between the filter and pdo. but in that case I see no advantage of that rather than a custom call between fdo and pdo.

    - AVStream generating INVALID scatter/gather DMA mappings in Windows XP x64... Oh dear, look what AVStream is passing to my BDA minidriver as KSSTREAM_POINTERS on Windows XP x64: KsStreamPointer->Offset structure: Count = 12 (mappings) Remaining = 12 Mappings[ 0]: PhysicalAddress = 0x00000000:AE772400, ByteCount = 3072 Mappings[ 1]: PhysicalAddress = 0x00000000:AE76B000, ByteCount = 4096 Mappings[ 2]: PhysicalAddress = 0x00000000:AE76B000, ByteCount = 4096 Mappings[ 3]: PhysicalAddress = 0x00000000:AE76B000, ByteCount = 4096 Mappings[ 4]: PhysicalAddress = 0x00000000:AE76B000, ByteCount = 4096 Mappings[ 5]: PhysicalAddress = 0x00000000:AE76B000, ByteCount = 4096 Mappings[ 6]: PhysicalAddress = 0x00000000:AE76B000, ByteCount = 4096 Mappings[ 7]: PhysicalAddress = 0x00000000:AE76B000, ByteCount = 4096 Mappings[ 8]: PhysicalAddress = 0x00000000:AE76B000, ByteCount = 4096 Mappings[ 9]: PhysicalAddress = 0x00000000:AE76B000, ByteCount = 4096 Mappings[10]: PhysicalAddress = 0x00000000:AE76B000, ByteCount = 4096 Mappings[11]: PhysicalAddress = 0x00000000:AE76B000, ByteCount = 4096 Mappings 1 through 11 point to the same physical address. Thus the DMA transfer can never work right X-( Now what's puzzling is that when I use pretty much the same code on different _hardware_, AVStream generates correct mappings perfectly ok. One noticeable difference between the hardware that works and the one that AVStream generates invalid mappings for is that plugging in the latter card reduces the memory displayed by the BIOS(!) from 4GB to 3.75GB, whereas the working hardware does not. So I figure there must be something about the PCI configuration space that makes the BIOS reduce the available memory by 256MB _and_ Windows XP x64 generate incorrect scatter/gather DMA mappings. But what could that be? And how can I work around that? Puzzled,« -- Robert Schlabbach e-mail: robert_s@gmx.net Berlin, Germany Tag: VideoPortInt10 Tag: 67092

    - avstream/bda driver uninstallation and re-installation issues Basically this has to do something with the sw-enumerated drivers. I install the avstream/bda sample drivers by right clicking the inf file. all is fine. I un-install the drivers in this way.. 1>Uninstalling from device manager 2>running rundll32 with streamingdeviceremove option. I thought these 2 issues should be sufficient to remove the driver. Now I wanted to update the driver and therefore, I copied the updated drivers into the directory and installed the driver by right clicking the INF file.For some reason it still installed the old drivers from the previous install. I found out that, this happens because Windows is caching the data in repository directory under windows\system32\driverstore. if I remove all references to my inf and drivers from the repository, then the newer drivers get installed. But this all is just too messy. Isnt there a better way ? 1>How do I update the drivers ? assuming I change something and want to test them 2>un-install and reinstall them without going through and deleting references to the INF and drivers that I had previously installed.

    - Is the MUX Sample Drive Incorrect? According to MSDN here (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/network/hh/network/204_802p_7a58dda8-5561-496c-bcac-5ac7b0bdac2e.xml.asp), on receive miniport drivers are supposed to remove the tag header vlan information and place it into the OOB data if the configured VLAN ID of the NIC is 0 and the packet contains a tag header. Therefore, if a packet was being received, it will have to go through the miniport driver before ever reaching the MUX driver --- right? So wouldn't the VLAN information be stripped out of the tag header and the MUX driver would never see it? Tag: VideoPortInt10 Tag: 67084

    - XP log in notification Hi all, Is there an easy way to tell from a "C/C++" application if a user has logged on to XP and the desktop is being displayed ? I'm seeing some problems because I have a thread in my printer driver that XP starts up before any users have logged in. And this thread tries to add a status icon in the system tray. I get an error on Shell_NotifyIcon, and I'm assuming this is because the login has not happened yet, because if I log on right away, there is no problem. There must be some function that returns this kind of system status, but I can't seem to find it. Thanks! Tag: VideoPortInt10 Tag: 67080

    - AVStream driver On changing frequency from graphedit I expect to receive multiple calls to the set property handler for KSPROPERTY_TUNER_FREQUENCY. Under what circumstances would an AVStream driver receive just one call. Also this follows a call for KSPROPERTY_TUNER_STATUS which is missing in my case. The result of this misbehaviour is that the analog tuner control in graphedit always says "Locked". Tag: VideoPortInt10 Tag: 67077

    - modifying the bios from a driver I have recently inherited a driver for a family of PCI expansion products. The driver is written in C++ and attempts to be one of those that supports every OS/platform etc. known to man. This of course makes it incredibly hard to maintain. Simply the driver (filter to PCI.SYS) needs to discover the devices below it and make sure there are enough resources to support them. (I/O and memory) If need be, the driver modifies the PCI BIOS so that any bridges above it have enough resources and then requests the user reboots. One of the products is a carbus, so we don't know what resources we need at boot time which is the reason for the reboot. This driver broke with Windows XP SP2, I found a white paper that provided a workaround located at the link http://www.microsoft.com/technet/prodtechn...n/sp2mempr.mspx however the driver appears to still have the problem with the 64 bit AMD Turion (running 32 bit windows XP SP2). I suspect the problem is during the modification of the BIOS. I can't seem to find a lot of documentation on how to do this. The current driver does it by switching the machine to V86 mode and calling the BIOS. Where can I find the correct documentation I need to figure out how to modify the BIOS from a windows driver. As I said the driver is hard to maintain, and there is a lot of code using undocumented techniques in windows that are no longer supported for example hooking on kernel functions. I would like to re-write the driver the correct way (at least in my opinion), so I am attempting to collect all the info I need. I'm also not locked into any method, if there is a simpler way to do things that minimizes user interaction I'm all for it. Thanks, Brian Tag: VideoPortInt10 Tag: 67076

Hi Shatskih,
Our driver is simple kernel mode driver and I need to call
VideoPortInt10().But this function requires first argument which I don't
know how to get.What I study is display driver is transparent to other
drivers and only
filter driver/mini port drivers can call that function. Please tell me how to
call this function from a simple kernel mode driver.

thanks in advance,
Krishna

The DDI is meant to be called from a video miniport driver only, and is
not meant as a general purpose kernel driver DDI. The first parameter,
as the DDK documentation makes clear, is a "pointer to the miniport
driver's device extension".

How are you going to synchronize your access to this bios resource with
other concurrent accesses?

You can have your video miniport expose a interface that can be called from
another driver, then call VideoPortInt10 from the miniport.

If you don't have the source for your miniport, then it is extremely
unlikely that you are going about things the right way. What INT 10
services do you plan to call?
