    - Help, why PCI bus master memory read fails, many retries? I have a PCI device that seems to be unable to read from main memory but only after a large amount of virtual memory has been freed up by an unrelated application. This is on Win XP. I'm new to Windows drivers so don't know all the terminology and have hunted google for this answer without success. The PCI device is controlled with a Jungo based WinDriver and peridically the PCI device reads a few words from main memory so it knows what to do. The driver when opened has used Jungo's WD_DMALock() call to lock the pages in physical memory. All seemed to run well for 6 months until a new big application that allocates a lots of memory came along. And it is only when that big application exits that the problem occurs. It seems like a virtual memory management thing is getting in the way. Anyway, the PCI bus analyzer shows that the PCI device tries a bunch of times (currently 127 retries) to read from main memory and eventually gives up when all reads timeout. So what is going on? Thanks, Dan Olson (danole@comcast.net) Tag: 1394 async transactions Tag: 44439

    - Newbie Q : TDI driver communicating with user app? Hi, I'm totally new at this, so please forgive the basic question. I am attempting to modify a TDI filter driver so that it communicates with a user mode application to do some processing of the data. Based on the application's response, the driver will change some of the data before forwarding on the rest as usual. It seems that I can share the data with the app by making DeviceIoControl() calls to pass in a buffer to the driver to fill in and then for the app to send its response after it has completed its analysis. An article, http://www.osronline.com/article.cfm?id=108, suggested using named events created by the app to control access to shared buffers, so I attempted to incorporate that. My problem is that the driver, while it's fetching the data, can't seem to wait on a named event. However, if I stick in a KeWaitForSingleObject() within the handler for the command sent by DeviceIoControl(), it seemed OK. Does this sound like the right approach? What am I missing? Thanks for any help. V Tag: 1394 async transactions Tag: 44433

    - Change the system color I am newbie for Windows driver development. I have DDK installed in my machine. My requirement is that I want to set the system foreground color to Yellow and background to Black for all applications. Basically I want to play around with system colors. Since some of our applications override the system color using the Windows color management applet or Win32API is not an option for me. The only way is that I want to access the hardware. Please advice. thanks Tag: 1394 async transactions Tag: 44425

    - linking ZwCreateSection prevents driver loading ? Hallo everybody, I'm trying to share some memory between my wdm driver and an application using ZwCreateSection, but as soon as i use ZwCreateSection() and so bind to ntdll.lib, it will fail to load during install, returning Device not started: Device has problem: 0x27: CM_PROB_DRIVER_FAILED_LOAD I've checked a little, and it doesn't even reach the DriverEntry. Removing the mem sharing part it works fine, so I think it's some kind of problem with the import of ZwCreateSection. Am i on the right track ? How can I solve the problem ? thank you, e.

    - CIS in common memroy Does Windows occasionally access CIS on other times then at start up (power-up)? I'm interrested in this because I'm thinking of loading CIS into my 1 KB SRAM during power-up, which is the only space on the card that is used by the PC card interface. And then remove the CIS, after Windows have read all it need, to make the space avalible for registeres that is needed for the cards original function. Needs all of the 1KB space. (The PC Card have the logic that supports this replace-idea, but those Windows/ PC Card standard support it?). This implies that the CIS have to be in common memory.

    - how to match usb vid/pid with mass storage drive letter in win98 Hi I would like to find the drive letter assigned to my usb mass storage device. In win2k/xp, I can use QueryDosDevice and the SPDRP_PHYSICAL_DEVICE_OBJECT_NAME registry property to find the drive letter. But in win98, I have encountered a few problems using the same method 1. QueryDosDevice always give me back the device name. e.g.: i use "c:" as input, the function will give me back "c:". Is it a normal behaviour in win98 2. I use umss as the driver of my device so I cannot find the volume interface of my device. So how can I get the SPDRP_PHYSICAL_DEVICE_OBJECT_NAME of my device in order to compare with the returned value from QueryDosDevice 3. I do not know whether I should also use this method in win98 or not. Is there anybody who have tried this I am just a newbie. Can anybody give me some hints? Any comments and suggestions are welcome Thanks in advance Tomson Tag: 1394 async transactions Tag: 44397

    - Accessing floppy disks with 10 sectors per track Hi, I've got some old double-sided double density disks that are formatted with 10 sectors/track rather than the standard 9. Do anyone have any ideas how I could read/write these under 2000/XP? I noticed from looking at the DDK that flpydisk.sys doesn't support this layout. I was wondering whether it's possible to write some sort of simple filter driver to tell it about the extra sector per track? Just in case this is important, sector ids run 1 through 10, track numbers (in the sector headers) run 0-79 on side 0 and 128-207 on side 1. Actually, it would be really handy if I could get at the actual sector headers as well as the data... Regards, Jonathan Needle Tag: 1394 async transactions Tag: 44392

    - Question about system page table entries Hi reading about terminal server sizing I recognized the term "system page table entries" quite often. Unfortunaltey I understand the 4 GB virtual memory is devided into 2 GB users space (a private space for each process) and a 2 GB system space. Page table entries are used to map virtual memory addresses to physical ones. From my understanding, system page table entries are used to map the complete 2 GB system space to physical memory and normal PTEs describe the users space. I heard SPTEs are a limited resource and the OS is not able to use the complete 2 GB space due to this limitation If I'm wrong and SPTEs describe only portions of the system space, which portions are described? Why isn't it possible to use just PTEs I appreciate your help Stephan Tag: 1394 async transactions Tag: 44391

    - question about using VC6 with DDK Hello, i just bought Walter Oney's book on WDM drivers. so far it is really good, but i am just at page 100. at this moment i have 2 question: - in the introduction Walter says that he uses VC6 for programming and building device drivers, but i havent found am explanation so far that tells me how to set this up. is it enough to just change the compiler? and what am i supposed to enter for build target?is it enough to use the VC6 plugin or do i need to do more? - is it possible to use VC .NET 2003 instead of VC6? i still use both on my system, but i would rather move to VC .NET where possible. i am sorry if i ask questions that are answered in the book, but i have skimmed through it to see if they were, and did not find anything. i have not read the book completely, but wanted to compile an empty example to get a feel for it. rather than taking a finished example from the CD, i would build an empty driver myself so that when it is finished, i would really know what was in there. kind regards, Bruno.

    - Bluetooth HCRP credit flow Hi Folks, I am developing an HCRP firmware (Printer side HCRP profile) and testing it against the XP Bluetooth HCRP driver. I am successfully able to - have the XP host detect my device as a "HCRP Printer", - the L2CAP Control and Data channels getting created - a new printer also gets added to my "Printers and Fax" collection on the HCRP Host. Now When I try and print a document using this HCRP printer following happens: a. I get a CR_DataChannelCreditRequest on the L2CAP COntrol Channel (Printer side) to which I reply with a large number of credits (0x00 00 00 00 00 FF FF FF). b. I start recieving bytes on the L2CAP Data channel. c. After recieving 64KBytes, the Host application doesnt send any more packets. Neither any bytes on Data Channel, nor any more CR_DataChannelCreditRequest. However I recv. all the data for if the print data is less than 64K, my question is this 64K any magic number ? IMO I should be getting periodic requests for credits on the Printer side after the HCRP Host has exhausted all the credits, but no such thing happens. How has the HCRP driver in XP been implemented to handle this situation ? I have also tried sending some credtis (voluntarily) from the printer side to the Host using the CR_DataChannelCreditGrant after the 64K bytes of credit have been exhausted, but to no avail. help in any direction appreciated. thanks people for all your patience.

    - Bypass print processor Hi I have a customized print processor associated to a printer. That print processor copies the Spool files of jobs printed by users. In another application, users will take actual print outs with those spool files using the same printer. When they are actually printing, I should bypass printprocessor (Otherwise, it again copies the spool files). How to write RAW data directly to Port monitor/Printer, bypassing the print processor In my application I tried like this StartDocPrinter() StartpagePrinter() Read the spool file() WritePrinter(); // Tried printer name, Port name. Both are spooling the data.1 loop until end of file EndPagePrinter() EndDocPrinter() In the above approach, printprocessor is getting invoked. Also I tried different spooler properties like Print directly to printer. That too didn't work Is there another approach all together(My client does not want 2nd printer associated to another print processor) Thanks & Regards Kira Tag: 1394 async transactions Tag: 44374

OID_GEN_MEDIA_CONNECT_STATUS also shows connected state. But wireless properties does not show that I am connected to the AP. DHCP also does not happen. Why is this happening? Ndis goes on trying to associate with the other APs in the list, with the same result in each case. What else do I need to do to inform NDIS that the card is associated?

I have recorded card status before hibernation in the power dispatch routine. Any thing else should be done to this driver while hibernating ?such as save serial port status.

    - Encrypt/Decrypt all packets I want to write a device driver that encrypts all the packets coming from the application layer. I think it should lie between the application layer and the transport layer(TCP,UDP,etc...). Am I right I read MSDN and DDK help. But I cannot find anything for the beginners. What will I implement? Miniport? TDI? NDIS? or Can I do it in user mode just under the application layer Just guide me about what should I read for a quick start Thank Ken Tag: 1394 async transactions Tag: 44212

Is it possible to have unified write transactions. how can I set it on
microsoft windows drivers. Unified transactions will allow 1394 node
to send ACK_COMPLETE instead of "pending and write response". This
will improve performance and can get rid of response handling.

thanks.
