    - HtmlHelp samples and missing definitions I've been trying everything under the sun to get "what's this" help to work via HtmlHelp and keep running into dead ends. We've tested the CHM and .txt file using eHelps TOP program to verify that everything is proper there. Yet all attempts to extract popup context sensitive "What's This" help results in a "No Topic Found" display. I am amazed at the total lack of any sample code documentation in the DDK and the MSDN site which demonstrates a successfully implementation of any HtmlHelp. If anyone knows of any samples which provides the successful implementation, I would greatly appreciate hearing on where I might find them. Then, to make matters worse, when attempting to check and see what type of error code HtmlHelp may be setting when it does fail my request, I learn that there is absolutely no definition anywhere for the HH_LAST_ERROR structure which one is supposed to use to obtain the error code. I had expected to find it in the Htmlhelp.h DDK include file with all the other macro and structure definitions, but was very surprised to learn it does not exist. Does this mean I now have to locally specify the structure, unlike all other HtmlHelp structures? Tag: Reset UDMA value for IDE drive Tag: 44619

    - [OT] Forcing 64-bit PCI Transactions Does anyone know what governs a 64-bit PCI transaction being executed vs. a 32-bit one? We have some anecdotal information about an Itanium motherboard that would only start doing 64-bit transactions when the PCI bridge (Northbridge) FIFO reached a certain point. This despite the processor doing 64-bit transactions on it's local bus. And yes, the PCI bus was a 64-bit bus. These folks had a custom 64-bit card that was also a bus master. When their card took control of the bus, the transactions were all 64-bit and the processor handled them accordingly. Is the PCI transaction size governed by the OS (settings or device driver)? Hardware setup (presumably via the BIOS)? Or is it governed (and limited) by the functionality of the PCI bridge hardware. Any ideas, pointers to references, comments, etc will be greatly appreciated! Thanks!! Don Tag: Reset UDMA value for IDE drive Tag: 44614

    - Terminating threads at protocol unload time (NDIS) Greetings! I call the following function from my NDIS protocol unload handler: APIRET Cleanup(VOID) { NTSTATUS status; LARGE_INTEGER liTimeout; SignalEvent(hTerminateThread); // // In NT kernel mode, we must wait for the thread // itself to terminate. Otherwise we will unload // while the thread is still active. => KABOOM! // PAGED_CODE(); ASSERT(hThread != 0); liTimeout.QuadPart = -10000000LL; // Wait one second status = KeWaitForSingleObject(hThread, Executive, KernelMode, FALSE, &liTimeout); // Close handle, we'll not be using it anymore. ZwClose(hThread); hThread = 0; DestroyHashTable(hHashTable); return APIRET_OK; } This results in an IRQL_NOT_LESS_OR_EQUAL exception with the following params: Arg1: 80000548, memory referenced Arg2: 00000002, IRQL Arg3: 00000000, value 0 = read operation, 1 = write operation Arg4: 804ea528, address which referenced memory READ_ADDRESS: 80000548 CURRENT_IRQL: 2 FAULTING_IP: nt!KeWaitForSingleObject+b9 804ea528 803b02 cmp byte ptr [ebx],0x2 Which I find a bit puzzling. The "Memory referenced" argument is the same as the value of hThread. hThread was created at the init of the driver by PsCreateThread. As you can see, both the PAGED_CODE() macro and the ASSERT for checking the thread handle is passed successfully. This is on a plain Windows XP Professional GA with no fixes btw... Just to have a clean test environment. Is there any other preferred way to do this, or any obvious mistakes that I've done with regards to KeWaitForSingleObject? I have tried not waiting too, but that traps when the sleeping thread wakes up after the driver image has been unloaded... :/ Take Care! Harald Eilertsen!

    - GSM Modem Hi we developing a driver for a USB GSM modem on Windows XP and 2000. The Pnp inf file initialise the unimodem driver. To have different configurations we use the following entries in the INF file HKR, Protocol\GSM\GPRS, 1,, "AT<cr> HKR, Protocol\GSM\ANALOG_RLP,1,, "AT+CBST=7,,1<cr>" ; or ATB1 HKR, Protocol\GSM\ANALOG_RLP_14DOT4K,1,, "AT+CBST=14,,1<cr>" ; or ATB1 HKR, Protocol\GSM\V110_4DOT8K,1,, "AT+CBST=70,,1<cr>" ; or ATB2 HKR, Protocol\GSM\V110_9DOT6K,1,, "AT+CBST=71,,1<cr>" ; or ATB2 HKR, Protocol\GSM\V110_14DOT4K,1,, "AT+CBST=75,,1<cr>" ; or ATB3 The installation works fine. I see the selection "GPRS","ANALOG_RLP", ... on two places 1.) ControlPanel->Phone and Modem Options ->Modems->Properties->Advanced->Change Default Preferences->DataProtoco and on Dialup Connection->Properties->General->Configure->Modem Protoco If both setting does not point to the same protocol the default setting is used. I think this is a bad solution for the user. It could prepare two or more dial up solution to connect to several providers or servers. Maybe each provider server needs a different protocol. So the user must change the default settings under the control panel to activate a different connection Do I anything wrong? Can I get a hint to improve my driver? Or can anybody confirm this behaviour of Windows Thank you Guenter Hildebrandt Tag: Reset UDMA value for IDE drive Tag: 44601

    - Request not coming to TDI filter Hi, I am developing TDI filter driver for VPN client.In my driver I handle both TCP and UDP request which is coming from the user mode application. Now my problem is with Network file shared/ Mapped files/Drive,while accessing this the filesystem will send this request to network redirector. So windows uses "NetBt" if this is the case, then all the request of this "NetBt" should come to tdi filter driver.But I didn't get any request in the filter driver while accessing the network shared files/drive.

    - [ANN]: Packet Sniffer SDK version 2.1 is released Greetings, We are pleased to announce version 2.1 of Packet Sniffer SDK, the Gigabit compatible packet capture library set for Windows networks. What's new in version 2.1: [+] FastBPF technology (BPF Just-In-Time compilation) is implemented in the HNUserFilter object of Packet Sniffer SDK. Now, when you set user-defined BPF filtering program by HNUserFilter object, HNUserFilter compiles BPF in a 32-bit optimized CPU code, which works on the level of the PSSDK built-in packet capture driver. Further traffic filtering is processed by this precompiled BPF program. With FastBPF technology Packet Sniffer SDK works approximately 6 times faster than with classic filtering by BPF virtual machine. [+] Windows 95/98/ME support added.

    - Device Manager and devcon do not remove driver service entries for PNP drivers on uninstall It seems that the Device manager and devcon.exe do not actually remove the service associated with a driver when uninstalling a device from the system. Additionally, it does not look like the SetupDi... api supports this functionality. Both tools are properly removing device instances in my case, but the service entries are left behind in the registry, and the driver binary files are left on the system. This happens on both XP and W2K3. Looking through the docs there doesn't seem to be a PNP way to remove them. DeleteService() and manual delete of the binaries seems to be the only way to get everything off the system. There is an api to remove OEM .inf and .pnf files, but not a driver service or binaries. Is this on purpose, or was this an accidental omission from the PNP install support? Is this going to be a problem in WHQL validation of a driver package? Is there something I'm missing?

    - software raid0/striping on C: ? My topic here is to discuss why microsoft does not implement the ability to utilize at OS-Setup two disks as raid0/striping. Yes I know, raid0 is not safe, or at least is just as safe a a 1-disk which is the most popular solution for 99% of the users in the desktop computing. So why after all not allowing this ??? I think users should be allowed doing this, assuming the risks on their own. the fact of the matter is that nowadays everybody may afford a couple of hard drives and if put on different IDE channels/perhaps controllers they could 'fly' with raid0. This limitation indeed exixts within the Redhat/Fedora implementations too as well as others, but just because of 'lack of care' for those requirements that many users would appreciate instead if given the chance. Slackware Linux on the other hand SHOWS that it is possible to in fact have two separate devices paired as raid0 mounted on / (equivalent to c:) This raid0/striping on boot/root is way possible, I am a linux guru too, although I love and prefer Microsoft, and since it's possible because I made it and used it, I am wondering if this limitation is made perhaps because the microsoft's disk structure/software could not handle this at all unlike linux.

    - Legacy driver "cannot find the device specified" Hi All - First my apologies I am not a driver developer, but I hope some of the experts on this group can help! I have an XP machine on which the Microsoft userdump utility fails to install. The problem appears to relate to userdump.sys, installed as a legacy kernel mode driver. This will not start, and on boot-up or attempting to start (via the service userdump.exe which depends on it) SCM logs "The system cannot find the device specified". sc query udmpdrvr shows it stopped with WIN32_EXIT_CODE 20, which I think means the same. During an attempt to start it, Regmon shows an enum\root subkey LEGACY_UDMPDRVR being created by Services.exe, but it is then promptly deleted again. Can anyone please suggest ways of troubleshooting this issue, or suggest what might be going wrong? Thanks in advance - Mike. Tag: Reset UDMA value for IDE drive Tag: 44515

    - [XP] disk class filter & FAT32 Hi, I recently wrote a disk class upper filter driver. It starts at boot time! The very strange problem is that it is somehow dependent on the file system of the host system. case 1: WinXP is on a NTFS partition -> no problems at all case 2: WinXP is on a FAT32 partition -> I get 0x0000007b meaning INACCESSIBLE_BOOT_DEVICE. Since the filter only acts on disk class devices it shouldn't depend on the filesystem, right? Any ideas about that? regards M.O. Tag: Reset UDMA value for IDE drive Tag: 44514

    - disk compression? guys, I want to understand how the transparent disk compression works, I already know it works as a compression layer between the OS and the cluster/sector access. but I am confused, even if a cluster or chunk or block can be shrunk into less than its original size, there will be unused parts and the end in such a unit. the compression would be effective only if those unused units are reutilized somehow, but how ? I don't get it. please help me out Tag: Reset UDMA value for IDE drive Tag: 44494

    - Dot Matrix Printers and XP I have an application which prints invoices to an Okidata ML 590 on XP. After the print job is complete, the printer doesn't advance the paper to the correct position of the next page I've printed a test page from the print server configuration and found the test page doesn't advance to the correct position. I've also found that MS Word and Notepad also do not advance correctly. The printer (when pressing the FF button) advances the page correctly The Okidata site doesn't offer a driver for XP and says the only driver available is in XP I've also found the above issue is happening when using a Panasonic impact printer Any ideas or suggestions Thanks for any help Tag: Reset UDMA value for IDE drive Tag: 44485

    - [newbie] invalid pointer value in kernel mode Hi some newbie problem. I'm using a linked list in kernel mode and a loop to walk through it. Now, I need a statement that causes a break of the loop - in this case, an invalid pointer value test = head; //head is -guess what- head of the linked lis for(;test->Next != ??;test = test->Next //do somethin The thing I'm looking for is a replacement for ??. I've tried NULL, but this ends up in an immortal loop (I guess all bits in the pointer test->Next are set to 1). Is there a statement that reflects the 'default' value of a pointer, when it wasn't initialized at all Thank Sam Tag: Reset UDMA value for IDE drive Tag: 44473

Is it as soon a restart/shutdown har been issued or when windows think it's time to close my driver ? 3: Can I gen a notification as soon an system restart/shutdown has bee issued ?

    - inter driver communication ? hi how do you call one driver's functions from another ? I searched the archives but the threads i found talked only about communications among drivers lying on the same stack. If i have to route packets coming to the NIC to some other PCI device so that it can process them, how do i call that PCI device's driver's functions and pass them the packet data so that it can process them and then return them back and i can pass them over to the NIC. I am using the DDK's sample "NDIS passthru intermediate driver" for hooking the packets and now want to call the other PCI card's functions to process those packets before sending them over i dont know much about drivers. is there a way i can get the other driver's handle from the kernel and call its funcitons any help will be appreciated. and since i am a novice therefore details are welcome taj.

    - 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?
