    - Windows 2003 Server compatibiliy Hi, I figure this is the write group to ask this sort of question. I am trying to determine general device driver compatibility with Windows 2003 Server. Sepcifically if a hardwar has a Windows XP or Windows 2000 driver will it be compatible with Windows 2003 Server. I have looked for info but have not been able to find a specifc specification or standard that seperated 2003 drivers from their XP or Win2k counterparts. Could somebody please clarify this for me. Thanks, Ward. Tag: access the harddisk bitwise Tag: 47321

    - UMSS for win 98 Hi,All: I used Microsoft release UMSS source code to develop our USB mass storage driver for windows 98. I found that When AEP_DEVICE_INQUIRY is received, I create IOP and submit ILB request to call my WDM driver. Normally the ILB request will wait until my calldown complete routine is complete, then I free the IOP. But sometimes the ILB request will complete after calling my WDM driver(my WDM driver don't issus complete). When my calldown complete routine is complete, the system hang. Because the IOP is free. Does Anyone know what happen? Gil Source code: ((PISP)&IOPCreateISP)->ISP_func = ISP_CREATE_IOP; IOPCreateISP.ISP_IOP_size = IOPLength; IOPCreateISP.ISP_delta_to_ior = (ULONG)&(((pIOP)0L)->IOP_ior); IOPCreateISP.ISP_i_c_flags = ISP_M_FL_MUST_SUCCEED; // Call IOS ILBService(&IOPCreateISP); // // Build our I/O request // // Call IOS to fill in SG descriptors, etc. ILBCriteria(Iop); // Submit request to IOS ILBRequest(Iop, Dcb); // Free our IOP ((PISP)&AllocISP)->ISP_func = ISP_DEALLOC_MEM; ((PISP_mem_dealloc)&AllocISP)->ISP_mem_ptr_da = (ULONG)Iop; ((ILB_internal_request_func)(UMSSPDR_Ilb.ILB_service_rtn))((PISP)&AllocISP); Tag: access the harddisk bitwise Tag: 47315

    - SetPrinterData Dears, I'm building cosumized dll using unidrv model (oemdll example). I used SetPrinterData and GetPrinterData in the UI dll it worked fine, GetPrinterData also worked fine in the customizaion dll of the graphics engine. I'm faceing a problem I tried to use SetPrinterData, or EngSetPrinterData, both return code 5, i guess this means access violation. the code is: dwResult = SetPrinterData(pdev->hPrinter, STDSTR_FONTDATASIZE, REG_DWORD, (PBYTE) &FontSize, sizeof(DWORD)); where FontSize is a DWORD and STDSTR_FONTDATASIZE is defined as follows: #define STDSTR_FONTDATASIZE TEXT("FontDataSize") hPrinter is stored when the driver received the EnablePDEV call, and it worked in GetPrinterData. Please if any body knows what is going around please advise. Best regards, -Amer Malas. Tag: access the harddisk bitwise Tag: 47314

    - windows = realtime? Hello, I have posted similar topic some weeks ago and now I want to discuss it further. I'm searching for operating system to meet real-time constraints. I know that windows is not true real time system, but I have found some papers complaining that Windows NT can be used as real time system. It complains that total interrupt latency of NT is about 30 microseconds. That sounds good for me. I found nothing about Win 2000 and XP interrupt latency. Maybe someone knows? I think if I write my apps in Ring0 as kernel mode drivers, then I will have latency as system interrupt latency. So why Windows cant be used as real-time system? Maybe someone have good ideas or links about that. I found it very interesting topic. I have searched through internet and found lots of add-on for linux kernels, but they can guarantee about 30 microseconds latency. Developers complain that these add-ons is real time. So why windows with 30 us latency can't be real time? Thank you for any thoughts. alpha Tag: access the harddisk bitwise Tag: 47307

    - Driver error (I am a newbie at this) I used the function ZwCreateFile in a keyboard driver source code (C language). The DDK linked it well but when I install the driver, reboot and press a key (in the source code I wrote to do ZwCreateFile when I press a key) There is a black screen for about half a second and then it reboots again. I debugged it and now I know that it happens exactly in the ZwCreateFile. When I linked the same source to a normal EXE file the open worked well and there were no runtimes. What it the problem? Can't I use ZwCreateFile in a driver? Wrong parameters maybe? Tag: access the harddisk bitwise Tag: 47301

    - memory backed files I want to write to a memory backed file. I create a file - I create a section with the file handle I open a view on the section. Question: It appears that once I've got a section, I just write to the mapped section. Then I close everything up and viola, stuff just shows up on the disk when the MM is done having its way with it. Fine, how big is the file ? There is a MaximumSize arg to ZwCreateSection, and a flag SECTION_EXTEND_SIZE. But how do I guess at a size, then if turns out I did not need so much memory, how do I shrink it down? And conversely, If I need more, how do I grow it? Thanks -- Gak Tag: access the harddisk bitwise Tag: 47286

    - SilentInstall Hi We have developped a device driver stack that "mounts" removable storage. When a new volume is detected by PnP manager, the system ask for one of our drivers (the one actually creating the disk objects), even is this driver has already been installed in the system. We have then to provide the path to this driver file, and this is somewhat annoying. We want to avoid this behavior. In our DispatchPnp routines, we set the SilentInstall capabilities this way: case IRP_MN_QUERY_CAPABILITIES: { PDEVICE_CAPABILITIES capabilities; capabilities = irpSp->Parameters.DeviceCapabilities.Capabilities; capabilities->SilentInstall = 1; ... ntStatus = STATUS_SUCCESS; break; } Our drivers are not digitally signed and won't be for a long time. What can be done to avoid that the system asks for the driver file, that has actually already been installed ? TIA VV Tag: access the harddisk bitwise Tag: 47264

    - printer driver signing Hello, Does driver signing requires the driver to be associated with hardware device. For e.g:- If I have a printer driver which acts as a format convertor(lets say converts to .doc format), how can I get this driver signed? I feel it is possible to have computer policies which restrict installation of drivers which aren't digitally signed. So I would prefer to get them signed. Any insights here with the above case.

    - decrypt WPA group key Hi, This probably isn't the best newsgroup for this question, but probably the ones knowing the answer can be found here :) During WPA group key handshake using TKIP I will recieve a key encrypted with RC4 I have used OpenSSL to decrypt and that works fine, but I would like to use CryptoAPI. This is how I have done it with OpenSSL void DecryptGTK(unsigned char *pIV, unsigned char *pKEK, unsigned char *pData, unsigned char *pRet) { unsigned char keys[32]; memcpy(keys, pIV, 16); memcpy(&keys[16], pKEK, 16); RC4_KEY key; RC4_set_key(&key,32, (const unsigned char *)&keys); unsigned char tempin[256]; /* Temporary input (discard) */ unsigned char tempout[256]; /* Temporary output (discard) */ RC4(&key, 256, tempin, tempout); /* Step 256 times */ RC4(&key,32,pData,pRet); } now I started to implement the CryptoAPI, but right now I can't make sense out of it. DWORD dwCryptoPasswordLength; DWORD dwDataValueLength; HKEY hKeyResult; HCRYPTPROV hCryptoProvider; HCRYPTKEY hCryptoKey; HCRYPTHASH hHash; if(!CryptAcquireContext( &hCryptoProvider, NULL, NULL, PROV_RSA_FULL, 0)) { printf("!CryptAcquireContext"); } if(!CryptCreateHash(hCryptoProvider, CALG_MD5, 0, 0, &hHash)) { printf("!CryptCreateHash"); } dwCryptoPasswordLength = 16; if(!CryptHashData(hHash, (LPBYTE)pKEK, dwCryptoPasswordLength, 0)) { printf("!CryptHashData"); } if(!CryptDeriveKey(hCryptoProvider, CALG_RC4, hHash, CRYPT_EXPORTABLE, &hCryptoKey)) { printf("!CryptDeriveKey"); } if(!CryptSetKeyParam(hCryptoKey, KP_IV, pIV, 0)) { printf("\nCryptSetKeyParam\n"); } dwDataValueLength = 32; DWORD dwBuff = 32; if(!CryptDecrypt(hCryptoKey, 0, TRUE, 0, pData, &dwDataValueLength)) { printf("!CryptDecrypt"); } any ideas how this should actually be solved? /thanks Tag: access the harddisk bitwise Tag: 47219

    - Terminal server and windows 2000 Printer driver Hello, Can someone explain me this behaviour:- 1) Installed my printer driver on machine A locally on 2000 terminal server. 2) Connect to machine A from a 2000 professional machine "vipin" using remote desktop connection and login as USER1(this is in administrative groups) 3) Connect again to machine A from 2000 professional machine but with login USER2(Administrative group rights) Observation:- Each time I connect, I see a new printer getting created of the form printername\vipin\session0 printername\vipin\session1 .... and makes it the default for the session. Everytime I logoff the session, the correspomnding session instance gets deleted. It would have been fine if there were one session instance viewable in the session's printer folder, printer session instances of all the sessions to the Terminal server are visible. In addition there is a printer of the form "printername". These are viewable also when you log as a user on the Terminal server itself. So I installed the Microsoft drivers(one's that come with the operating system using Add Printer), I make connections, I don't see the behaviour. Can someone tell me whats causing this behaviour? thanks vipin Tag: access the harddisk bitwise Tag: 47210

    - "The file or directory is corrupted and unreadable" during installation of a PnP printer device. Hi All, I have a strange problem with a Printer INF file that I don't know how to resolve... I have created an INF file through MS genINF tool. The printers included in the INF file support serial, parallel (IEEE 1284) and USB interfaces and as you may suppose the parallel and USB interfaces support PnP. The file in my opinion is a correct one and when I install the driver without "Automatic Windows detection wizard" but with manually choosing the Printer port and driver location all the things work fine. The installation wizard copies the driver files successfully to windows driver directory. However during the driver installation for automatically discovered PnP printer (for example with USB interface) when I choose "Specify a location" in "Locate Driver Files" dialog page and after that "Next" Windows locate my INF file as a correct driver INF file but when I press "Next" button the following message appears in the next dialog page: "An error occurred during the installation of the device. The file or directory is corrupted and unreadable.". I have tried the mentioned procedure on 3 different machines and always get the same result (Windows 2000 SP4). That is why I suppose that the problem is not with the directory but with the INF file. Can someone help with this ? 10x in advance! ___________________________________________ Best regards, Ivan Dimitrov Tag: access the harddisk bitwise Tag: 47201

    - Help! layered drivers lead to Blue Screen Dear All, I develop a layered driver for a usb token including 3 part. Enum.sys -> VR.sys -> key.sys Enum.sys is a enumerator to enum key, VR.sys is the driver for virtual smart card reader and key.sys is the driver for the key. Now, I meet a problem, I write a PC/SC application to send APDU sequentially to my token, but some time when I surprisedly remove the token, the system will crash and show there is a 0x000000ce fatal system error in VR.sys. That means there is an operation not cancel in VR.sys when key.sys unload. I think may be when the token removed, the VR will delay to get the message and the application still send IRP to VR.sys, so it will cause system crash. Is that right? And who can help me to get the solution to this problem. Thank you very much! Best Regards! Tag: access the harddisk bitwise Tag: 47196

    - Multiport Serial I am writing a kernel mode driver for a PCI card with 16 serial ports. It is a WDM style driver, and in my INF file I've made the class "Multiport Serial" (GUID 50906cb8-ba12-11d1-bf5d-0000f805f530). The driver archetecure is based on the multifunction example in Walter Oney's 2nd edition WDM book. In the AddDevice routine for the child part of the driver, I'm calling IoRegisterDeviceInterface, using the GUID that the serial driver uses for the same call (86e0d1e0-8089-11d0-9ce408003e301f73). None of the 16 child devices seem to appear to the system as serial ports. Hyperterminal does not recognize them. Although the Device Manager shows a Multiport Serial entry, with the 16 devices (and the controller/parent device, which I really don't want users to see), it does not list them under Serial Ports. What exactly does "Multi Port Serial" mean to Microsoft? If not RS232 type serial, then what was the intention? Does anyone have any ideas on how I can let the system know that my devices are serial devices? Tag: access the harddisk bitwise Tag: 47189

If you would like to help please reply to infoz@edenspeace.com. Also I'm kind of burned out so I'm not able to do anything really challenging at the moment. Description of the project below. Thanks, Tim ------------------ The immediate problem: At www.reago.com click on MouseHead. I have a user mode continuous AV recorder however as soon as I stress the system with the audio/video comprehension, wdmaud and video are locking up in terminal loops inside of the kernel drivers. I may need to move down to a kernel mode driver. ------------------ The larger project: A collaborative project for generalize data comprehension and responsive feedback is forming from work I have done over the past 10 to 15 years; resulting in part in a signal processing data abstraction engine. The goal is to provide human-like interactive conversational access to a distributed human knowledge network. And on local machines, instead of reading books, to provide a conversational interface. Florida Institute of Technology is interested Virginia Tech Human Interface Lab is interested TC Williams, a tech savvy high school is interested A pipeline of software releases has begun at mi web site http://www.reago.com leading up to ai-Books and ai-Mentor. The first release is a web cam controlled mouse, MouseHead. The business plan is simple. Give away the products and ask for donations. If necessary, charge for spin-off services and products. These products represent an enormous effort on mi part. Substantial innovative technology. How to grow beyond a one man project is the challenge. International University associations seem likely to be one of the best solutions. To date outside of the US the following countries have produced the most hits on the web site, in this order: Belgium, Switzerland, Australia, Hungary, Netherlands, Brazil, Germany, South Africa, Poland, Italy, Lithuania, Israel, Sweden, Norway, Argentina, plus about 50 more countries. I have contacted professors at two of the universities in Switzerland with related high-tech development departments and I will contact compatible universities in these other countries from the top of this list to extend the collaboration. Hopefully gathering together a developer or two from each university. Two private access discussion forums are set up at www.edenspeace.com/groups. ai-Books for development and NSP for architecture. More will be added as needed. Thousands of pages of existing source code were developed using Borland C++ Builder v5. I am presently considering a switch to the following cross-platform open source building blocks for the visualization and maintenance interface: OpenGL, foundation 3D libraries OpenSceneGraph, 3D scene visualization and construction OpenProducer, 3D camera control BlueMarbleViewer, large scale data paging and region zoom wxWidgets and wxGLCanvas, OpenGL compatible O/S windows wrapper GCC compiler OpenThreads, cross-platform multi-threading interface Features extracted from CVS version control for multi-developer support Also: Custom server and network visualization and maintenance environment Custom applications and server layers The NSP core network architecture recently finished a full review by a uspto primary examiner, no conflicts found. Specifically with reference to AT&T research labs one of the problems yet solved is the visualization and editing of massive continuously evolving data networks, including real-time changes, and probably best displayed in 3D. Formerly I handled this on a 2D flow-graph basis which is insufficient for the large volumes of data associated with the neural comprehension engine. Does AT&T have any interest in this project? Having read the various project you all are working on, I know there is compatibility. Specifically with reference to OSR one of the problems yet solved is industrial strength continuous audio/video recording. Thus far audio/video recording in user mode is not working too well, having tried as many combinations of possibilities as I can imagine. The project presently has zero budget.

    - DEVMODE in DrvDocumentPropertySheets ??? Does anybody know why the DrvDocumentPropertySheets() is called with a completely blank DEVMODE structure and both the DM_IN_BUFFER and DM_OUT_BUFFER flag set ?? According to the DDK this DEVMODE should be copied into the drivers internal DEVMODE (overwriting my default DEVMODE values), but afterwards this blank DEVMODE (now my internal DEVMODE) seems to follow me anywhere in subsequent program execution??

    - intermediate driver link rate reporting I have implemented an intermediate driver for Win2K with tapi support. The link rate indicated in the dialer is not right. The rate given at the time of installation( as a response to tapi calls) is always taken, & the rate given later is not taken and shown by the dialer. This seems to be an inherenet problem with intermediate drivers with tapi. Anybody faced such a problem, and any ideas how this can be fixed? Anand. Tag: access the harddisk bitwise Tag: 47168

    - Printer Status I modified the language monitor to work with our custom made printer (from the WDDK). Whenever and error occurs on the printer (door open, paper out..) I can see the status in the printer & Faxes window but it doesn't show any status when I go in the printer queue window. What should I do to see the message in there? -- Oreo Tag: access the harddisk bitwise Tag: 47148

    - Assertion in AMD cross-compiler Hi All, Apparently my post to news:microsoft.public.dotnet.languages.vc about some assertion failed in AMD64 cross-compiler got ingnored, but I can't compile our product for Amd64 platfom without this bug fixed. Is there any more relevant group/mail-address where I could post my question about the problem with Visual C++/Amd64 cross compiler (that from DDK 3790)?

    - Passthru problems at Distpatch_Level Hi, I am using the NDIS IM Passthru driver. I have to redirect the packets to another (Target) driver for processing. I did it by sending IRPs from MPSend and PtReceive functions. User mode applications will also be accessing that Target driver. I used Mutexes to enforce mutual exclusion in access to resources in that driver. However I soon got Bug Checks and Page Faults. The reason was that MPSend often was called at DISPATCH_LEVEL and waiting for mutex at IRQL=2 caused those errors. The question is why MPSend is called at DISPATCH_LEVEL ? Is there any way to avoid it ? If not, can I wait (for the mutex) at DISPATCH_LEVEL ? (I searched the internet and have concluded that I cannot ). If also not, what should the ioctl handler of the Target Driver do if it gets the IRP containing the packet from MPSend and the mutex is not available. I cannot queue the IRP and return status_pending because that would also mean waiting in MPSend at Dispatch_Level ? any help from anybody would be appreciated. thank you.

    - Legacy driver WHQL signing I'm interesting in WHQL signing of legacy driver, which acts as kernel extension for process that uses this driver. Is it possible? Thanks for assistance. Tag: access the harddisk bitwise Tag: 47113

Hi

I'd like to read and write directly from/toto a harddisk. What type of
driver do I need here? So what I want is to access the disk like e.g.
PartitionMagic does... any ideas how to do this? (I don't think it's
possible without driver... or am I wrong?)

thanks
MR

Open the file named \\.\PhysicalDrive0 or \\.\PhysicalDrive1 or such.

:-) easier than I thought... I also found some code about this (ok...
pascal... but anyway) ... thanks
