 - NonStandard Floppy I want to access a nonstandard formatted floppy ( 256 bytes/sector, 16 sector/track) and the standard floppy driver don't know to read this kind of floppy. In W95 I did that with BOIS int1Eh (floppy drive parameters) and int 13h. How can I do that in NT/2000/XP? ( no BIOS interuptions access...) I begin to look the fdc example and I think that's the way ( modify the driver to know this particular format). Anybody knows other ways?If this is the solution, what and where I must change in this floppy driver example to read this format? Thanks. Tag: Identify User Tag: 41006

 - AVStream avshws DDK example I'm playing around with avshws to learn AVStream. avshws shows up in the "WDM Streaming Capture Devices" category in GraphEdit. I'd like the driver to appear in "Video Capture Sources" as well. I have some ideas as to how this might be done, but I'd like to get a deeper understanding. Any info is appreciated. AMCap only enumerates CLSID_VideoInputDeviceCategory devices, as do most capture apps that I'm aware of. What logic determines which categories a video capture card should belong to? What is the difference between CLSID_VideoInputDeviceCategory and AM_KSCATEGORY_CAPTURE? Tag: Identify User Tag: 40996

 - NEC dvd driver problem Hope I'm in the right newsgroup! I have just bought a NEC 2500 dvd rw, but have major problems installing it. WindowsXP is recognising the drive but is unable to load the drivers. The balloon message says Found New Hardware _NEC dvd rw 2500a Found New Hardware CD Rom Found New Hardware _NEC dvd rw 2500a Found New Hardware CD Rom and so on and so on. The drive is not fully recognised or usable, and is automatically disabled in the device manager. I can sometimes get XP to recognise the dvd drive by uninstalling and re-installing the dvd drivers and forcing enable and it will work fine for a while. When I re-start XP the balloon message will again pop up and it starts all over again. Found New Hardware _NEC dvd rw 2500a Found New Hardware CD Rom Found New Hardware _NEC dvd rw 2500a Found New Hardware CD Rom and on and on until I remove the drivers in Device manager. This appears to be a recognised problem and is mentioned on the NEC website but the following solution proposed by them does not work. You need to choose to your "DRIVERS" folder. Then change or delete the folder "MONITOR" Switch to "C:WINDOWS" Ensure that you have in windows explorer settings option activated to see ALL data (also hided and system files) Switch to "c:WINDOWSINF" Look for the "INFCACHE.1" file and delete it Switch to your desktop trash can and empty it If problem cant be solved, pls. contact manufacturer of your PC package. The folder "Monitor" does not exist on my PC! Any help will be gratefully received. -- --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

 - Difference between Local Disk aund Removable Disk Hi, I have read Mark Roddy's article on http://www.wd-3.com/121503/luserland.htm. He described as you can get the sector address (LBA) a file on a harddisk. His sample code works for NTFS & FAT32 partions. With a small look in the FAT spec and some adaptations the sample also works for FAT12/16. The sample works on W2K & WXP for harddisks and all disks declared as "Local Disk". For "Removable Disk" like a USB Mass Storage Device this sample (API call DeviceIoControl/IOCTL_VOLUME_LOGICAL_TO_PHYSICAL) does not work and system error 50 (not supported) does occur. The same device declared as "Local Disk" everythink does work. Is there are a workaround to get DeviceIoControl/IOCTL_VOLUME_LOGICAL_TO_PHYSICAL data also on "Removable Disks" or is there are another possibility to get the wanted information on another way? All hints are very welcome. TIA Alex Tag: Identify User Tag: 40948

I've included stdio.h and the code compiles fine, but when it links, I get "unresolved external symbol __imp__fopen referenced in function..."

 - [802.11] Windows NDIS questions Hello, I am beginner at this subject. Sorry I if ask some bullshits. I need develop an application that detect the available access points and establish a connection. The target O.S. are Windows 2000 and Windows XP. My questions are: 1. What are the diferences among NDIS, NDISUIO and NDISPROT? 2. Must I develop a Protocol driver(like NDISPROT or NDISUIO) or it's better call directly the NDIS library functions(like NdisRequest)? 3. How can I disable Wireless Zero Configuration (WZC) service inside my application? Thanks, Claudio. Tag: Identify User Tag: 40920

 - Questions on PCI config space when ressetting a PCI board Hi, I'm developing a wdm driver under Win2K for a proprietary PCI board. Unfortunately, the board's PCI interface logic is part of a FPGA that can only be fully reset by reconfiguring the FPGA. We foresee that we need to reset our board on certain occasions and we do not want to power-cycle our system for this. Therfor, I'm implementing the following reset sequence in my driver: Because the reconfiguration of the FPGA resets the PCI config space, I start with saving this data (after having disabled the boards PCI interface). I then call PoRequestPowerIrp to force the board to go to device state D3. In the IoCompletion routine, PoRequestPowerIrp is called again to force the board to go back to device state D0 (this actually resets our FPGA and the PCI config space). In the IoCompletion routine of the second PoRequestPowerIrp, I restore the PCI config space data and reenable the PCI interface. When, in the above scheme, I use the sequence IoBuildAsynchronousFsdRequest() - IoSetCompletionRoutine() - IoCallDriver() to read or write the PCI configuration space, this completion routine is called with DeviceObject = NULL. I solve this by passing the DeviceObject via the 'context' of the completion routine. Is this normal or could I be doing something wrong here? Apart from the above problem the sequence seems to work, but I am not sure wether I should also save and restore the power management registers of the PCI config space. Or should I leave this to the pci.sys bus driver who does the actual D0/D3/D0 switching ? Also, I'm not sure that the above will work under all circumstances so I would appreciate it if anybody knows where to find some more info on stuff like this. Thanks in advance, Koen Tag: Identify User Tag: 40909

 - Basic kernel mode driver question. I have the following development workstation: Windows XP Pro, VC++6.0, DDK 2600.1106 (installed in C:\DDK\WINDDK\2600.1106), Platform SDK February 2003. As a confirmation that all of the above components are installed correctly, I compiled one of the sample projects (oemps) by doing the following: 1.. Opened an XP checked build window via the start menu. 2.. Navigated to "C:\DDK\WINDDK\2600.1106\src\print\oemdll\oemps". 3.. Typed "build -cef" 4.. The kernel mode driver KOEMPS.DLL was built and placed in "C:\DDK\WINDDK\2600.1106\src\print\oemdll\i386". My goal is to generate a random number in PSCommand method of "C:\DDK\WINDDK\2600.1106\src\print\oemdll\oemps\command.cpp" 1.. Using the VC6.0 IDE, I added the following to the pscommand method: LARGE_INTEGER time; ULONG seed; // seed value should be a global or in device extension ULONG rand; // random value KeQuerySystemTime(&time); // only do first time or in init code! seed = (ULONG) time; rand = RtlRandom(&seed); // get random number 2.. I Opened an XP checked build window via the start menu. 3.. Navigated to "C:\DDK\WINDDK\2600.1106\src\print\oemdll\oemps". 4.. Typed "build -cef". Command.cpp failed to compile because KeQuerySystemTime and RtlRandom were 'undeclared identifiers'. Because these two api's are defined in ntddk.h, I added '#include <ntddk.h>' to command.cpp. The compile failed because it could not find ntddk.h. I then changed the line to '#include < C:\DDK\WINDDK\2600.1106\inc\ddk\wxp\ntddk.h>'. The compile failed again because I had several redefinition errors. How do I get api's defined in NTDDK.H to compile in this (oemps) Microsoft provided sample project? Tag: Identify User Tag: 40908

But in win 98, the lower one can't recieve that IRP. why? It seems so strange. in win98, the IoGetDeviceObjectPointer() can return success, and give a pdo to me, but I can't use it. Could anybody be kind enough to show me some light in that? Thanks in advance! Tag: Identify User Tag: 40894

 - Need Help on POSUSB Hi , I am implementing a Virtual Com port driver for our Target Device on WinXp. For this, I have taken the reference driver code from Microsoft POSUSB The issue is that while doing an install / Uninstall or Enable / Disable of the Virtual Com Port, the OS asks for a system restart. I am interested in knowing if this is an acceptable behavior as we are planning to do HCT validation of the driver. We have referred to the HCT documentation for the same, but in no place does it say that this restart is acceptable. Unfortunately, I have not been able to find how serial port emulation can be done without the above said behavior. when i Disable/Enable or Install/Uninstall the device, i am not handling the RemovalRelations in the IRP_MN_QUERY_REMOVE_DEVICE.i am just passing that IRP down as STATUS_SUCCESS. after that i am geting IRP_MN_CANCEL_REMOVE_DEVICE this is because of bus driver not process it proper. But as per Documentation you need not worry about this IRP. I would be very grateful if you can guide me in this regards. thanks in advance Regards, Deepak. Tag: Identify User Tag: 40892

 - Writing storage device driver for a flash PCI card Hello, I have a PCI adapter that has flash memory on it. I know everythings about this card, including the PCI manuf device ID, the PCI config register, and how to read and write from/to the flash memory. I want to write a driver for it such that when I open windows explorer I will see my card shown as drive D: (or E: if there is a CD rom in the system). I have been reading books, including Programming the MS WDM 2nd, Oney, and the DDK documentation from the lastest DDK for Window 2000/XP. Too much information has made me confused. 1. Should I write the SCSI mimiport driver that will layer below the scsi port driver? I read about this SCSI miniport things but it's really confused. I have thought about this but when I look at the functions that I have to implement shown in the DDK, it is too complicated. My PCI card does not use DMA and IRQ. It only need two 32-bit registers and a 4k memory range and an IO port that is part of the PCI config space. 2. What are the alternatives? Port driver? I thought my driver must be a port driver, since it must tell the system how to read and write to the PCI register. But it must contain a layer that tell the system that my drive is a D: drive. Anyhow, this whole thing is a mess in me right now. Can someone explain or show me what the best approach to this? Thank you so very much. Long Tag: Identify User Tag: 40880

 - Keyboard mouse stream separation - again... Hello folks, again I am having a few questions belonging to my previous topics. I want to separate keyboard and mouse streams originating from different devices - Windows shall only get the information of one device combo. The others shall be used for whatever. I have written adopted DDK filter driver examples for PS/2 chain. This works but is a bit dirty. The DDK also contains the original "keyboard class" and "mouse class" drivers. Wouldn´t it be possible to adopt them to deliver this feature? How are those driver examples installed? DDK help says that they are protected by system driver protection... How can you prevent XP from caring about those drivers? Many thanks for your help... Volker Tag: Identify User Tag: 40878

 - Win98 unidriver/landscape mode banding Is there anyway to get a vertical banded RGB data in Win98 unidriver ? I set sPlanes=1, sBitsPerPixel=24, thus a fnOEMDump() function is required. Unidriver bands portait pages in printing direction, that's fine. Problem raises when i print with landscape mode: If i set MD_LANDSCAPE_GRX_ABLE in fGeneral, it will band landscape page horizontally, which is not the printing direction. If i clear MD_LANDSCAPE_GRX_ABLE in fGeneral, UniControl() returns the whole page dimension at 1st time NEXTBAND was called, and returns empty rect at 2nd time NEXTBAND was called. This is absolutely not what we want. We'd like to have correct band rect(s) for landscape mode. Is there any solution for such condition in unidriver ? Or the only way is to write my own driver ?

I mean, is it possible to get such a high frequency reliable under Windows? will not my interrupts be delayed by task switching, other interrupts etc. Is it possible to disable task switching etc for a short time?

 - SPTI rejects valid requests I'm witing some low level CD access stuff (writing DAO in RAW mode and things). I'm mainly using SPTI, cos I'm developing under XP. The problem I'm having is that a number of calls are failing for no apparent reason. These calls work perfectly when I use ASPI as the transport (I choose to use ASPI or SPTI when my base level object is initialised - all the CDB construction and so on are in higher levels and identical). The 2 calls which I'm seeing give problems are Read TOC (ATIP) and ReadCD (with a -ve LBA). I've looked at the CDB and in both cases it is identical. The errors I'm seeing are Address out of Range (for Read CD) and 'invalid Operation for this track' for the ATIP reading. I cannot believe that something in Windows is doing this. But on the other hand, nor can I see anyting odd I'm doing with these particular functions. The Object proper is quite happy to use dozens of other functions (including ReadToc with other parameters!) and happily writes audio cds and DVDs and reads the same. Just these few functions ... Can ayone throw light on this? Iain Tag: Identify User Tag: 40839
