I managed to setup the dbgprint for windbg and to check for the print logs. During the warm start the system hung up when getting the OID's. And the log from the intialiaze function says "failed to connect to the FW. Timeout exceeded"
Any ideas?

Sometimes ndis throws an exception on start but you can just continue this, it isnt a BSOD stop error.

As for the FW failure it looks like you found the issue, the FW seems to fail to boot on a warm boot. Looks like you have to go back to the HW team or manufacturer and show them what you have seen.

actually it doesnt continue .. it just stalls and i need to turn off and turn on the system again. So from the "communication with FW failed error" can I surely say the problem is with FW or?

does the driver hang on to an OID for a long time? If so it should return pending and complete it later. I wouldnt expect this to hang the system though.

As for the FW yes, it is failing to respond to the driver so it looks lke an electrical/FW boot problem. Perhaps the FW crashes?

interestingly it booted once without the communication failed error. But still gives wrong MAC address. I am totally confused what's happening

There is no easy way to find out the password.
When you create a password it's hashed and saved in a table together with your username and other data.
So when you log in your tried password is hashed and this hash is compared with the saved hash. If they're equal you're allowed to login.

This hashing algorithm is as far as I know not cracked.
So the only way to find out the password is to keep trying...
That might take a while.

You would have to install a custom GINA to handle the user authentication.

Here is an open source GINA which could be modified to do what your asking:

Hi,
I am trying to tap the audio data which is going to play by the player. So i tried to use the virtual audio driver (simple) which is msvad path of WDK. I have couple of questions. Can you help me out?

1.do we have any IDE for building and debugging the kernel mode drivers for windows XP?(like visual studio for any appln)

2.What i have to implement in the copyto or copyfrom functions in the wavecyclic file? and where i have to call these functions to get the data which is going to be played?

3.do you know from where the pcm data is getting played in the audio device?

can you give me some light on this issues?

Thanks,

It is possible to setup Visual Studio to develop device drivers with full intellisense and class view. You may have to tweak a few things to get it working.

Install Debugging Tools for Windows 32-bit Version[^]

After installing WinDbg you may want to connect to VirtualPC or VMWare. I have better success with VMWare as it has greater hardware support at the moment. I'm sure Microsoft will grow into the dominate virtualization technology eventually, but they are not quite there yet.

I believe you can just RtlCopyBytes directly from the IDmaChannel buffer inside the CopyTo function into your allocated buffer. You do not need to call this CopyTo function. You will need to select your "msvad sample" as the sound playback device.

Hi David,
Thanks for your reply.
Now i could able to tap the playback data and i could able to write the data in the .wav file format using the msvad - simple virtual audio driver.I have some doubts on this.

1. Is it possible to write the PCM raw data ? By default they are writing in the .wav file format, i have changed the writeheader length as zero and i got some raw pcm data kind of thing. Is this the right way to write the raw PCM data? How i have to check the data ithat i am getting is the PCM data?

2. Is it possible to convert the attributes of PCM data which i am getting from the copyto function into my required attributes? eg,By default i am getting 44.1k sample data in the 32 bit PCM mono format. but my required attributes are 8kHz sample data 8bit or 16bit mono format. Is it possible to convert onthe fly?

3. If i want to tap the playback data from the multiple input streams(let us say , i m playing ten songs from ten separate media player) what i have to do? I tired with simple virtual audio driver by same scenario what i have given above, but i m getting the output file with mixing of all the data. what i have to do for this?

i have also tried to install the "Multstr "driver which is in msvad folder and played multiple streams, with the use of multistr driver ,but i m getting mixed playback data? can u help me out to capture the multiple playback data simultaneously?

Thanks

Hi,

I have got a Sony Vaio PCG-7A2L(VGN-FS645P)notebook, just reformatted the system and now i am badly in a need for drivers.

I have some how managed to install wireless driver and internet is working now but there is no audio drivers i can find.

I have gone through this site http://esupport.sony.com/US/perl/swu-list.pl?mdl=VGNFS645P[^]
but after installing the audio drivers, its not working.

In Device manager i am getting question mark for the following :-

Mass Storage Controller

Any help would be greatly appreciated.

Thanks a ton.

Have you installed the base packages? There's some other packages that need to be installed for the drivers to work.

From your link, I would make sure the Motherboard chipset controller and the four packages from "System Components" are installed, and the machine rebooted, before installing the drivers.

I'd start by going through each item on the Sony support site you mention, noting the manufacturer and model of each component. Then I'd go and get the latest driver for each of those components and install them, instead of the one's on the Sony site.

Cheers,
Drew.

I haveseen it so many times ...
1-first step is to install the modem driver (the sound card just installs after the modem!!!)

2- second step is to finde a HD aoudio driver of your laptop (sample aoudio drivers dosen`t work!)

Got my hands on some great NAS [modified]

After much deliberation i eventually decided on purchasing a decent NAS box for home.

Went for a QNAP TS-509 Pro, and filled it with 5 x 1.5TB drives, configured in RAID 5.

Then after i got it up and running, started reading about problems with Seagate 1.5TB drives and how they were killing RAID arrays.

Turns out all my drives were not part of the ones with the defective firmware revisions.

Breathed HUGE sigh of relief. (Looks like there is a firmware revision now available if you have affected drives, but you have to request it from seagate support directly).

Now i am going through the tedious process of ripping all my DVD's onto this thing to stream them to my TVIX media jukebox's. So far it has worked a treat.

Hi everybody
First, I'm sorry, my english is bad.

Problem:
My driver attaches "\\Device\\Video0" with IoAttachDevice() as TargetDeivce in initialization.
Then, the device driver of the display adaptor doesn't operate normally,
and the screen cannot be displayed.

My driver want to be capturing display for remote control.

I'm making on VC++6.0, and working at Windows Vista.(with Intel 82945G Express Chipset Family)

thanks in advance.

Driver to detect an interrupt (IRQ)

Hi to everybody
First, sorry for my english is so bad, I know.

I´m having a problem with the function HalGetInterruptVector and IoConnectInterrupt, my code try to be connected with the irq5. I send this to the HalGetInterruptVector function, and withoot errors I get the InterruptVector, Irql and Affinity, and with these informations I try to connect with the irq5, and the IoConnectInterrupt returns no error, but when my hardware generates an interrupt my driver does nothing.
So do you have some idea about what could be my problem?

this is the code

DeviceExtension->Level = 5;
DeviceExtension->Vector = DeviceExtension->Level;

MappedVector = HalGetInterruptVector(0,0,DeviceExtension->Level, DeviceExtension->Vector,&Irql, &DeviceExtension->Affinity);

if (MappedVector == 0)
DbgPrint("Interrupt.sys: HalGetInterruptVector failed ");

IoInitializeDpcRequest(DeviceObject,InterruptDpcRoutine);

status = IoConnectInterrupt(&DeviceExtension->InterruptObject, (PKSERVICE_ROUTINE)InterruptIsr, DeviceObject, NULL,
MappedVector,
Irql, Irql, Latched, FALSE, DeviceExtension->Affinity, FALSE);

if (!NT_SUCCESS (status))
DbgPrint("Interrupt.sys: IoConnectInterrupt Failed ");

thanks in advance,
