Scope The WDK arrives with sample code for a PCI driver, known as PCIDRV. It demonstrates the recommended old-school methods for avoiding mishaps when maintaining your own IRP queue. Frankly speaking, I’ve written this post as I learned the different corners of IRP juggling, so pretty much like certain operating systems, it’s a bit of [...]
To make a long story short… There is really no need to work hard to make your FPGA talk with a PC. Xillybus gives you the end-to-end connection interfacing FPGAs with both Linux and Windows computers. The challenge At times, FPGA engineers are faced with the need to transfer data to or from a regular [...]
The log level is set in the registry at HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Setup\LogLevel. The key may need to be created (DWORD). The default on my computer turned out to be 0x2000ff00, which means maximal logging is achieved. The set bit 29 tells the logger not to flush data into the file after each entry (faster logging, but data [...]
If you’re reading this, it’s likely that you’ve experienced a bug check (blue screen of death, BSOD, if you like) as a result of calling IoConnectInterruptEx(). It’s also likely that you used this function to support MSI (Message Signaling Interrupt). You may have attempted to follow the horribly misleading example given by Microsoft itself. The [...]
This is a short note about how to make small manipulations in executables or DLLs in order to get rid of malware behaviour. For example, if some application pops up a dialog box which I’d like to eliminate. It can also be the final step in cracking (which is very recommended as an educational experience). [...]
Linux has ltrace. Windows has…? I was looking for applications to trace DLL calls, so I could tell why a certain application goes wrong. The classic way is to get hints from library calls. Or system calls. Or both. In the beginning, I was turned down by they idea, that most trackers only support those [...]
The whole story began when I decided to be kind enough to tell the Xilinx tools (ISE 9.2 in my case) that the Virtex-4 I’m targeting is a grown-up. Stepping 2, to be precise. I added CONFIG STEPPING = “2″; to the UCF file. It must have been one of those moments where I believed [...]
Foreword Before I say a word, my children, I have to warn you: What I’m about to teach you here is basically how to mess up your computer. It’s how to make Windows install the wrong driver for a USB device (possibly PCI devices as well). Don’t complain about a headache when you want to [...]
Nothing to see here, folks… These are just some notes I wrote down for myself, in case I’ll ever want to repeat this mess. Microsoft Visual Studio 2003 was used for developing the C++ class as well as the setup project. For testing, IE 6 was used. A button running a script or executable The [...]
