Device Drivers...
Need a custom device driver? We have
throughout the years developed device drivers for most of Microsoft's
operating systems. Examples of implemented drivers are Windows 98/2000/XP/Vista
USB drivers, Windows 95/98 VxD drivers, Windows 98/2000/XP/2003/Vista WDM
drivers, Windows 2000/XP printer drivers, Windows CE device drivers, NDIS
network drivers, TDI drivers etc.

Past device driver projects

Windows XP, Vista DDK, Visual Studio .NET 2003, WinDbg.
Implemented various Windows XP kernel-mode drivers
for disk encryption. Modification of the bootloader, creation of disk filter
drivers. Assembly and C reverse engineering. Documentation. Use of WinDbg and
SoftICE. Technology: C. Environment: Windows XP DDK, Visual Studio .NET 2003,
WinDbg.
Specification, design and implementation of a
TDI driver for a 10 Gbps Ethernet network card. Use of WinDbg and SoftICE.
Technology: C. Environment: Windows XP DDK, Visual Studio .NET 2003, WinDbg.
Reverse-engineering and debugging of a multi-port
serial WDM driver for Windows 2000/XP. Fixed major bugs and implemented flow
control in the driver. This was for a custom multi-purpose I/O board. Use of
WinDbg and SoftICE, Oscilloscope etc. Technology: WDM, C. Environment:
Windows XP DDK, Visual C++ 6.0, WinDbg.
Specification, design and development of a WDM
driver for a custom PCI I/O card. The I/O card contained several D/A
converters, serial EEPROM and other components that the card interfaced to via
the I2C serial interface. A driver installation script was provided for
seamless installation. The driver was designed to work on the Windows 98 / 2000
/ XP / 2003 platforms. Technology: WDM, C. Environment: Windows XP DDK, Visual
C++ 6.0, WinDbg.
Windows 9x and NT/2000 kernel mode development of
XML/SVG printer drivers. Generates an XML/SVG file that contains scalable
information that describes the printed page. The SVG file can later be viewed
using Adobe's SVG viewer or printed to an SVG compatible printer. Technology:
C. Environment: Windows 9x/2000 DDK, SoftICE.
Development of kernel mode WDM and VxD device
drivers for the Windows 95/98/98SE/2000/XP-Whistler platforms. The drivers
intercept all sounds sent via the Wave and DirectX/DirectSound APIs, applies
various 3D-sound algorithms to the sound data before sending the sound buffers
on to the sound card or USB speakers. Also developed a user mode DLL for
hooking Wave out on Windows 9x. Technology: WDM & VxD kernel mode
development in C and x86 Assembly. Environment: 95/98/W2K DDKs. 16 bit compiler
for the hook DLL.
Specification and development of a Windows
2000/XP/Whistler printer driver that generates SVG/XML-data. Contains two
COM-component plug-ins that handle rendering into the XML/SVG file respectively
defines the user settable properties of the printer driver. Technology: COM,
ATL, and C. Environment: Windows 2000 DDK, Visual C++ 6.0.
Design and development of a Windows CE printer
driver. Porting of Windows CE operating system code to a new hardware platform.
Setup of Windows CE build environment on a build server and system integration
of Windows CE to the target system. Technology: Microsoft Windows CE 2.0.
Environment: Microsoft Embedded Toolkit, C.
Development of a NT4 stream device driver in C++.
Used for generating simulated data that implements a virtual USB device.
Technology: Vireo Driver::Works class library, C++. NT DDK, C. Environment:
NT4.
Development of an USB WDM device driver for
Windows98/NT5. Used for collecting real-time data from a medical data
acquisition instrument. Technology: Microsoft DDK. C. Environment: Windows 98
and Windows 2000.
System and application programming of a Windows CE
based portable medical data acquisition device. Subprojects included: 1)
Specification and development of Windows CE device drivers for data
acquisition, 2) Windows sockets communication over infrared link (IrDa), 3)
Application programming using WIN32API, Visual C++ and MFC for Windows CE.
Environment: Windows CE, C, C++, Embedded toolkit for VC++.
Specification of Windows 95/NT device drivers and
system design of an ISDN Multimedia telephone for Windows 95/NT. DirextX
technologies like DirectShow, DirectDraw and DirectSound were used for
multimedia presentation. A video for windows (VFW) device driver was used for
interfacing the hardware with the system. A NDIS 4.0 miniport driver handled
the network communication. TAPI was used for call management. Technologies:
DirectX, VFW, NDIS miniport, TAPI. Environment: Microsoft DDK, Windows 95/NT,
C/C++.
Specification and development of a high performance
NT device driver for a PCI based fibre network card. Subprojects included: 1)
Specification and development of an NDIS 4.0 miniport. It used bus master DMA
for transferring data between main memory and the PCI Network card, 2) A LAN
emulation software was designed and implemented for interfacing NT's
connectionless TCP/IP network stack to the connection oriented DTM network.
Environment: Microsoft NT DDK. C, Windows NT 4.0.
Implementation of a Windows NT stream device driver
used to control a general-purpose parallel ISA interface board. A user mode DLL
was developed for easier access to the device driver from application programs
written in C, C++, Pascal and Visual Basic. Test applications for the targeted
programming languages were also developed. Technology: Microsoft NT DDK, C,
WIN32 API, Visual C++ and Visual Basic.
Implementation of a kernel mode audio driver for
Microsoft Windows NT. The audio board was partly Soundblaster compatible. User
mode support drivers were also developed which enabled plug-into the NT
multimedia subsystem. Technology: C, Microsoft C Compiler.
Specification and development of a Windows for
Workgroups 3.11 NDIS 3.0 miniport. The miniport controlled a NE2000 compatible
ISA network card. Installation script was also developed for the network
driver. Technology: C, Microsoft C Compiler.
