Host System Information
This section describes the host (PC) software and hardware that you need to use OMI
2.3.1.
System Requirements
To install and use the current OMI release, the host PC must meet the following minimum
requirements:
• The PC’s PCI or AGP chip set must be compliant with the PCI 2.1 specification.
Motherboards with Intel chip sets that support Pentium/MMX or later CPUs are
known to be compliant. Cognex has not tested motherboards made with non-Intel
chip sets.
• A Windows operating system that supports the Cognex frame grabber you will use,
as described under Operating System Requirements on page 28.
• A CD-ROM drive, or access to one over a network, to install the OMI software.
• A PCI- or AGP-based video display adapter with at least 8 Megabytes of memory.
• A mouse or other pointing device supported by your Windows version.
• If using Windows 98, the runtime components of DirectX 6.0 or later.
To use OMI at its maximum potential, the host PC must meet the following additional
requirements:
• The CPU must be an Intel Pentium/MMX, Celeron, Pentium II, or Pentium III running
at 166 MHz or higher.
• The Windows desktop must be in 8-, 16-, or 32-bit color mode; the desktop must be
in 16- or 32-bit mode to display color images.
• To display full-resolution images (640x480 or larger), the Windows desktop must be
at least 800x600 pixels.
• Cognex recommends the use of an AGP video card with at least 16 MB of memory.
• The system should use bus-mastered DMA disk drivers instead of the standard PIO
drivers. Bus-mastered drivers improve system performance, as the CPU is less
heavily used during disk IO. Windows NT typically defaults to PIO drivers. Windows
98 installs the drivers but does not always enable them. Check with your
motherboard vendor to determine if it provides bus-mastered IDE drivers. For more
