are used with a conventional 3.3 or 5V PCI slot, the maximum transfer rate is
reduced (132 Mbytes/sec for a 32-bit PCI slot, 266 Mbytes/sec for a 66 MHz
32-bit PCI slot, and 532 Mbytes/sec for a 66 MHz 64-bit PCI slot).
Using the PCIe/PCI/PCI-X bus, Matrox Solios can also access Host physically
contiguous, non-paged memory. An advantage of this memory is that a bus
mastering device (such as Matrox Solios) can access this memory without the help
of the Host CPU.
