What is the benefit of Universal PCI support with MXI-4?
With Universal PCI support, MXI-4 now can be used in more types of PCI

boards like MXI-4 by slowing down the bus to 33 Mhz operation.
What is significant about improved error handling with MXI-4?
MXI-4 now offers the flexibility to correct for serial data corruption during
transmission in noisy or harsh environments. MXI-4 also gives greater
flexibility of use.
