Table 2-7 lists the options and descriptions for the information fields that
appear on the Serial Communication screen.

modules, allowing data to bypass the CPU. I/OAT will be
supported on the NICs.

Assignment (Standard)
Controls the interrupt assignment of PCI devices in the
system. When set to distributed, the interrupt routing
will be swizzled to minimize IRQ sharing.
