I/O Adapter Enlarged Capacity
You can increase the amount of I/O adapter memory for specified PCI slots.
This option controls the size of PCI memory space allocated to each PCI slots. When
enabled, selected PCI slots, including those in external I/O subsystems, receive the larger
DMA and memory mapped address space. Some PCI adapters may require this additional
DMA or memory space, per the adapter specification.
This option increases system mainstore allocation to these selected PCI slots, and enabling
this option may result in some PCI host bridges and slots not being configured because the
installed mainstore is insufficient to configure all installed PCI slots (Figure 10-49).
