System Limitations With an Optional PCIe Riser
The PCIe riser expands the number of PCIe expansion slots available in the
system to 10. Due to the limitation of 64 KB I/O address space on the Intel
IA32 architecture and the I/O granularity of 4 KB set by the PCI bridge
specification, you can exceed the maximum available I/O resources if you
populate the slots with adapters which require more than 4 KB of I/O address
space. The system does not complete POST if 64 KB I/O address space is
exceeded. For more information on supported adapters, see the Dell
PowerEdge R910 Hardware Owner's Manual at support.dell.com/manuals.
