CORB Size Capability — RO. Hardwired to 0100b indicating that the ICH7 only supports
a CORB size of 256 CORB entries (1024B).
Reserved.
CORB Size — RO. Hardwired to 10b which sets the CORB size to 256 entries (1024B).
RIRB Lower Base Address — R/W. This field is the lower address of the Response
Input Ring Buffer, allowing the RIRB base address to be assigned on any 128-B
boundary. This register field must not be written when the DMA engine is running or the
DMA transfer may be corrupted.
RIRB Lower Base Unimplemented Bits — RO. Hardwired to 0. This required the RIRB to
be allocated with 128-B granularity to allow for cache line fetch optimizations.
