This register must be initialized by the configuration software. For the purpose of
address decode, address bits AD[19:0] are assumed to be zero. Thus, the bottom of
the defined memory address range will be aligned to a 1 Mbyte boundary.

Hardwired to ‘1’ to indicate that the PCI to Hub Interface
target logic is capable of receiving fast back-to-back cycles.
Hardwired to ‘0’.
Hardwired to ‘0’.
This bit is set by hardware whenever the PERR# pin is
asserted on the rising edge of PCI clock. This includes cases
in which the chipset is the agent driving PERR#. It remains
asserted until cleared by software writing a ‘1’ to this
location. When enabled by the PERR#-to-SERR# Enable bit
(in the Bridge Control register), a ‘1’ in this bit can generate
an internal SERR# and be a source for the NMI logic.
