ISA-to-PCI Memory Hole Size Register (default = 00h)
Type:
Read/Write
Bit Description
:
Bit 7:
IPAHE. Memory Hole Enable. When this bit is set to "1", access to the memory hole will not be
forwarded to the PCI bus. When this bit is reset to "0", access to the hole will be forwarded to
the PCI bus. The default value of this bit after a chip reset is "0".
Bits [6:0]:
IPAHS. Memory Hole Size. This field specifies the sizes of the memory hole according to the
following list:
