Table 158. Bus Master IDE I/O Register Address Map
Bus Master IDE I/O Registers (D31:F2)
The bus master IDE function uses 16 bytes of I/O space, allocated via the BMIBA register, located
in Device 31:Function 1 Configuration space, offset 20h. All bus master IDE I/O space registers
can be accessed as byte, word, or DWord quantities. Reading reserved bits returns an
indeterminate, inconsistent value, and writes to reserved bits have no affect (but should not be
attempted). The description of the I/O registers is shown in
