Bus Master IDE I/O Registers (D31:F5)
The bus master IDE function uses 16 bytes of I/O space, allocated via the BAR register,
located in Device 31:Function 2 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). These registers are only used for legacy
operation. Software must not use these registers when running AHCI. The description
of the I/O registers is shown in
