Bus Master IDE I/O Registers (D31:F2)
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
