IOCTL_OAL_READBUSDATA	This IOCTL reads data from the bus address specified in the OAL_DDK_PARAMS structure into a buffer, which is also specified in the structure.
IOCTL_OAL_TRANSBUSADDRESS	This IOCTL translates the bus-relative address specified in the OAL_DDK_PARAMS structure to a system address, which is also specified in the structure.
IOCTL_OAL_TRANSSYSADDRESS	This IOCTL translates the system RAM address specified in the OAL_DDK_PARAMS structure to a bus-relative address, which is also specified in the structure.
