I've never heard of an AD-7230S burner. But 1.D* firmware indicates that could actually be an OEM version of an existing drive. So chances are good that Binflash may detect your drive. (Win32 GUI version recommended)
If the drive is detected by Binflash but gives an error when you're trying to dump the current firmware, you should be able to create a drive identification file. If you paste the content of this file here, it might be possible to add bitsetting support for your drive.
If Binflash doesn't detect your drive at all, support for it is quite unlikely unless Lenovo provides official firmware updates.
