How to make my DH-4O1S (CP56) read DVD-RAM?

I’ve flashed it with 2P53 firmware. Now programs like ImgBurn report that the drive supports DVD-RAM reading, but when I insert DVD-RAM disc (blank or recorded) the drive still can’t recognize it. Does it need some EEPROM editing to enable DVD-RAM reading?

It would be nice if somebody could dump EEPROM from DH-4O1S with working DVD-RAM reading.

Thanks in advance!
