Hi guys,
I have an ACER X1700 (bought a month ago) and it came with this ATAPI DVD A DH16A6S SCSI drive, with YA16 firmware and LABELFLASH function.
I found that it has a minimum writing speed of 4x and for some applications and media I need it to be able to write at 1x speed.
I extracted the firmware with Flash Utility 3.0.3 in order to change it with Omni Patcher 2.6.2, but this application does not seem to recognise the extracted firmware. I also extracted the EEPROM with EEPROM Utility 5.0.1.
Can someone tell me the way to make the change I need? Shall I make a crossflashing to a difefrent firmware than the stock one? Which one? How? As I am a newbie in DVD-RW flashing I am afraid if bricking my DVD-RW unit. 
By the way, the DVD-RW unit does not have any LED to be aware of a missflashing.
Thank you very much!!
