Hi all,
I am new in the forum…
I recently adquired a LiteON LTR-40125S with
the latest firmware ZSON!!
And would like to know what for are the 4 PINS
near the audio-cable (on rear of the liteOn
CDRW drive). Someone tell me that this are
jumpers to activate the DMA or UltraDMA, but
I am nor sure? Anyone knows…
I also would like to know if someone on the forum
recomend to upgrade the ZSON firmware to some
other version or to overclock the drive?
Thanks in advanced,
Bosco.
Disregard the pins. UDMA is enabled by default.
The firmware you have is fine.
Overclocking is up to you. The drive will work just fine as it is.

Absolutely ! 
An excellent answer .
DMA is on by default, but sometimes set to PIO. You can check it by going into device manager and check under either primary or secondary IDE controller, depending on where you connected the Lite-On. Them pins you see on the back is used to set Master, Slave, or Cable select for the drive.
For the LTR-40125S, flash w/ VS08 for LTR-48125W. Use mtkflash in DOS for the process. You can get the files mentioned here. Make sure you read the mtkflash readme and no CD is in the Lite-On before you flash. Good luck.

And you would check in Nero Info Tool -> Configuration whether DMA is ON or OFF.
