GSA-T10N TM02 Firmware IDE Mode

In post #2 of thread , ala42 posted a link to a location for acquisition of LG GSA-T10N TM02 firmware.

ala42 also posted a warning about whether the firmware is for IDE Master, IDE Slave, Cable Select, or generic being unclear.

Is the status of the IDE mode for TM02 firmware still unclear? What IDE mode (if any) does the firmware use?
