Active terminators usually have a voltage regulator, where passive
terminators are just resistors or resistor-packs.

Some boards implement auto-detection, e.g. with the aic7xxx series
it doesn't work: you should always set the right termination in the BIOS.

Autodetection seems to work quite well with the Tekram DC-390F (875
and 896 based). As I told you, with the board I have, you disable or
enable termination through a jumper. I have it disabled, and thus
I have now an external terminator (I use the internal bus, and the
external bus from time to time).

An active terminator has nothing to do with auto-detection.

What I am afraid of is that it may not fix your problem.

Could you double check first (you may need to open the CD-ROM external
box) that the CD-ROM drive doesn't already have termination on, and that
it HAS termination power on ?

Double-termination can also create problems.
