Hey Ceaser,
Is it this (
http://www.amiga.org/gallery/index.php?n=1110)?If so, forget about the disk which came with the hardware - you can just install using IDEfix97, however you'll need to select "VOB" when prompted during the installation.
Dont' know why the implementaton of splitting the IDE channels is different on this particular adapter, but...
EDIT: From memory, the 44-pin connector at the top (in the picture linked to above) can be used instead of the top 40-pin connector - useful if you're adding a laptop hard drive I suppose... Also, you may want to check for burnt/broken traces - it's been a long while since I played with this bit of kit, but I vaguely remember there was a burned out trace which I needed to repair - prob. from someone connecting a cable the wrong way round at some point.
EDIT: Don't expect it to be any faster than other IDE-splitter implementations either :-/
Regards
Rich
