Dear folks,
I had a couple of problems getting my DS1216E NoSlotClock (purchased in China) working.
Neither the downloaded version's from Asimov nor from somewhere else worked for me.
So I do found the following link which solved my problem and the clock is now working fine.
Ultimateapple 2 - DS1216E Driver
My clock is actually installed at the CD ROM position.
Hope this helps others as well
