Dual CF adapter in A1200?

 AFAIK, using the CF cards on Amiga only works with just one CF on the IDE chain. The Amiga simply refuses to boot if a CD-ROM (marked as slave) is connected.

I once used to have external hard disk and CD-ROM drives, connected to the A1200's IDE port with a (not so) long cable, and they worked fine: hard drive as master, CD-ROM as slave.

 That's caused by differences in response time, I guess.

So please excuse me, I hadn't understood.
That is strange, must be related to the way IDE is implemented on the Amiga.
