I can not boot MorphOS 2.0 from CD on my Peg 2 G3!

It seems that my second IDE channel is lost when boot.img
2.0 is loaded. In early startup menu there is no CD in the list and boot with no startup-sequence shows no CD with shell command "info".

My 1.4.5 setup shows in UnitControl:
Unit 0 Samsung SV 1203N
Unit 2 DVDRAM GSA-4163BA 106
Unit 3 IDE CARD READER 9350 1

Something wrong with the IDE recognition?
Later I want to try without the IDE CARD READER.

Thanks for help
