I have treid to install 4.0 a couple of houers now and i cant even get the boot floppy to detect the cd

I am using a A3000T with an CSPPC and my scsi chain look like this
Term-->CSPPC-->50pin Scsi cd converted to 68pin --> 68pin HDD-->Term
The CD worked like a charm like this in 3.9 and i could transfer files and all that without a problem but when i try to boot the install with the floppy and the cd in the drive i just get "Please insert volume AmigaOS 4.0 Install CD in any drive"
Have tried varius settings in the CSPPC meny and i have chosen that the CD should be mounted.
I can see the CD drive in the Boot meny
I rly dont know what to do now. Why does everything need to be so difficult when it comes to tricking your amiga to do as you want?
