Cd Rom Drive on amiga 1200

[cyclone]

I got my amiga out a few days ago or so and forget that i had a cd drive but i could not get it to fire up the hard drive so i got a 4 gig hd 2.5 in and put it in the amiga and installed the OS 3.1 all gose fine. found the drive on the internet for my cd drive and installed them.

all working fine at this point.

so i got so 3.1 roms for it and put them in and i can not get the cd drive to work any more but as soon as i put the old roms in its fine again.

its a alfa data cd1200 controller
i even try idefix97

not sure what else to do please help :-)

ok with the version 3.0 Roms in the amiga
installed WB 3.1
then installed cd1200 floppy and at that point i can start using the cd all fine installed lots of stuf from it

recived amiga 3.1 Roms yesurday put them in and then i could no longer use the cd drive every time i look for it could not find it...
so i start looking around the internet and find that idefix may help so i download it and use the demo version for now.
still can not see the drive.

so i think ok maybe i messed something up just before i put the new 3.1 roms in.

so i format the HD and start again
install WB 3.1
start to use cd1200 disk to install but it can not see cd drive
so use idefix still can not find it

put old rom 3.0 back in and can see the cd from the start

also yes it was using idefix in the startup-sequence

i think i get a error message on boot on the 3.1 roms if i have the cd1200 drive set to lood on boot

once i have finished copy files from cd back to HD and have put back the 3.1 roms i will post the error

Thanks Ray :-)

ok i think i have found the problem

i belive its my extra memory card as i tock out the card to when i was putting the Roms in so i could get the error message i did not put the extra memory in.
the cd drive worked fine

so i thought i plug the extra memory in and then ther cd drive stoped working

i dont only have a stadard extra memory card with 8 meg on it.

weird

thanks :-?
