First, did the previous system see them both? If not, then you 
might want to check the BIOS configuration, make sure that they
aren't both jumpered as master, and so forth. They _do_ both
have power applied, open when you push the button, and so on, 
yes? That's a mistake I made last week. 

If the old system did see them both properly, and the new system 
doesn't, then does /var/run/dmesg.boot have a line for each of 
the CD drives? If it does (see example below), 

: acd0: CDROM <Pioneer CD-ROM ATAPI Model DR-744 0102> at ata1-master using PIO4

then you have a different problem, and need more help than I 
can give you. If it doesn't, then you need to track _that_ down
and correct it. Probably there will be an error message where the
system tried to determine what was there and couldn't; that may 
lead you to the cause.
