I remember from previous SUSE Linux installations, that YaST2 usually scans all
available CD-ROM drives for installation CDs, which is quite handy for the
installation from CD - you can use both drives to insert the next installation CD.

However, this did not work for the installation of 10.0b2 - YaST2 insisted on
only reading from my CD-burner /dev/hde - CDs inserted in the DVD-ROM drive
/dev/hdd were ignored.
