unrecognized cdrom drive

[Tomoki Taniguchi]

i have a new laptop which i have installed feisty on.
i couldn't use the cdrom on the laptop during install for some reason
so i installed using a usb cdrom.

but now when i am on the desktop i can't get access to the cdrom on the laptop.

when i install opensuse on the same system the
cdrom is designated as /dev/hda

but /dev/hda doesn't exist on my feisty system.

Is there anyway to get my laptop's cdrom working?

-TIA
