Can't get my Pioneer DR-UA124X CD-ROM to work

[Jonas]

Hello.
I installed FreeBSD for the first time a couple of days ago and
everything has worked except my CD-ROM. My CD-ROM is a Pioneer
DR-UA124X.

The CD-ROM worked with Linux and Windows 95 and it's the primary slave.
It didn't get detected during the installation. The generic kernel
couldn't find it, nor could the kernel that I compiled myself.

How do I get the CD-ROM to work?
