OpenBSD 4.8 can't find CD drive on Dell Latitude E6500

[Leslie Jensen]

Hello list.

I'm quite new to OpenBSD, have made one installation in Virtualbox plus 
an installation on a USB stick on a 32-bit pc.

Now I want to make an installation on a USB stick using the amd64 
installation CD.

The machine Dell Latitude E6500 is currently running Win7 plus FreeBSD 
8.1 in a dual boot configuration.

I removed the hard drive not to make a mistake, inserted the CD and the 
USB stick.

Installation starts, when asked how to install on the stick I those use 
the whole (w) drive.

Then comes the question of installation media and the choices are ftp 
http or done.

I can do the installation via http so I'm ok. But I am wondering how do 
I do in order to find the CD-rom drive. My plan is to install OpenBSD on 
this machine in the future.

Thanks
