My problem is that i cannot mount cdrom device. It's a SONY CD-ROM CDU5221 (as you can see above).
I tried the ordinary way :
#mount -t cd9660 -o ro /dev/cd0a /mnt
and 
#mount -t cd9660 /dev/cd0a /mnt

but no response. 
I noticed that the led of the device doesn't flash after the command (but it should).

After mount command sometimes it says :
cd0(pciide0:1:0): readonly device
mount_cd9660: /dev/cd0a on /mnt: Device not configured

and other :

cd0(pciide0:1:0): readonly device
mount_cd9660: /dev/cd0a on /mnt: Read-only file system

The second I think is the expected response but if you type 'df' there is no entry about /mnt or /dev/cd0a. 
And  'ls /mnt' shows an empty directory.

Finally, I'd to say that the cdrom device is not accessable even through the installation. I have downloaded ftp://iso.de.netbsd.org/pub/NetBSD/iso/1.5.2/i386cd.iso
it boots but I couldn't install the sets from the local cdrom. So I did the install via ftp on my lan at home.

The same device works perfectly under dos, windows, linux, and FreeBSD.

Well I hope that its not something BIG (even better me) and you will help me on this.

Thanks for your time :)
