Unable to write to CD-R

I am having trouble burning an iso image to a CD-R using FreeBSD 4.10.
I have tried using
burncd , cdrecord, and growifofs, all appear to have basically the same
problem (see details below)
"Operation not permitted". The only thing bugs me is dmesg reports my
drive as a DVD-R.
I am not sure if this is the problem or how to addressing correcting it
if it is. Note: the BIOS
report the drive to be TOSHIBA DVD-ROM SD-R6112 1031.
Can anyone give me some direction as to what I should try next, or
better, I can the burner working?
Details:
FYI: I read the CD-Writing Howto and several other articles and followed
the instructions therein to the best of my ability (you be the judge). This
included:
- logging in as root;
- adding "device atapicam" to the kernel configuration and rebuilding
the kernel;
- creating /etc/devfs.conf as follows:
link acd0 cdrom
link acd0 dvd
perm acd0 0660
perm cd0 0660
perm pass0 0660
perm pass1 0660
perm pass2 0660
perm pass3 0660
perm xpt0 0666
- installing cdrecord, dvd+rw-tools
- ensure that the drive can read CD's and DVDs
- running ./MAKEDEV pass10 in the /dev directory
also added these
hw.ata.ata_dma="1"
hw.ata.atapi_dma="1"
to /boot/loader.conf
mount -t cd9660 /dev/cd0 /cdrom # works fine CD's and DVD's
Here's some things I tried:
burncd -f /dev/acd0c -s 12 data 5.2.1-RELEASE-i386-disc1.iso fixate
burncd: open(/dev/acd0c): Operation not permitted
cdrecord -scanbus
Cdrecord 2.00.3 (I386 .....
