On a Toshiba Tecra laptop, 1.6 (i386) reports:

atapibus0 at wdc1 channel 0: 2 targets
cd0 at atapibus0 drive 0:  type
5 cdrom removable
cd0: drive supports PIO mode 3, DMA mode 1

Mounting it does:

mount -t cd9660 /dev/cd0a /mnt
mount_cd9660: /dev/cd0a on /mnt: Operation not supported by device

BSD/OS 4.2 sees it as:

wdc1 at isa0 iobase 0x170 irq 15: disk controller
wdpi0 at wdc1 drive 0: TOSHIBA CD-ROM XM-1502B rev=2996 4600585041
wdpi0: transfer size=2048 polled cmd DRQ
wdpi0: Delaying to allow ATAPI device to finish self-test
wdpi0: Unit did not become ready
wdpi0: cdr_rd meth2 audio_play m2f1 m2f2 multi_sess cdda rwsup c2ptrs isrc
upc lock eject sep_vol sep_mute lsbf tray ms=1764K buf=128K Nvol=255
tg0 at wdpi0 target 0
sr0 at tg0 unit 0: CD-ROM: type 0x5, qual 0x80, ver 0 removable

And mounting under BSD/OS:

mount -t cd9660 /dev/sr0a /mnt
sr0: sn 0: not ready: no medium
cd9660: /dev/sr0a on /mnt: Input/Output error

Hmmm... probably just an old drive doesn't support this newly made CDRW.

Using bootlap[12].fs floppy images, I received: "[ no symbol table formats found ]". Then a uvm_fault and dumped to db> kernel debugger.
