Hmm.

Mine says:

pciide1 at pci0 dev 11 function 0: CMD Technology PCI0646
pciide1: bus-master DMA support present
pciide1: primary channel wired to compatibility mode
pciide1: secondary channel wired to compatibility mode
atapibus0 at pciide1 channel 1
cd0 at atapibus0 drive 0: <CD-532E-B, , 1.0A> type 5 cdrom removable
cd0: 32-bits data port
cd0: drive supports PIO mode 4, DMA mode 2
cd0(pciide1:1:0): using PIO mode 4, DMA mode 2 (using DMA data transfers)

It's a TEAC 32x.  Works fine.

Weird.  I assume the drive is jumpered as a master, yes?  Any possibility
that it's one of the weird drives which distinguishes between "master" and
"only device"?
