I think this should probably go into the FAQ or Handbook, and perhaps

Yes, it does. Dip switch 4 ("Device mode") has a factory setting of
Closed ("Optical"). You need to set it to Open ("HDD").
That done, when you boot with -v, you will see something like:
ahc0: target 6 synchronous at 5.0MB/s, offset = 0xf
(ahc0:6:0): "FUJITSU M2512A 1314" type 0 removable SCSI 2
sd3(ahc0:6:0): Direct-Access
sd3(ahc0:6:0): ILLEGAL REQUEST asc:24,0 Invalid field in CDB sks:c0,4
sd3 could not mode sense (4). Using ficticious geometry
217MB (446325 512 byte sectors)
sd3(ahc0:6:0): with 217 cyls, 64 heads, and an average 32 sectors/track
You can safely ignore the error message, and FreeBSD will treat it as a
removable hard drive.
On a side note, I've noticed that sysinstall scans all hard drives when
it runs, whether or not they are mounted. Because of this, you will not
be able to eject the MO while sysinstall is running, even if it is not
mounted.
