DECstations require 512 byte sector size of CDROM drive to work properly.

RRD42/RRD44 CD-ROM (Toshiba OEM?) have jumper selectors between 512 byte
(pretending harddisk) and 2048 byte (standard).

RWZ21 "Magoneto Optiocal Disk" drive also has 512 byte sector size.  (I
have no experience of it with NetBSD/pmax, though)
