True! :)  Does this mean it is operating properly a) without
special prodding b) only with prodding c) never?
I'm just curious if any of this would bring down the bus speed when
accessing the cdrom if I had any UW hd's on the bus for example, or if it
is purely a cosmetic issue.  Also wondering why ncr0 works fine with it :P


sapphire:~ % camcontrol inquiry cd1 -D -R=20
pass1: <PLEXTOR CD-ROM PX-40TW 1.01> Removable CD-ROM SCSI-2 device=20
pass1: 40.000MB/s transfers (20.000MHz, offset 15, 16bit)
sapphire:~ % camcontrol inquiry cd1=20
pass1: <PLEXTOR CD-ROM PX-40TW 1.01> Removable CD-ROM SCSI-2 device=20
pass1: 6.600MB/s transfers  (16bit)
