DongSoo> it's saying that Can't Open scsi/sd@0:0.

I suspect you have another internal scsi bus, so
 
Try 
boot scsi-int/sd@0:0

DongSoo> scsi/sd@0:0   /AAPL, ROM
DongSoo> is AAPL, rom should be something else?

The second word is the default value. It is fixed
always.

If you look at the output when you type devalias,
it will tell you more information.
