" Suns starting with some PROM version support switching the CD-ROM 
" blocksize to 512 programmatically

ultrasparcs and obp 3

" and these newer ones can use mostly any SCSI CD-ROM device.

many/most of the oldest drives lack the blocksize mode select command
it started to change in the mid '90s

i've wondered if the command could be added to obp 2 nvramrc
