Ok, we've been here way in the past. You can use all the current "IDE"
DVD drives (everything, including dual layer drives) with the Ultra2 if
you purchase a SCSI/IDE Bridge. The bridge is made by Acard. The link
to the Bridge is:
I've been using the latest Sony DVD drives in my Ultra2 with that bridge.
Why would you need a driver?
What drivers? It just worked. The bridge is SCSI, so Solaris sees it
no problem. The DVD player is IDE or ATAPI, so the bridge sees it.
