Thats not an excuse.

To write a device driver in the late 90'th that does not work with
_ALL_ modern ATAPI cdroms is just a failure of the programmers and
terrible ignorance from Sun. I've never seen such problems with
anything operating system except Solaris.

And the Sun guys don't do anything against it. Even with modern
supported IDE controllers you are limited to 120 GB with Solaris 10.
This sucks, sucks, sucks.
