The driver for the NVidia SATA controller MCP55 and CK804 chipsets included in the Solaris 10 5/09 release does not support ATAPI CD/DVD devices.
During system installation or upgrade by using a SATA CD/DVD device, the Solaris installer starts and appears to function but fails with the following error messages:
ERROR: The disc you inserted is not a Solaris OS CD/DVD
There were problems loading the media from /cdrom
During normal system operation, the SATA CD/DVD drive is not configured and cannot be used.
Workaround: Use the USB CD/DVD.
