Thanks franz
I tried more than you suggested. There i no response.

There is a fix for the problem.

While meddling with it I got a message; it is to follow the instructions from the following to solve the problem:
[Repository Integrity Check Failed] --> The title of the error message

Sun Message ID: SMF-8000-MY

It fixed a problem in a database. However, I can't get the graphical environment.

Then I removed entire program and tried with the Solaris Express version.

I faced the same funny problem. [ ata_disk_start: Select failed ]

The Solaris Express version is an offshoot of Solaris. So the same problem should be there.

For me the error message borders some hardware problems. I searched the message on Google.

I don't know what to do.
I would follow your suggestion.
