install 11.4 ioct1

Iam tring to install 11.4 on my new computer, when i start the computer the green screen pops up and syslinux starts. However when it finishes loading a dialog box pops up saying “Make sure that cd number 1 is in your drive” . Obviously it it is,
because i am booting from the dvd. I dropped to the shell where i saw this message “Inappropriate ioct1 for device”. What does all this mean.

Thank you in advance to anyone that can help

So you can’t even get to this screen and run the media check?

What OS and application did you burn the CD or DVD with?

Check the existing threads on the same problem. Maybe you find a solution.

Error “Make sure that CD number 1 is in your drive.” when installing Open SUSE 11.2, 11.3 and 11.4.
