I have three computers.
One that just says boot from atapi cd rom (i've checked the boot setup etc. it's a fresh hard drive which I need to install windows on (it used to do this with an old hard drive the one I put in the second computer to test, so I bought a new hard drive but it's still doing this any ideas))
And the other just has a flickering - in the top left it used to work before I put in an old hard drive.
Also the last one says boot from atapi cd rom and then says failure straight away!
