The second time you have to answer the same question is the right time to consider
writing the answer down somewhere
When I was trying to install Solaris Nevada (http://www.opensolaris.org/)
into my Toshiba Tecra M3 laptop for the first time (about 10 months ago), I experienced strange error messages and was not able to proceed. Until I changed my CMOS settings.
Then one of my colleagues experienced the same issue and recently one another asked me for a hint. So I decided to publish the following two screenshots. Hope it might help you as well.
