Thanks Hata_ph for your advice, and when I went through with the install there appeared a keyboard selection set which enabled me to select Dvorak; however, during install, when it came time to switch cds to the second one included in my SOHO 7.0 Deluxe Edition, the program wouldn't accept it, and kept instructing me to insert the correct cd as the one I did insert [which came with the other one -- purchased and not downloaded -- that was accepted and is in pristine condition with no dust, etc.] was NOT THE CORRECT cd. Kept trying but never worked.
Any suggestions appreciated [any idea what is on that cd? possibly I can get by without it, but would like to check it out].
Is KDE on that second cd, as can only get one of the 5 or 6 desktop selections to come up [xfce with thunar]?
