I have gotten through the first few steps of installing version 3.0 on a Toshiba 1405 laptop, including creating a password and logging on.
The problem is that only a small part of my monitor screen is being used for the (character-based) display, and the lowest visible line is not the last line of standard output. For example if the file qq is 25 lines long, and I type cat qq, I only see the first 21 lines. Pressing return shows me the remaining lines, one at a time. I don't know whether this has anything to do with the problem, but my first try used the CheapBytes CDROM set, and I used the one labelled "Install #1, non-US" instead of "Install #1".
