I downloaded infrarecorder, and I did have a minor success. I now have
a CD that shows several different files. But it still will not boot
completely. I am beginning to think my old Toshiba is the culprit,
though the system DOES open and let me choose from that first opening
menu. However, after a while the screen goes dark and I hear the CD
drive grinding -- drive lights for CD and HD go on and off. I am used
to seeing a list of what's happening as the boot progresses, so I
assume that NOTHING is happening.

One of the opening menu choices is to check the integrity of the CD,
and that check showed everything OK. I don't know where that puts me,
however.

Here's something different. When I boot into v5.04, the CD-ROM shows
up on the desk top. If I click on it, the various files (from v7.04)
are there. I don't suppose it is as simple as picking one of those
files to install v7.04 while in v5.04???

I guess I will burn one more copy of the disk, and see if a real slow
burn might not clean things up. I am ready to try most anything, now.
I may even go so far as to buy a bootable CD (horrors).
