I don't think so, Chuck. I can boot with a dos floppy and it's fine. I can also boot using a Linux Lilo boot disk and everything is fine. Only the installation boot disk with speakup.i on it has done this. I am tempted to go up to the ftp site and snag the one on line and see if there's anything different. Perhaps the one from the CD I burned is a bit funky or something.
