Could you please post th dmesg.txt file created with (in a terminal) dmeag > dmesg.txt ?
And your onboot.lst file? (whatever you try to boot: Xvesa or Xorg).
floppy, thanks for your interest, but right now I'm using a different machine. I will soon try again to get TC with Xorg going on the computer originally described, in which case I will post the output of dmesg and the content of onboot.lst. Thanks so much!
