Thx a lot for your reply. My host is running Ubuntu 20.04.1 LTS.
I installed Xorg-7.7. Xvesa.tcz wasn't listed in the onboot.lst. Now my system stops at "Booting the kernel." with a blinking cursor. boots into a black screen.
On some machines, graphics-KERNEL may be required for X to display.
tce-load -wi graphics-KERNEL
Have you installed any window manager ? (flwm, jwm, icewm, fluxbox, hackedbox, openbox ..
Please show us the contents of your tce(tce32)/onboot.lst
You might need to refresh the extensions.
