That's quite worrying as a fair number of my friends use 32 bit CPUs.
However, to be more accurate, they tend to be some kind of Pentium or Atom.
Will the 586 CPUs still be supported in future releases of  Lubuntu Linux?

OK, done that.

Also, try as I might, I couldn't get a boot menu listing the different
kernels on boot up. Tried pressing left shift or right shift, to no avail.

HTH :)

Is there anything else I can do for you?

BW,


Ian
