[Bug 272087] Re: 64 bit Ubuntu cd on 32 bit system: more helpful error message

[Bryan Quigley]

As an alternative, we could consider changing the wording in the kernel..:
arch/x86/boot/cpu.c:		printf("This kernel requires an %s CPU, ",
arch/x86/boot/main.c:		puts("Unable to boot - please use a kernel appropriate "
arch/x86/boot/cpu.c:   cpu_name function, which only has x86_64 and i686 defined

SO:
 printf("This kernel requires an %s CPU, ", cpu_name(req_level));
 printf("but only detected an %s CPU.\n", cpu_name(cpu_level));

BECOMES:
 printf("This media requires an %s bit CPU, ", req_level);
 printf("but only detected an 32 bit CPU");

SO:
puts("Unable to boot - please use a kernel appropriate "
"for your CPU.\n");

BECOMES:
puts("Please acquire the 32 bit version of the media you are trying to use\n");

Thoughts on this strategy?

Title:
  64 bit Ubuntu cd on 32 bit system: more helpful error message

Status in “gfxboot” package in Ubuntu:
  Triaged

Bug description:
  When you boot the 64 bit ubuntu desktop cd on a 32 bit system, you get
  the following error message after you try to boot:

  This kernel requires an x86-64 CPU, but only detected an i686 CPU.
  Unable to boot - please use a kernel appropriate for your CPU.

  Most people won't be able to make sense of this at all if they
  accidentally downloaded the wrong cd. There should be an
  understandable message telling you to download the 32 bit version of
  ubuntu.
