In full, something like:

  chain memtest.0 && goto memtest_ok || goto memtest_${errno}

  :memtest_ok
  echo Memory test passed
  exit

  :memtest_0x1
  echo Memory test failed
  exit

  :memtest_0x2
  echo Memory test did not complete
  exit

Note in particular that ${errno} is set only when an error occurs.

Check out the "pxe" branch from my memtest repository:

  http://git.ipxe.org/people/mcb30/memtest.git/shortlog/refs/heads/pxe

Type "make" and you should get memtest.0 built alongside the usual targets.
