Hi Ady,

With a clone of the git repo on kernel.org I run
make spotless bios; make bios
./bios/extlinux/extlinux -i {target mounted partition}

The extlinux partition contains both kernels, ldlinux.sys, ldlinux.c32 and 
extlinux.conf, which is
PROMPT 1
LABEL 1
  LINUX {relocatable vmlinuz}
  APPEND root={target partition}
LABEL 2
  LINUX {nonrelocatable vmlinuz}
  APPEND root={target partition}

I've heard that the SeaBIOS on these machines may report an incorrect 
amount of memory, requiring (at least older versions of) syslinux to 
use/pass "mem=1500m" or some such on the APPEND line for some linux iso 
installers. As shown above, this does not affect the regression test, but 
that's not to say any incorrect report from the SeaBIOS is not involved. 
Also, I don't know if other hardware is affected.

Thanks,
Scot
