I'm sure this has an easy answer, but it's been eluding me:
I need grub, when booting, to grab some values from a particular memory
address (in flash). My code runs fine, on the platform . .
BUT -- I use the same code to *install* grub from linux, where it can
not access the physical memory address. So -- is there any way to have
stage2 only access the location when not running under an OS (i.e. when
booting)?

The answer is: use the #define GRUB_UTIL.
