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)? -Dave -- David Frascone Oxymoron: Reinvent.
