 "FreeBSD only calls the BIOS SMAP call from virtual 86 mode both
  in the loader and in the i386 kernel. The fix is quite complicated and
  involves rewriting the boot code to invoke BIOS calls from real mode
  rather than virtual 86 mode."
 
 ?? but FreeBSD i386 boots and runs fine on an HP dc7700 that gives the "No 
 BIOS SMAP" error when booting AMD64. I'm completely ignorant of the boot 
 process for AMD64, but could code be lifted from i386 and moved to AMD64 to 
 solve this?
