   Well...some references to EFI for those who are not familiar with this (that    
   includes me..lol) => http://wiki.osx86project.org/wiki/index.php/EFI   
      
   ...also what appears (various claims) to be a replacement interface, the UEFI

   http://en.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface   
      
   Jonathan you may have been referencing UEFI when saying EFI...maybe?   
      
   But boy...that seems like a bit complex proposition no? If I understood    
   correctly, the BIOS itself has to be able to support EFI...maybe a bit more of   
   a   
   question then statement actually...   
      
   The Linux mptable code seems fairly straightforward...I'm guessing I will have    
   easier time understanding the OS2 specific API calls to use as opposed to    
   getting a EFI solution in place.
