   BIOS vs UEFI

   From: muta...@gmail.com   
      
   It seems to me that the BIOS concept of reading the   
   first sector of the disk into memory and immediately   
   executing it, from offset 0, is a lot cleaner than the   
   UEFI concept of requiring a FAT-formatted disk with   
   subdirectories.   
      
   If you're going to go for the latter option of a FAT-formatted   
   disk, shouldn't it be something internal to the computer, on   
   a flash drive, that results in loading the first sector from the hard   
   disk and executing it, but perhaps in PM32 or LM64 instead   
   of RM16?   
      
   Passing the UEFI data structure to the code on the first   
   sector would seem to be more appropriate than doing   
   interrupts though.
