John Baldwin bce816b9cc - Don't blindly assume that there are 8 hard drives installed. Instead,
use the BIOS Equipment List to determine how many hard drives are
  installed and if the drive number we received in %dl is valid.
- Don't bother to disable interrupts when setting up the stack.  The 8086
  and beyond implicitly disable interrupts after an instruction that sets
  %ss (for example, a pop or a mov) so that you can safely set %ss and %sp
  in two consecutive instructions.  An exception to this is the lss
  instruction, which can set both registers simultaneously and thus doesn't
  need this hack.
- Add support for EDD BIOS extensions to support booting off of hard drives
  of nearly arbitrary length.
