Bochs/bochs/main.cc
Christophe Bothamy b84c82e80c - changed the floppy_bootsig_check syntax to be more logical. the syntax is now : 
floppy_bootsig_check: disabled=[0|1]. It is not disabled by default.
  Sorry for any inconvenience it could cause
- changed the default (if cmos reg is 0) behavior for the floppy boot signature
  check, so the new bios is compatible with older bochs binaries (useful if we
  want to use the new bios when we release 1.4.1) :
  1 : disabled
  0 : enabled
- added info at launch time about the boot device and the floppy boot signature
  check
- added a "LBA capable" flag in the ata controller
