1. IBM very strongly recommends upgrading your 720 to BIOS level 14. Especially, if your system has
   512MB of memory or more. By not installing this BIOS, you could experience many different types
   of problems under all of the operating systems. Some of the problems observed were: not being able
   to install OS/2, not being able to mount drives under Novell and various problems under NT.
   To avoid these potential problems, it would be in your best interest to install BIOS 14 as soon as
   possible. Even if you have less than 512MB of memory, it would be good to install this BIOS to
   avoid future problems.
