The environment descriptor block (yeah, AmyDS does have one, kinda) is a
description of the computer's hardware and software configuration. It
lets a program know what type of processor it's running on, how much RAM
is available, what the operating system version is, what devices are
available, what device drivers are installed, what the system clock
speed is, that sort of thing. It's most useful for operating systems 
that are specifically designed to run on a wide variety of different
types of computers with different procesors and hardware configurations,
like, say, Z-System or MS-DOS...
