Abstract

Disclosed is a method by which a Personal Computer that is shared by more than one user can be set to power-up into a specific user's configuration.

Multi-User System Environment

      Disclosed is a method by which a Personal Computer that is
shared by more than one user can be set to power-up into a specific
user's configuration.

      This invention is for use in all personal computers,
workstations, and portable computers.  Today, personal computers are
inherently "personal".  This implies that all the security features
built into a specific computer are usable by essentially a single
user.  Other users may be given access to the computer (and through
its security barriers) by obtaining appropriate passwords and
information, by explicit sharing.

      When a computer is powered on, it runs through Power On Self
Test (POST) and checks for any entered power-on password, if this was
setup.  If this computer were being used at home with more than one
user having access to the computer, then each person in the home
would need to be told the password.

      Once past the password, the system boots up through the
operating system and quiesces at the desktop that has been setup.
This desktop may not be every person's favored location, and there
may be a  sequence of keystrokes that follow to bring the current
user into his favored environment.  When this is done multiple times
a day, it can be  quite frustrating.

Quick Summary

      There is a very simple way around this problem.  If the
personal computer had a switch at the front panel which allowed a
user to set a "dial" before powering up, the system can then boot
with all the parameters associated with that particular dial setting.
This is the base and simplest embodiment of this invention.

      The switch may be a rotary switch or a push button switch, and
it may have a fixed set of numbers or may be associated with a Liquid
Crystal Display (LCD) display with the capability of displaying a
larger set of numbers.

An implementation of multiple user setup:
  1.  Enter hardware setup
      o  Find the entry for number of users
      o  Type in the number of users (e.g., 5)
  2.  Go to LCD panel and push the button, the LCD panel will
       circulate through the max number (e.g., 1...5) setup in
       the previous step.  Stop at the number representing you.
  3.  Power-up the sys...
