Abstract

Personal Computers (PCs) used in the home are frequently used by all the family. Often a utility, such as BootManager, is employed to partition the hard disk such that different operating systems can be selected at boot time. An example of such a configuration is DOS/Windows for the children to play games on in one partition and something else such as OS/2* Warp for the parents in another partition.

Password Protection of Separate Hard Disk Partitions

      Personal Computers (PCs) used in the home are frequently used
by all the family.  Often a utility, such as BootManager, is employed
to partition the hard disk such that different operating systems can
be selected at boot time.  An example of such a configuration is
DOS/Windows for the children to play games on in one partition and
something else such as OS/2* Warp for the parents in another
partition.

      The PC may be password protected, as may individual programs or
parts of the operating system in use.  However, there is no general
protection available for the particular disk partition in use.

      Problems can arise when the children access the parents
partition and modify or corrupt programs or data.  Presently, (since
the children must know the power-on password of the system to get to
their games partition) there is no way of protecting individual
partitions.

      The solution proposed to the example problem above is to add a
feature to the likes of BootManager such that when the desired
bootable partition is selected, the user is prompted to enter a
password for that partition before booting commences.

      By doing this, individual partitions may be protected from
unauthorized access.  Note that the same operating system may be
loaded on two (or more) separate partitions but each has a distinct
password.
