Abstract

Problem Solved By This Invention: Boot viruses can put the wrong information in the master boot record so that your operating system can not be located. Once the boot record is destroyed and you do not have a backup copy, it is impossible to recover the system unless you reformat the hard drive. Unfortunately this destroys all of your data. The other fix is to have a backup copy of your boot record on a floppy diskette. Of course most people do not back up their boot record. This invention will copy the boot record of the hard drive to the system EEPROM. Therefore if the boot record is destroyed then the system can recreate the boot record from the EEPROM.

Backup Master Boot Record for Virus Recovery

   Problem Solved By This Invention:

   Boot viruses can put the wrong information in the master
boot record so that your operating system can not be located. Once
the boot record is destroyed and you do not have a backup copy, it is
impossible to recover the system unless you reformat the hard drive.
Unfortunately this destroys all of your data.  The other fix is to
have a backup copy of your boot record on a floppy diskette.  Of
course most people do not back up their boot record.  This invention
will copy the boot record of the hard drive to the system EEPROM.
Therefore if the boot record is destroyed then the system can
recreate the boot record from the EEPROM.

   Description of Invention:

   The Master Boot Record (MBR) is the information in the
first sector of the bootable hard drive that identifies how and
where an operating system is located so that it can be booted
(loaded) into the computers' main storage or RAM.  The Master Boot
Record is also sometimes called the "partition sector" or the "master
partition table" because it includes a table that locates each
partition that the hard disk has been formatted into.  In addition to
this table, the MBR also includes a program that reads the boot
sector record of the partition containing the operating system to be
booted into RAM.  In turn, that record contains a program that loads
the rest of the operating system into RAM.  This information is
critical because...
