Abstract
A system and method for access control of a hardfile responsive to a computer system having an operating system is disclosed. The method includes detecting a special boot condition during a pre-boot test of the computer system; and altering, in response to the special boot condition, an operating system access configuration of the hardfile. The system includes a computer system that adjusts an operating system access to a hardfile based upon various boot conditions.
Claims25
A method for access control of a hardfile, responsive to a hardfile controller included in a computer system having an operating system performing a pre-boot test, comprising the steps of:
- a) detecting a boot condition during the pre-boot test;
- and
- b) altering, in response to the boot condition, an operating system access configuration of the hardfile.
A method for access control of a hardfile, responsive to a computer system having an operating system, comprising the steps of:
- a) detecting a special boot condition during a pre-boot test of the computer system;
- and
- b) altering, in response to the special boot condition, an operating system access configuration of the hardfile.
A storage system for a computer system having an operating system and a preboot procedure, comprising:
- a hardfile for non-volatile storage of the operating system on a first part of the hardfile and a plurality of user data on a second part of the hardfile;
- and
- a hardfile controller, coupled to the hardfile and responsive to a special boot condition detected by the pre-boot procedure, for dynamically reconfiguring operating system access to the hardfile to permit access to both the first part and the second part in a first mode and to permit access to only the first part in a second mode.
A storage system for a computer system having an operating system, comprising:
- a hardfile for non-volatile storage of the operating system on a first part of the hardfile and a plurality of user data on a second part of the hardfile;
- and
- a hardfile controller, coupled to the hardfile and responsive to a special boot condition detected by a pre-boot procedure of the computer system, for dynamically reconfiguring operating system access to the hardfile to permit access to both the first part and the second part in a first mode and to permit access to only the first part in a second mode.
A storage system controller for a hardfile of a computer system having an operating system and a pre-boot procedure, the hardfile for non-volatile storage of the operating system on a first part of the hardfile and a plurality of user data on a second part of the hardfile, comprising:
- a hardfile controller, coupled to the hardfile and responsive to a boot condition detected by the pre-boot procedure, for dynamically reconfiguring operating system access to the hardfile to permit access to both the first part and the second part in a first mode and to permit access by the operating system to only the first part in a second mode.
A storage system controller for a hardfile of a computer system having an operating system, the hardfile for non-volatile storage of the operating system on a first part of the hardfile and a plurality of user data on a second part of the hardfile, comprising:
- a hardfile controller, coupled to the hardfile and responsive to a boot condition detected by a pre-boot procedure of the computer system, for dynamically reconfiguring operating system access to the hardfile to permit access to both the first part and the second part in a first mode and to permit access by the operating system to only the first part in a second mode.
A hardfile system for a computer system, comprising:
- a hardfile for nonvolatile storage of a operating system and user data;
- means, coupled to the computer system, for detecting a special boot condition during the pre-boot test;
- and
- means, coupled to the hardfile and to the detecting means, for altering, in response to the special boot condition, an operating system access configuration of the hardfile.
A hardfile storage system, comprising:
- a hardfile for nonvolatile storage of an operating system for a computer system in a first part and for nonvolatile storage of user data in a second part;
- and
- means, coupled to the hardfile, for dynamically enabling operating system access to the hardfile in a first mode and a second mode, wherein the first mode enables access to the first part and the second part and the second mode enables access to only the first part.
A computer usable medium having computer readable program code means embodied therein for access control of a hardfile, responsive to a hardfile controller included in a computer system having an operating system performing a pre-boot test, the computer readable program code means in the computer usable medium comprising:
- computer readable program code means for causing the computer system to detect a boot condition during the pre-boot test;
- and
- computer readable program code means for causing the computer system to alter, in response to the boot condition, an operating system access configuration parameter of the hardfile.
A computer readable medium containing program instructions for access control of a hard file in a computer system, the program instructions for:
- a) detecting a boot condition during the pre-boot test;
- and
- b) altering, in response to the boot condition, an operating system access configuration of an access parameter of the hardfile.
