Abstract

A method and apparatus for creating a new partition in a hard disk drive of a computer system and installing software (e.g., system software) into the new partition. The method of the disclosed invention reads a diskette for a unique diskette signature which, if present, indicates that the diskette contains software to be installed in a new partition. If the unique diskette signature is found to be present on a diskette, then a new partition is created on the computer system'"'"'s hard disk drive. The new partition can be of any size, and the size can, for example, be either fixed based upon predetermined settings or user-selected. After the new partition is created, it is assigned to logical drive 80h, the DOS boot drive. Once assigned to logical drive 80h, the invention boots to the diskette and the partition installation software contained on the diskette is executed. The installation software contained on the diskette then installs the software into the new partition.

Claims

1. A machine-executed method for creating a new partition in a hard disk drive of a computer system, said method comprising:

(a) reading a diskette during POST contained in a diskette drive of said computer system for detecting the presence of a unique diskette signature on said diskette; and

(b) if said unique diskette signature is found to be present on said diskette,

(i) creating said new partition on said hard disk drive during POST; and

(ii) modifying a master boot record associated with said hard disk drive during POST so that said partition can be immediately recognized by an operating system without the need for an intervening reboot.

2. The method of claim 1, wherein said new partition on said hard disk drive is of a predetermined size.

3. The method of claim 1, wherein said new partition on said hard disk drive is of a size selected by a user of said computer system.

4. The method of claim 1, said creating said partition step comprising:

(a) modifying partition table entries in a master boot record associated with said hard disk drive during POST to include information necessary to enable an operating system running on said computer system to recognize and access said new partition during a subsequent initial program load;

(b) modifying file allocation table entries associated with said hard disk drive during POST to include information necessary to enable an operating system running on said computer system to recognize and access said new partition during said subsequent initial program load; and

(c) modifying directory table entries associated with said hard disk drive during POST to include information necessary to enable an operating system running on said computer system to recognize and access said new partition during said subsequent initial program load.

5. The method of claim 1, wherein said new partition on said hard disk drive is a system partition.

6. The method of claim 1, said modifying master boot record step comprising assigning said new partition to logical drive 80h.

13. A program storage device readable by a machine and encoding a program of instructions which, when read by the machine causes the machine to perform the method of any one of claims 1, 3-7, 8-12 and 6.

7. A machine-executed method for creating a new partition in a hard disk drive of a computer system and installing partition-specific software into said new partition, said method comprising:

(a) reading a diskette during POST contained in a diskette drive of said computer system for detecting the presence of a unique diskette signature on said diskette;

(b) if said unique diskette signature is found to be present on said diskette, performing the following additional steps;

(i) creating said new partition during POST on said hard disk drive;

(ii) assigning said new partition during POST to logical drive 80h;

(iii) booting to said diskette; and

(iv) executing partition installation software contained on said diskette having said unique diskette signature, said execution of said installation software causing said partition-specific software to be installed into said new partition.

8. The method of claim 7, where in said new partition on said hard disk drive is of a predetermined size.

9. The method of claim 7, wherein said new partition on said hard disk drive is of a size selected by a user of said computer system.

10. The method of claim 7, said creating said partition step comprising:

(a) modifying partition table entries in a master boot record associated with said hard disk drive during POST to include information necessary to enable an operating system running on said computer system to recognize and access said new partition during a subsequent initial program load;

(b) modifying file allocation table entries associated with said hard disk drive during POST to include information necessary to enable an operating system running on said computer system to recognize and access said new partition during said subsequent initial program load; and

(c) modifying directory table entries associated with said hard disk drive during POST to include information necessary to enable an operating system running on said computer system to recognize and access said new partition during said subsequent initial program load.

11. The method of claim 7, wherein said new partition on said hard disk drive is a system partition.

12. The method of claim 7, wherein said partition-specific software is system utility software.
