System and method for loading programs from HDD independent of operating system
View Patent ↗A method for booting into computer memory a non-operating system (O.S.) program from a hard disk drive (HDD) prior to booting into memory an O.S. from the HDD. The method includes establishing a table of contents (TOC) on the HDD that contains entries for special O.S. programs. A pointer to the TOC is placed in non-volatile memory of the computer that is associated with the HDD, and when BIOS of the computer is prompted to load into memory one of the special O.S. programs, the pointer is accessed and used to locate the TOC, which in turn is accessed to load the special O.S. program.
1. A hard disk drive (HDD), comprising:
at least one program; and
a table of contents (TOC) data structure comprising:
at least one image entry corresponding to the program, the image entry including an image identifier, a beginning LBA of the image, a size of the image, and a memory load location for the image, the memory load location indicating where to load the image into memory during boot; and
a TOC table entry including at least an identifier unique to the TOC and TOC validation information.
2. The HDD of claim 1 , wherein the HDD includes a master boot record (MBR) storing a pointer to the TOC.
3. The HDD of claim 1 , wherein the image entry includes validation metrics useful for validating the program.
4. The HDD of claim 1 , wherein the image entry includes a program execution starting point.
5. The HDD of claim 1 , wherein the program is not a standard operating system (O.S.) and is bootable from disk without the aid of a standard O.S.
