Abstract: The present invention provides a method and system for supporting discontiguous drive arrangements in a computer system using IDE control parameters. In a standard computer system having a central processing unit, user interface, short term volatile memory storage, and at least one to four or more long term static memory storage devices (eg hard disks), all or which are connected by a bus to the CPU, the invention is used to provide access to the long term memory storage devices in a manner transparent to both the system and the user. According to the invention, the system first defines a primary address for a first set of long term storage locations as well as a secondary address for a second set of long term storage locations contiguous to the first set of long term storage locations. Next, the system defines first and second logical drive numbers within the primary address and within the secondary address. Next, the system determines whether at least one long term static memory devices are present, which devices have a physical drive number. Next, the system translates the logical number from either the primary address or the secondary address to the physical drive number corresponding to the present long term static memory devices previously identified.

Abstract: A personal computer system according to the present invention comprises a system processor, a random access memory, a read only memory, and at least one direct access storage device. A direct access storage device controller coupled between the system processor and direct access storage device includes a protection mechanism for protecting a region of the storage device. The protected region of the storage device includes a master boot record, a BIOS image and a system reference diskette image. The BIOS image includes a section known as Power on Self Test (POST). POST is used to test and initialize a system. Upon detecting any configuration error, system utilities from the system reference diskette image, such as set configuration programs, diagnostic programs and utility programs can be automatically activated from the direct access storage device.
