Abstract
A data storage system includes a disc drive accessing system for accessing an entire storage capacity of a disk. The disk drive to be accessed is identified and address parameters for the disk are read from the disk by a host computer under instructions from a program in a Basic Input/Output System (BIOS) extension memory located on an adapter connected between the host computer and the disk drive. The address parameters read from the disk are used by the host computer to access each and every address location on the disk drive. The BIOS extension memory is activated by the BIOS memory upon power-up of the host computer.
Claims8
A data storage system, comprising:
- a disk drive having address locations for storing data, the disk drive having address parameters, the address parameters including information pertaining to a capacity of the disk drive;
- a host computer which accesses the address locations on the disk drive to retrieve data from the disk drive and to write data to the disk drive, the host computer including a basic input/output system (BIOS) memory containing predetermined address parameters corresponding to a plurality of types of disk drives;
- and
- an adapter connecting the host computer to the disk drive, the adapter including:
- a basic input/output system (BIOS) extension memory storing a program, the host computer being responsive to the program to interrogate the disk drive to determine the type of the disk drive and to read address parameters from the disk drive, the host computer being responsive to the address parameters from the disk drive to allow the host computer to access each and every address location on the disk drive.
In a data storage system comprising:
- a disk drive having address parameters;
- a host computer;
- and
- a basic input/output system (BIOS) having a basic input/output system (BIOS) memory;
- the improvement comprising an adapter connected between the host computer and the disk drive, the adapter including:
- a basic input/output system (BIOS) extension memory storing a program, the host computer being responsive to the program to interrogate the disk drive to determine the type of the disk drive and to read address parameters from the disk drive, the host computer being responsive to the address parameters from the disk drive to allow the host computer to access each and every address location on the disk drive.
