Abstract
Abstract BIOS updating is performed after saving an old BIOS to a spare storage area. A current version BIOS stored in a first bank of a flash ROM is moved to a second bank of the flash ROM, and a new BIOS supplied from a home server to a network interface card is stored in the first bank to complete BIOS updating. If the new BIOS does not run well, the old BIOS in the second bank of the flash ROM is moved to the first bank through a RAM to be reinstalled.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
88 words
A program updating method of updating a current basic program stored in a main area of storage means by replacing the current basic program with a new basic program on the basis of an updating program stored in a common area of the storage means, said method comprising the steps of: copying to the spare area of the storage means the current basic program read out from the main area; and finally writing the new basic program to the main area on the basis of the updating program.
Claim 2
Dependent Claim
88 words
A program updating method of updating a current basic program stored in a main area of storage means by replacing the current basic program with a new basic program on the basis of an updating program stored in a common area of the storage means, said method comprising the steps of: copying to the spare area of the storage means the current basic program read out from the main area; and finally writing the new basic program to the main area on the basis of the updating program.
Claim 3
Dependent Claim
102 words
An information processor comprising: storage means having a main area in which a current basic program is stored, a common area in which an updating program describing a procedure for updating the basic program is stored, and a spare area in which the basic program is stored before it is updated; and processing means for performing updating on the basis of the updating program stored in the common area of said storage means, said updating including copying to said spare area the current basic program read out from said main area and finally writing a new basic program to said main area.
Claim 4
Dependent Claim
102 words
An information processor comprising: storage means having a main area in which a current basic program is stored, a common area in which an updating program describing a procedure for updating the basic program is stored, and a spare area in which the basic program is stored before it is updated; and processing means for performing updating on the basis of the updating program stored in the common area of said storage means, said updating including copying to said spare area the current basic program read out from said main area and finally writing a new basic program to said main area.
Claim 5
Dependent Claim
