Abstract
Abstract A computer storage medium has software executed at startup of the computer, before the computer executes an ultimate operating system. The software provides anti-virus, maintenance and/or repair functions. In one embodiment, the software is stored on a "hidden partition" of the storage medium; the hidden partition not only shields the software from many viruses, but provides storage space that does not reduce formatted or advertised capacity.

A virus-resistant storage medium for use with a computer, the storage medium being selectably actuable and writable by a user and comprising: (a) anti-virus software stored on the storage medium and configured to cause the computer to detect and remove from a component thereof at least one virus; and (b) means for causing the computer to execute the anti-virus software upon startup of the computer but before the computer executes an ultimate operating system.
Claim 3
Dependent Claim
14 words
The virus-resistant storage medium of claim 1 wherein the medium is a flash ROM.
Claim 4
Dependent Claim
14 words
The virus-resistant storage medium of claim 1 wherein the medium is a bubble RAM.
Claim 5
Dependent Claim
15 words
The virus-resistant storage medium of claim 1 wherein the medium is an optical storage device.
Claim 6
Dependent Claim
14 words
The virus-resistant storage medium of claim 1 wherein the medium is a tape drive.
Claim 7
Dependent Claim
14 words
The virus-resistant storage medium of claim 1 wherein the medium is a network disk.
Claim 8
Dependent Claim
45 words
The virus-resistant storage medium of claim 1, wherein the execution-causing means comprises bootstrap software stored on the disk, execution of the bootstrap software causing the computer to execute the anti-virus software prior to post-bootstrap operations, the bootstrap software being executed upon startup of the computer.
Claim 9
Dependent Claim
78 words
The virus-resistant storage medium of claim 1, wherein: (a) the computer comprises memory and registers; (b) the computer has an initialization state in which the memory and registers of the computer accurately reflect the amount of memory on the computer and no interrupt vector in the computer contains an address of a routine within a virus; and (c) the anti-virus software is configured to cause the computer, after detecting and removing a virus, to enter the initialization state.
Claim 10
Dependent Claim
98 words
A virus-resistant storage medium for use with a computer, the storage medium having a conventional storage capacity and comprising: (a) a hidden partition comprising storage space inaccessible to conventional programs and not reducing the conventional storage capacity; (b) means for describing the conventional storage capacity but not describing the hidden partition, thereby making the hidden partition inaccessible to conventional programs; (c) anti-virus software stored in the hidden partition and configured to cause the computer to detect and remove from a component thereof at least one virus; and (d) means for causing the computer to execute the anti-virus software.
Claim 11
Dependent Claim
98 words
A virus-resistant storage medium for use with a computer, the storage medium having a conventional storage capacity and comprising: (a) a hidden partition comprising storage space inaccessible to conventional programs and not reducing the conventional storage capacity; (b) means for describing the conventional storage capacity but not describing the hidden partition, thereby making the hidden partition inaccessible to conventional programs; (c) anti-virus software stored in the hidden partition and configured to cause the computer to detect and remove from a component thereof at least one virus; and (d) means for causing the computer to execute the anti-virus software.
Claim 12
Dependent Claim
40 words
The virus-resistant storage medium of claim 9, wherein the execution-causing means comprises bootstrap software stored on the disk, execution of the bootstrap software upon startup of the computer causing the computer to execute the anti-virus software prior to post-bootstrap operations.
Claim 13
Dependent Claim
83 words
The virus-resistant storage medium of claim 9, wherein the anti-virus software comprises at least one anti-virus program and the execution-causing means comprises: (d1) bootstrap software stored on the storage medium; and (d2) a bootstrap-time operating system stored in the hidden partition for causing the computer, upon startup, to automatically execute the bootstrap software, said bootstrap-software execution causing the computer to execute the bootstrap-time operating system, said operating-system execution causing the computer to execute the at least one anti-virus program prior to post-bootstrap operations.
Claim 14
Dependent Claim
52 words
The virus-resistant storage medium of claim 11 further comprising: (e) maintenance software stored in the hidden partition for causing the computer to detect and repair damage to information stored on a component thereof; and wherein (f) the bootstrap-time operating system causes the computer to execute the maintenance software prior to post-bootstrap operations.

A storage medium for use with a computer, the storage medium being selectably actuable by a user and comprising: (a) maintenance software for causing the computer to detect and repair damage to information stored on a component thereof; and (b) means for causing the computer to execute the software upon startup of the computer but before the computer executes an ultimate operating system.
Claim 17
Dependent Claim
94 words
A storage medium for use with a computer, the storage medium having a conventional storage capacity and comprising: (a) a hidden partition comprising storage space inaccessible to conventional programs and not reducing the conventional storage capacity; (b) means for describing the conventional storage capacity but not describing the hidden partition, thereby making the hidden partition inaccessible to conventional programs; (c) maintenance software stored in the hidden partition for causing the computer to detect and repair damage to information stored on a component thereof; and (d) means for causing the computer to execute the software.
Claim 18
Dependent Claim
