TL;DR: In this paper, the authors propose a method of permitting the execution of a disk loaded into the disk drive, the disk having a plurality of tracks, comprising the steps of writing data in non-standard format and length to a normally unaccessible track of the disk, the data including an encrypted password, the password being located at an arbitary location within the data, reading the data resulting in an error signal, locating an indexing position and applying an offset to identify the password, and unencrypting and authenticating the password in order to execute the disk.

TL;DR: In this article, a method of controlling an image processing apparatus with a controller including a first memory, a removable memory medium having a boot sector, a directory, and identifiable files with header sectors, selected files of the removable medium capable of being booted into the first memory for controlling the image processing means is presented.

TL;DR: In this article, the authors propose a system for saving and restoring critical files on the rigid disk of an electrostatographic reproduction machine in the event the disk becomes corrupted wherein the critical files have an identifying header sector transparent to the disk directory, with a floppy disk having a bootable locate and read utility to identify critical files and read them to blank floppy disks.

TL;DR: In this article, a system architecture and method for synchronizing the slave clock of one or more resources with the master clock of a controller in a document processing system is presented, which includes: a) saving a value of master clock ( 615 ); b) generating a discrete clock synchronization interrupt signal and distributing the interrupt signal to the resource(s) via the control bus ( 625 ); c) receiving the interrupt signals at each resource ( 630 ) and saving a slave clock ( 640 ); d) sending a message to the controller via a network to request the value saved for the
