Abstract: An apparatus and a method in a data processing system are provided for insuring the security of data accessed from removable media. Normal virus scanning occurs after data is loaded into the main memory, but infection by a virus may have already occurred by this time. Therefore, it would be beneficial to check for possible virus infection before the data is transferred to main memory. A security key is read from the removable media. As encrypted data is read from the device, it is decrypted using the security key and then re-encrypted using the same security key to produce new data. The original data is accepted and sent to main memory if it is identical to the new data produced by decryption and re-encryption. If the two sets of data are not identical, then the data transmission from the device is aborted and all data on the removable media is rejected. The decryption/re-encryption checking is performed in hardware and so it can occur in real time.

Abstract: A method and system for protecting electronic files from unauthorized access. The drive on which the file is stored is provided with a hardware identification code, which is unique to the drive. An Operating System (OS) extension allows a user to provide a security code required to access a requested drive. OS device driver, working in conjunction with the extension of the OS checks the requested drive to determine if an access code is required, and the drive responds with the security code or a default code. The default code indicates that the drive is globally accessible to users on the system. When a security code is returned, the OS compares the security code to the access code provided and provides the user with access to the drive only when the access code matches the security code.

Abstract: A method and an apparatus is presented for configuring a system bus topology dynamically. In a preferred embodiment, the system bus is a Small Computer System Interface (SCSI) bus that connects a “daisy” chain of disk drives. Two types of disk drives are used: single ended (SE) “Ultra” drives capable of 20 MHz operation and LVD (low voltage differential) “Ultra Plus” drives capable of 40 MHz operation. LVD disk drives can also function in the slower SE mode. The first drive in the chain of drives may need to be connected by a cable over three feet long. This introduces signal degradation that is often overcome by introducing redrive circuitry to boost signal quality. This is an expensive solution and a much easier solution is presented: install a jumper between the last drive in the chain and the first drive. However, if LVD bus mode is used, then this jumper solution does not work and the jumper must be removed.

Abstract: A data processing system and method included within an oscilloscope for independently analyzing a signal input into the oscilloscope. The oscilloscope includes a plurality of triggering modes. A plurality of trigger parameters are specified for each of the triggering modes. Thereafter, the oscilloscope automatically analyzes the input signal, independently from any user input, utilizing each of the triggering modes and the trigger parameters specified for each of the triggering modes. The input signal includes a desired waveform and a plurality of undesired waveforms. While the oscilloscope is automatically analyzing the input signal, a determination is made regarding whether the oscilloscope triggered on one of the undesired waveforms. When it is determined that the oscilloscope triggered on one of the undesired waveforms, the undesired waveform upon which the oscilloscope triggered is stored.
