Abstract: Diskette drive determination in which a read/write head in a diskette drive is instructed to move to a track that is inaccessible on one type of diskette drive. The head is then stepped back toward a track associated with a sensor indicating the positioning of the head over the track. The number of steps required to activate the sensor determines which type of drive is being used.

Abstract: Migrating virtual machines among networked servers, the servers coupled for data communications with a data communications network that includes a networking device, where migrating includes: establishing, by a virtual machine management module ('VMMM'), one or more virtual machines on a particular server; querying, by the VMMM, the networking device for link statistics of a link coupling the network device to the particular server for data communications; determining, by the VMMM in dependence upon the link statistics, whether the link coupling the network device to the particular server is degrading; and if the link coupling the network device to the particular server is degrading, migrating a virtual machine executing on the particular server to a destination server. In some embodiments, migrating occurs is carried out only if non-degrading link is available. If no non-degrading links are available, the network device, rather than the link, may be failing.

Abstract: This invention relates to the adaptation of personal computers to communication through external networks, and more particularly to the ready adaptation of such computers to networks of varying characteristics, such as telecommunications networks located in various countries of the world. The adapter has first and second controllable digital/analog convertors for exchanging signals with a digital signal processor of the computer and controllable by a bus interface controller of the computer for converting signals between digital and analog forms. The adapter also has first and second connectors of the type required by the particular external network, coupled to the convertors for exchanging signals with the external network and for exchanging signals with an external device such as a telephone set.

Abstract: A logic controlled gate is inserted in the arbitration logic of a computer system that supports multiple masters on a data bus. In such a system with arbitration for data bus ownership, the gate is so controlled that competitors for the data bus cannot force the main processor (CPU) from the data bus until certain system conditions are met. In particular, a pattern of CPU "hits" to memory cache is recognized as an opportunity for the CPU to relinquish the data bus.

Abstract: Diskette media and drive determination mechanism in which a diskette controller attempts to read the diskette according to a variety of formats having, for instance, different data transfer rates. A successful read is registered by the controller and that format is thereafter identified with the diskette drive and the diskette media inserted in the drive.
