  • Patent number: 6996706
    Abstract: The invention provides tools and techniques for running pre-boot code on a computer from a file stored in a file system on the computer. The pre-boot code may include an operating system which is not otherwise installed on the system. For instance, the pre-boot code may be used to boot a DOS operating system on a computer which lacks a DOS hard disk partition. The pre-boot code may contain code to perform operations that are difficult to perform after the operating system is booted, such as code for monitoring the boot process to help debug it. The pre-boot code is obtained from the file without using booted file system code, and is then executed. The code may be obtained by redirecting floppy drive I/O to read the pre-boot code from a copy in memory, or to read it as needed from one or more files on the hard disk.

  • Patent number: 6666350
    Abstract: A device for separating and dispensing strips of self-adhesive articles, such as postage stamps, labels and other materials formed in strips. Elongated strips of these self-adhesive articles are wound into rolls and supported upon a waxy backing layer and require separation for use. The separating dispenser may be a two-part assembly having a housing and a closure for the housing, with a slot therethrough, which the elongated strips of self-adhesive articles are dispensed and advanced through complementary guide pins that frictionally hold the dispensed material. The device can separate a backing layer from stripped material when the backing layer and the stripped material are directed along different paths and only the backing layer is advanced through the guide pins. The mechanism of the present invention advantageously permits efficient production and operation. In addition to being economical and easy to use, this invention has obvious reliability advantages.
