摘要： This disclosure relates to a method and apparatus for measuring the amount of time a personal computer system is powered on. A power on time (POT) routine is performed at a power on of the computer system. This routine sets up a timer to count the number of pre-selected time units (selected by a user) the system is powered on. The power on time count is stored in the PC's non-volatile memory. The routine sets an alarm field of the system's real time clock (RTC) to be activated after the pre-selected time unit has elapsed. A POT interrupt handler routine is installed in a chain for RTC interrupts and is invoked each time the alarm is activated (i.e., at each passage of the pre-selected time unit) while the system is powered on. When invoked, the POT interrupt handler routine increments the POT count and resets the RTC alarm to be activated after another pre-selected time unit has elapsed.

摘要： An apparatus and method for loading BIOS from a diskette drive into a personal computer system normally connected to a hardfile, such as a fixed disk. The personal computer system further includes a system processor, a random access main memory, a read only memory and a switching means. The switching means generates a signal to indicate a mode for whether BIOS loads from either diskette or disk. In a priority mode, BIOS loads immediately from diskette. In a recovery mode, BIOS loads from diskette after testing the disk subsystem.

摘要： This invention relates to personal computer systems and, more particularly, to such a system having security features enabling control over access to data retained in such a system. This invention contemplates protecting a personal computer system which has the capability of becoming a secure system from being placed into that condition by an attack on an unsecured machine. Additionally, in a network environment, it is important to maintaining network security that any given particular system be uniquely identified to the network, in order to guard against the substitution of an insecure "alternate" which would open the network to attack through an insecure system. This invention contemplates provision for such identification in a secure manner.

摘要： This invention relates to personal computer systems and in particular to an apparatus and method for loading BIOS into a personal computer system from a remote storage location. More particularly, this invention provides a personal computer adapted for use as an economical workstation in a local area network environment (a "LAN station") with provision for loading BIOS into the LAN station from a remote memory storage where the BIOS code is maintained apart from the LAN station.

摘要： Diskette media and drive determination 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.
