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.
摘要翻译：本公开涉及一种用于测量个人计算机系统通电的时间量的方法和装置。在计算机系统的电源接通时执行通电时间（POT）例程。该例程设置一个计时器来计算系统上电的预选时间单位数（由用户选择）。上电时间计数存储在PC的非易失性存储器中。该程序设置系统的实时时钟（RTC）的警报字段，以在预先选定的时间单位过去后激活。 POT中断处理程序例程安装在用于RTC中断的链中，并且在系统通电时每次激活警报（即，在预选时间单元的每次通过时）被调用。当调用时，POT中断处理程序例程增加POT计数，并将RTC报警复位为在另一个预先选定的时间单位过去后激活。

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.
摘要翻译：一种用于将BIOS从软盘驱动器加载到通常连接到诸如固定盘之类的硬文件的个人计算机系统的装置和方法。个人计算机系统还包括系统处理器，随机存取主存储器，只读存储器和切换装置。切换装置产生一个信号，指示是否从软盘或磁盘加载BIOS的模式。在优先模式下，BIOS会立即从软盘加载。在恢复模式下，BIOS在测试磁盘子系统后从磁盘加载。

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.
摘要翻译：软盘介质和驱动器确定，其中软盘控制器尝试根据具有例如不同数据传输速率的各种格式来读取软盘。控制器注册了一个成功的读取，然后用软盘驱动器和插入驱动器中的软盘介质来识别该格式。
