摘要： A method and system for managing cache levels based on battery backup level are described. In one embodiment, the method comprises measuring the level of charge stored in an exhaustible power source. The method further comprises monitoring the level of charge stored in the exhaustible power source. The method further comprises adjusting the storage level of the cache in response to a detected change in the level of charge. In this way, the method ensures that adequate battery power is available to transfer the contents of the cache to a non-volatile data storage medium.

摘要： A computer system program including an operating system and a plurality of system service modules generates a number of status messages representing selected milestone events while it is being loaded and run, including progress advisories and technical advisories. User-friendly icons are displayed on a display monitor in response to the progress advisories, indicating which milestone event is occurring and how much of the event has been completed. If there is a failure in loading the system program, a user can provide service personnel with an accurate evaluation of the system condition by reporting which icon was displayed last on the monitor. Technical advisories such as audit records which are not relevant to a user are stored as entries in a silent log for possible later use by service personnel. In response to a technical advisory indicating a partial or fatal load failure, a iconic or text message is displayed which instructs a user to take one or more actions, such as reporting the failure to a system administrator or service center.

摘要： A current operating system such as Solaris.RTM. X86 is adapted to run a user program such as a Common Object File Format (COFF) executable program which was designed to run on a retrograde operating system such as an older version of UNIX.RTM.. The operating system is adapted to include an emulator module or COFF interpreter which emulates retrograde system calls that are unique to the COFF system. A Local Descriptor Table (LDT) which is constructed for the COFF program includes a main system call gate and an alternate system call gate that initially both point to a system call entry point in the operating system kernel. Prior to running a COFF program, the main system call gate is revectored to point to the COFF interpreter, such that all system calls generated by the COFF program are directed to the COFF interpreter. The COFF interpreter redirects current system calls which are compatible with the current operating system to the kernel via the alternate call gate. Preferably, current system calls in a dynamic library are changed to point to the alternate call gate to minimize changes to the COFF interpreter.

摘要翻译： 诸如Solaris TM X86之类的当前操作系统适于运行诸如通用对象文件格式（COFF）可执行程序的用户程序，该可执行程序被设计为在诸如旧版本的UNIX TM的逆行操作系统上运行。 该操作系统适于包括仿真器模块或COFF解释器，其模拟COFF系统唯一的逆行系统调用。 为COFF程序构建的本地描述符表（LDT）包括主系统调用门和替代系统调用门，其最初都指向操作系统内核中的系统调用入口点。 在运行COFF程序之前，主系统调用门被指向COFF解释器，以便COFF程序产生的所有系统调用都指向COFF解释程序。 COFF解释器将通过备用呼叫门重定向与当前操作系统兼容的当前系统调用到内核。 优选地，动态库中的当前系统调用被改变以指向备用调用门，以最小化对COFF解释器的改变。
