    • The invention discloses a method for preserving crash dump data in case of operating system crash in a diskless device. The method and the system according to the invention uses two stage booting where in a primary and a secondary kernel are loaded. The primary kernel is a compact kernel that comprises a limited set of functionality and the secondary kernel is a fully functional kernel used for running applications. In case of a crash of the secondary kernel, the kernel prepares a jump back to the primary kernel. Then the primary kernel preserves the crash dump support data and secondary kernel's RAM contents by sending it to a remote system which can store it on a nonvolatile memory.
    • 本发明公开了一种用于在无盘设备中操作系统崩溃的情况下保存故障转储数据的方法。 根据本发明的方法和系统使用两级引导,其中加载了主核和辅核。 主内核是一个紧凑的内核,包含一组有限的功能,第二个内核是用于运行应用程序的全功能内核。 在二级内核崩溃的情况下,内核准备跳转到主内核。 然后,主内核通过将其发送到可将其存储在非易失性存储器上的远程系统来保留故障转储支持数据和辅助内核的RAM内容。
