摘要： A computer system and method that are useful for embedded operating systems, thin client computing applications and the like, protects memory blocks in a nonvolatile version of the system program used at startup (reboot), for example in flash memory. Write operations to protected memory blocks are intercepted. A potentially revised version of any attempted re-written block is maintained in RAM and can be revised further during runtime, the original protected block remaining unwritten. A restriction process flags when or whether a revised block in the RAM is to become permanent. During a write operation or at orderly system shutdown, the revised blocks that were marked are written over the protected blocks in the nonvolatile version. The process can be embodied using file and directory attributes in variably sized Ramdisk virtual drive in a Windows XP-embedded system, providing processes with read access to the original protected block as well as the revisions, enabling configuration changes and software installations without multiple reboots.
摘要翻译：对嵌入式操作系统，瘦客户端计算应用程序等有用的计算机系统和方法保护例如在闪速存储器中启动（重启）时使用的系统程序的非易失性版本中的存储器块。对受保护的内存块的写操作被截取。任何尝试重新写入的块的潜在修订版本保留在RAM中，并且可以在运行时进一步修改，原始保护块保留未写。限制过程标记RAM中的修改后的块是否变为永久性。在写操作或有序的系统关机期间，被修改的块被写在非易失性版本中的受保护块上。该过程可以在Windows XP嵌入式系统中使用可变大小的Ramdisk虚拟驱动器中的文件和目录属性来实现，从而提供具有对原始受保护块的读取访问权限以及修订版本的进程，从而实现配置更改和软件安装，而无需多次重新启动。
