系统文件

LPC2148 of ARM7-TDMI configuration was adopted as main controlling chip, and its software design was completed by multitask scheduler based on UCOS-Ⅱ, while the FAT system controlled the read-write to the files in SD card. The signal emergence, change in hearing class, frequency selection as well as records of subject reaction were automatically achieved.

系统采用了ARM7-TDMI架构的LPC2148为主控芯片，软件设计上采用了基于UCOS-Ⅱ的多任务调度机制，以FAT文件系统的方式对SD卡的文件进行读写操作，信号的出现、听力级的改变、频率的选择以及受试者反应的记录均由系统自动完成，自动实现听力损伤评级。

The basic organization of the UNIX filesystem, the idea of using a user process for the command interpreter, the general organization of the filesystem interface, and many other system characteristics come directly from Multics.

到这里，就已经将原先的windows的E盘（2501到5000柱面），那个/dev/sda6分成了三个区。现在如果保存分区操作后，再使用格式化工具创建文件系统后，原先的 2501到5000柱面上的数据将丢失。当然，我们不必担心，因为事先已经将文件复制到了其它的地方了。注意：现在有一个问题，看上面/dev/sda11 的尾柱面是 5000 ，而/dev/sda6的首柱面是5001 。一直到/dev/sda8 的首柱面都位于/dev/sda11的尾柱面之后。也就是说它们的物理位置在后面，但分区编号在前面。为改变这一状况，有一个简易的方法。就是先删紧靠 5000柱面之后的一个分区，然后立即按默认首柱面和尾柱面进行分配，在重建分区表的时候注意把分区的系统标识也改也原先的（因为 Linux的fdisk中默认的新建的分区系统标识为id为83。

CMDS-MSS是在服务器的文件系统之下、设备驱动程序之上采用虚拟技术实现存储空间的单一逻辑视图的一种方案，它既保持了对现有应用和体系结构的兼容性，同时又可充分利用文件系统的块缓冲区来提高系统的性能。

Windows9x series using a FAT file system, due to the form of links, at the beginning of the beginning of the various sectors of documents stored in a row, but with the additional documentation to establish, delete and other operations, the newly created file on the beginning of the distribution of in non-consecutive disk sectors, the middle of the distribution sector there are other documents and / or space sector.

Windows9x系列用的是FAT文件系统，由于采用链接表的形式，在刚开始的时候文件的各个扇区是连续存放的，但随着更多文件建立、删除等操作，新建立的文件就开始分布于不连续的磁盘扇区，中间分布有其它文件的扇区和/或空扇区。
