GE90 0 0型 CT机 ,开机后即自动运行系统启动程序 ,这个过程称为 BOOT UP。其功能主要有三个 :(1)检测硬件 (包括 CP1、 MR4、 IPC、 DCU等电路板 )是否正常 ;(2 )把操作系统 (OS,即 OPERATIONSYSTEM)从硬盘调入内存(MEMORY) ;(3)把用户应用程序 (即扫描程序等 )从硬盘调入内存
GE90 0 CT machine automatically starts the system startup program after power on. This process is called BOOT UP. There are three main functions: (1) Check whether the hardware (including circuit board of CP1, MR4, IPC, DCU, etc.) is normal; (2) Transfer the operating system (OS, OPERATION SYSTEM) from the hard disk into the memory (MEMORY); (3 ) Transfer user applications (ie scanners, etc.) from the hard disk into memory
