The process steps include: starting the computer system

Page 9 200404250 Power supply (step 401); when the power supply is turned on, the basic input / output system (BIOS) is turned on, and the computer host hardware is tested according to the computer booting standard procedure sa described below to perform a self-test after booting (p〇werm ^ (self-test, POST) (step 402); this BI0S is to automatically test the basic hardware components on the motherboard to see if the central processing unit (cpu), body (RAM), etc. are normal, and then to the storage device ( (Such as hard disk / soft disk), look for a bootable device. 'Detect the memory device of the present invention " wide card, and detect the memory device in which the memory card control chip is located (step 40i; then initialized). The memory card controls the chip, and the memory card (such as a read-only memory ROM) is loaded into the memory card broadcasting system and its driver to the system memory (rIm ^ step 4 04). Set the control system to log in to the file system of the card. The system that supports the memory is operated by the machine j. Is there a memory card in the system? And insert the memory card (step 405); if the memory card does not exist, remove the file system driver immediately loaded into the memory and detect other general storage and installation (step 4G7); if the memory card exists, Can you guess if the file system driver loaded with the memory device = δ Memory? Does it support the memory file system? (Step 40 6); In this step, if the loaded system driver does not support the file system of the memory card, no error message is displayed on the computer, and it is recommended to restart the computer (step 4 09); if it is in the memory card, The file system is loaded by the memory device into the system to record the file system driver to access the memory card (step 408). Finally, the memory card with the built-in operating system is booted, and its embedded open system is loaded to The system has completed the boot operation (Step 4).
