When the computer boots, it will get the instructions in the boot loader, which will direct the CPU to transfer the operating system from a predetermined location into the volatile area of main memory. PostVer 0

When the machine is turned on, the CPU begins executing the bootstrap, which resides in ROM. This bootstrap directs the CPU through the process of transferring the operating system from mass storage into the volatile area of main memory. When this transfer is complete, the bootstrap directs the CPU to jump to the operating system.

At the beginning,the instructions in the boot loader direct the CPU to transfer the operating system from a predetermined location into the volatile area of main memory.Modern boot loaders can copy an operating system into main memory from a variety of locations.Once the operating system has been placed in main memory, the boot loader directs the CPU to execute a jump instruction to that area of memory.

Booting is a process of switching on the computer and starting the operating system. Six steps of the booting process are BIOS and Setup Program, The Power-On-Self-Test (POST), The Operating System Loads, System Configuration, System Utility Loads and Users Authentication. PostVer 0

When the boot program starts, it first looks for the boot line in NVRAM. If not, the contents of the NVRAM are added to the BOOT_PARAMS structure. The boot program and the VxWorks kernel then use this structure to look for the boot parameters. PostVer 0

When booting, BIOS self checks first(POST---Power On Self Test), and then looks for booting devices. There is MBR stored in a location on the hard disk. Then, start from MBR to find the system boot partition and load bootloader. After confirming booting, bootloader will give boot permissions to system files, and then load the system files into memory in a certain order, and then start the service, load boot items, and start successfully.

When booting, BIOS self checks first, and then looks for booting device. If MBR is stored in a location on the hard disk, the system boot partition will be found from MBR and the system boot will be loaded. The system boot will decide which system to boot. After confirming the startup, the system boot will give the boot permission to the system files, and then load the system files into the memory in a certain order. Then start the service, load the startup item, and start it successfully. PostVer 0

Modern boot loaders can copy an operating systems into main memory from a variety of locations. Once the operating system has been placed in main memory, the boot loader directs the CPU to execute a jump instruction to that area of memory. The overall process of executing the boot loader and thus starting the system is called booting the computer.

1. Power on;

2, BIOS Power On Self Test (post-power On Self Test), memory address is 0FFF :0000;

Read the first Sector (Boot Sector) into the memory address 0000:7c00;

4, Check (Word)0000: 7DFE is equal to 0xAA55. If not, try another medium. If there is No other boot media, it displays "No ROM Basic" and crashes.

5. Jump to 0000:7C00 to execute the program in MBR;

6, the MBR will copy itself to 0000:0600 first, and then continue execution;

Search for active partitions in the primary partition table. If there is no active partition or more than one active partition, stop;

Read the first sector of the active partition into the memory address 0000:7c00;

9. Jump to 0000:7C00 to continue to execute the startup procedure of the specific system;

10. Start the program PostVer 0

The BIOS program first loads the boot record of the storage device into memory, and then executes the boot program in the boot record;

The bootloader will load the operating system kernel in the storage device into memory and enter the entry point of the kernel to start execution

The post OS kernel completes the initialization of the system and allows users to interact with the OS PostVer 0

1. The PC power supply is ON ---- the lights on the display, keyboard, and case flash;
2. Detection screen-a short brake message appears on the screen;
3. Detect the memory-easy information of the memory appears on the screen through the beep sound;
4. Execute BIOS ---- brief BIOS information appears on the screen;
5. Detect other equipment ---- the information of other equipment appears (CPU, HDD, MEM...);
6. Execute the initialization file of OS (operating system)----start WINDOWS2000, etc. PostVer 0
