comprehensive description of each start-up

a) pre-boot stage

press the laptop or computer energy to make the computer begins, and Windows XP Professional running system Prior to beginning this time, we name pre-boot (Pre-Boot) stage, at this stage, the laptop or computer initial runs Energy On Self Check (Publish), Post check the system's total memory as well as other hardware equipment, the position quo. If your laptop or computer system BIOS (simple input / output system) is actually a plug and play, then the laptop or computer hardware will be tested, and complete the configuration. The computer's simple input / output system (BIOS) positioning the computer's boot device, and MBR (Master Boot Report) is loaded and operate. Inside the pre-boot stage, the pc to load Windows XP's NTLDR file.
b) boot stage

Windows XP Expert boot stage consists of four tiny stage.
Very first of all, the laptop or computer has to go by means of the preliminary boot loader stage (Preliminary Boot Loader), at this stage, NTLDR personal computer microprocessors from real mode to 32-bit flat memory design. In real mode, the program is MS-DOS reserved 640kb of memory, and the remaining memory as extended memory, and within the 32-bit flat memory mode, the program (Windows XP Skilled), as all memory is readily available memory. Following, NTLDR begins the built-in mini-file program drivers, via the steps to NTLDR to identify each and every file system with NTFS or Body fat formatted partitions, to be able to discover and load Windows XP Skilled, here, in addition the first boot Uploader stage is over.
then the program came to the operating program selection phase, should the computer has more than 1 operating program (that's, multi-system), and boot.ini is about correctly choose the system below the circumstances from the operating program, computer screens operating system will show a menu, which is the result of NTLDR reads the boot.ini. (As for the operating system menu, not because of short-term circumstances, can't seize, but the writer simulated a)

within the boot.ini, primarily consist of the following:

[boot loader]

timeout = 30

default = multi (0) disk (0) rdisk (0) partition (one) WINDOWS

[operating systems]

multi (0) disk (0) rdisk (0) partition (1) WINDOWS = ) partition (2) WINNT = NTLDR will be the Windows XP Professional from right here to discover the location of program files. (* This article does not clarify in extra detail the boot.ini of the structure, since it's got small to do together with the topic, if you would like to know, can go to some specialised websites at the query specifics.) If only one operating in the boot.ini program solutions, or the timeout value is about to 0, the system doesn't seem the running system selection menu, directly in to the program or only the default system. In the choice of starting Windows XP Skilled, the running system choice stage is accomplished, the hardware detection phase begins.
the hardware detection phase, ntdetect.com will collect facts about computer hardware record and the list back again to the NTLDR, this was accomplished to facilitate later on extra to these hardware information hardware in the registry below HKEY_LOCAL_MACHINE.
hardware detection is complete, enter the configuration selections stage. In case the computer consists of several hardware profiles record, you could press the down button to select. If only 1 hardware profile, the computer screen doesn't display this directly using the default configuration file to load Windows XP Professional.
the end of the boot stage. Inside the boot stage, the program use to file a total of: NTLDR, Boot.ini, ntdetect.com, ntokrnl.exe, Ntbootdd.sys,Microsoft Office 2007, bootsect.dos (optional).
c) load the kernel stage

loading the kernel stage, ntldr load the kernel as Windows XP ntokrnl.exe. Program loaded Win
