Computer Software System Malfunctions and Maintenance 2

The boot phase of Windows XP consists of four steps. Step 1. The initialization of the NTLDR program during boot loading will switch the processor from Real Mode to 32-bit Flat Memory Mode. In real mode, the first 640KB of memory is reserved for MS-DOS, while the remaining memory is used as extended memory, so Windows XP will not be able to use all of the physical memory. The 32-bit flat memory mode allows Windows XP to use all the memory installed on the computer (due to design reasons, the 32-bit Windows operating system can only use 2); GB, 64 bit can use 4  GB)。 Next, NTLDR starts the built-in mini file system drivers, which enable NTLDR to recognize every partition formatted with NTFS or FAT file system, in order to discover and load Windows XP.

Choosing an operating system is not necessary on a single operating system computer. If the computer is installed with more than one operating system (i.e. multiple operating systems) and boot.ini is correctly set, the computer will display an operating system option, which is the result of NTLDR reading boot.ini. The steps to set the operating system option are "System Properties" ->"Advanced" ->"Startup and Recovery", as shown in Figure 13.2.
