Interpretation Boot.ini
(Author: Jing-positive in 2001 at 11:01 on February 16)
Sometimes we have a multi-operating system on your computer, such as Win 98, Win NT Server 4.0, and Win 2000 Professional Triple Operation System, with a view to give full play to their respective potential, and make long-term additions. After the installation is complete, we can discover the files named boot.ini under the root directory of the system partition (generally c: /). For example, to install the above three operating systems, it is usually installed in accordance with WIN 98 → WIN NT Server 4.0 → Win 2000 Professional, in fact, this file is established when you install WIN NT Server 4.0. This is a read-only system configuration file that can be loaded while launching the selection menu, allowing us to choose a different operating system to start. The following content is the typical setting of the file, let us interpret it! [boot loader] timeout = 30 default = MULTI (0) DISK (0) RDisk (0) Partition (4) / Winnt [Operating Systems] Multi (0) Disk (0) RDisk (0) Partition (4) / Winnt = "Microsoft Windows 2000 Professional" / FastDetect Multi (0) Disk (0) RDisk (0) Partition (1) / WinNT = "Windows NT Server Version 4.00" Multi (0) DISK (0) RDisk (0) Partition (1) / Winnt = "Windows NT Server Version 4.00 [VGA Mode]" / Basevideo / Sos C: / = "Microsoft Windows" file is divided into two blocks of boot loader and operating system systems. In the boot loaded portion, timeout = XX means waiting for the user to select the operating system, the default is 30 seconds; default = xxxxx indicates the system path to the system to load by default, when the system is waiting to wait for the user to choose the highlight section. In the operating system part, all operating system paths and a list are listed for user selection. At this point, we have a preliminary understanding of the general framework of the document. But what is the representative of "Multi / SCSI (X) Disk (X) RDisk (x) Partition (X)"? This requires us to understand the ARC (Advanced RISC computer) named, which is a dynamic method for identifying the device in the X86 or RISC computer. Figure 1 ARC named first part is used to identify hardware adapter card / disk controllers, which have two options: SCSI and Multi. Multi represents a non-SCSI hard disk or a SCSI hard disk accessed by SCSI BIOS, while SCSI represents a SCSI BIOS prohibited SCSI hard disk; (x) is hardware adapter card number; Disk (x) means SCSI bus number, ie if hardware The adapter card is MULTI, and its correct representation is Disk (0); RDisk (x) represents the serial number of the hard disk, that is, if the hardware adapter card is ignored; Partition (X) represents the partition number of the hard disk. In this way, it can be expressed in Figure 1, Figure 2. So, we can understand the specific meaning of various settings in Boot.ini. Figure 2 In addition, we have found options such as / basevideo, / sos, / fastdect, all of which are switched characters.
