- TITLE :INF: Purpose of the BOOT.INI File
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- ------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- ------------------------------------------------------------------
-
- The BOOT.INI file is used by Windows NT (specifically, NTLDR) to
- determine the operating system options to display during the startup
- (boot) process. BOOT.INI is flagged as a read-only, system file by
- default and should not require any manual modification. You can change
- its contents easily from Control Panel by choosing the System icon.
-
- The following is a typical BOOT.INI file:
-
- [boot loader]
- timeout=30
- default=scsi(0)disk(0)rdisk(0)partition(1)\winnt
-
- [operating systems]
- scsi(0)disk(0)rdisk(0)partition(1)\winnt = "Windows NT" /NODEBUG
- C:\ = "Previous Operating System on C:\"
-
- The following are line-by-line explanations of the above BOOT.INI
- file:
-
- [boot loader]
- timeout = 30
-
- Timeout specifies the amount of time Windows NT waits before choosing
- the default operating system.
-
- default=scsi(0)disk(0)rdisk(0)partition(1)\winnt
-
- Default specifies the default operating system. Note: Whenever the
- operating system is Windows NT, the new storage path syntax is used.
- For more information on this syntax, query on the following words in
- the Microsoft Knowledge Base:
-
- NT and GEOMETRY
-
- [operating systems]
- scsi(0)disk(0)rdisk(0)partition(1)\winnt = "Windows NT" /NODEBUG
- C:\ = "Previous Operating System on C:\"
-
- scsi(0) means that the primary controller (usually the only one) is
- responsible for the device. If there were two SCSI cards and the disk
- was hanging off the second one, it would be called scsi(1).
-
- disk(0) refers to physical disk 1.
-
- rdisk(0) - The rdisk() parameter refers to which SCSI logical unit
- (LUN) to use, which could be a separate disk, but the vast majority of
- SCSI setups have only one LUN per SCSI ID.
-
- partition(1) in this example is the only partition on the first drive
- in the computer. If there were two partitions, C and D, C would be
- partition(1) and D would be partition(2).
-
- \winnt is the directory that multi-boot will look at to boot from one
- of the specified SCSI card's disk and partition.
-
- /NODEBUG specifies that there's no debugging information being
- monitored. Debugging information is only useful for developers and
- does slow down Windows NT somewhat.
-
- The /SOS switch can be added to display driver names while they are
- being loaded during the Windows NT boot. By default, the OS Loader
- screen only echos progress dots.
-
- The Previous Operating System on C:\ implies that it is MS-DOS,
- because "C:\" is an MS-DOS path.
