A Discussion About the Bootcfg Command and Its Uses
Microsoft Knowledge Base Article: 291980 - This article discusses the bootcfg command and its uses. The bootcfg command is a Windows XP and Whistler Recovery Console command that manipulates the Boot.ini file. This command has a function that can scan your hard disks for Microsoft Windows NT, Microsoft Windows 2000, and Microsoft Windows XP installations, and then add them to an existing Boot.ini file or rebuild a new Boot.ini file, if one does not exist. The bootcfg command enables additional Boot.ini file parameters to be added to existing or new entries.

Purpose of the BOOT.INI File
Microsoft Knowledge Base Article: 99743 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.

Windows NT© and the BOOT.INI
This document explains how to modify NT©s Boot.ini to correctly reflect the location of the NT partition. The Boot.ini file will incorrectly reflect the location of the NT partition if you use PartitionMagic?s Copy feature to copy an NT partition or if you use Drive Image to copy a partition. In these cases, the Boot.ini will reflect the position of the original partition and need to be updated to reflect the new position. Source: PowerQuest

How to Articles

How to Disable Detection of Devices on Serial Ports
Microsoft Knowledge Base Article: 131976 Explains how to modify the Boot.ini file to disable the detection of devices on COM ports. When you start Windows NT, NTDETECT searches for the pointing device (usually a mouse). In the course of this process, data is sent to the serial (COM) ports. If a serial mouse is detected, Windows NT disables the port so a device driver for the mouse can load instead. If a device is not detected, Windows NT disables the port. A disabled COM port does not display any information in Control Panel Ports.
