A. Usually, when you're prompted to press a key during Windows 2003 installation, you can press F6 to boot from the Windows 2003 CD-ROM and install an additional third-party disk controller or alternative hardware abstraction layer (HAL). If you subsequently need to install drivers or a HAL from another disk, pressing F6 again produces the following error message:
The disk you supplied does not contain relevant support files. Press any key to continue.
To avoid the error, press F6 without a disk in the drive and insert only the second disk when prompted on screen.
