Just a suggestion, I have a computer at work that the DVD drive is configured as Master and the CD burner is Slave. Since the computer is shared and not mine I decided not to change anything. However, when I turn my Primary/Master (DVD) drive off in the BIOS the PC will boot from the Secondary/Slave (CD Burner) drive. After my Knoppix CD boots, Knoppix sees both CD and DVD drive (since it does not take the BIOS setting as serious as Windows does). This allows me to use whichever drive I wish using the BIOS setting like a switch. The only problem I have is when I forget to turn both drives back on in the BIOS, the poor Windows users whine because they have one drive that does not get detected.
