Hello. I am very new to the world of Linux, and am a Windows XP user. I have sucessfully booted Knoppix on my computer. I was just wondering:

a) What is the purpose of changing the BIOS, so Knoppix can't use the HDD? Can't Windows XP and Knoppix share the same HDD?

b) How do I change the BIOS, to fit the Knoppix recommendation?
