Help, I have an Intel desktop motherbaord with a SATA hard drive and SATA DVD. I have installed Windows XPPro on to the system and it works fine, however when I try and boot the Micro-scope CD nothing happens (blank screen) when I put the XPPro CD back in, the system ignors it and boots into Windows.

Can anybody help?

I am using an updated BIOS Intel DG43NB motherboard that gives you the option to boot from a selcted device at start up F10, the Microscope CD gives a blank screen and it ignors the XPPro CD and goes straight to startup. If I disconnect the hard drive it boots from the CD, connect it and it doesn't.
