I can't get it to boot from the CD I have,I changed the bios and moved the CD drive to the top,but no luck.If I try to boot with just the CD I get the invalid disc message and have to boot from the ME boot floppy which puts me in a command prompt window.Can I type a command to run the CD and if so,what.

I have 2 other CD's I can try when I get home ,but none of them are factory.
