I/O failure

[Newguy2]

Hi guys,
I bought a abit board listed as working in the hardware list.  I tried using a usb gigabit adapter that I previously had working out of the box with linuxmce on another mainboard.  When doing the DVD install I got the error message "i/o failure" in several attempts to do a fresh install. I decided to try a linksys gigabit adapter and got the same error message.  Everything installs ok once i don;t have another NIC in.  Any suggestions? Bios maybe?
