    Also DSS V6 LITE does not have RAID Controller support - please read the link below. Only the full version does.

    Thank you for your quick reply!
    I disabled the RAID array, and set the SATA configuration to AHCI (also tried IDE)

    I tried adding "nousb2" to any and all strings in the loading screen, unforunately no luck (I assume I am supose to add a space before it, and put it at the end of the string).

    I forgot to mention this Motherboard has USB 3.0 support, which I tried disabling in the BIOS. I tried adding nousb3 to the string as well but I'm unsure if thats the correct.

    every variation, all the same result, still getting the error.

    What type of Motherboard is this and can you test with another system to make sure the USB does work?

    It is an ASUS P7H57D-V EVO

    I tested the boot media on another workstation (a Dell Optiplex 745) and it does not get the error.

    I tried disconnecting the HDDs on both the ASUS P7H and the Optiplex, Optiplex will run fine in read-only mode but the P7H still gets the error.

    It is also to go on two essentially identical P7H machines, which are both encountering the same error.

    both machines are able to navigate the initial selection menus with either a usb or PS/2 keyboard with no problems. It is just the P7H that gets the error after I select the software installer

    I tried removing the 'nousb2' string, the error still occurs, the only difference is it is displayed twice on 2 lines instead of just once, which is the similar to what happens when I tried disabling the USB controller in the BIOS.

    Something on the MB is blowing out the USB - is there any firmware updates for the motherboard - kill all pwr management features as well.

    Ive looked over the specs on this board at Asus, and it looks like a great board for a home Win7 machine with great graphics capablilities.
    With that said, I'm unsure it would make a good Linux based storage platform.
    There does seem to be a bios update for linux on this board.

    Are you using this controller:
    MarvellĀ® 88SE6111

    Marvell 88SE91xx Adapter - BIOS Version 0.0.0.1012

    Yes I noticed there have been several more recent BIOS revisions, (it is currently using rev. 0503), although I don't see anything in the revisions specifically relating the Linux. Although if flashing the BIOS is the only course of action left I'll have to get back to you on the results of that.

    another thing I just noticed, removing the nousb2 string does actually make the keyboard work after the error, as I can enter characters into the prompt right below. however if I don't remove it the keyboard no longers works. But either way the error remains.

    Thank again for the help.

    no support for this in DSS Lite that I can see.
    have you tried the full version?
