    When i boot up the computer it keeps saying

    invalid system disk
    Replace the disck, and then press any key

    I've tried swapping the hard drives and had the same error message. I've hitting del to get to the bios but cant.

    Without the hard disk i obvioulsy get

    Insert system diskette and press enter to reboot

    If i can get to the bios i can probably try formatting the drives. how do i do this? i cant find a manual.

    Do i need to reset the cmos? anything? any ideas?
