    yes its ide though its an older 1 ghz celeron everything is hooked up correctly new battery power supply registers 4. 97 v im lost on any ways to check the mother board also there was a mouse living in it while it was in storage i took it apart everything but jumpers dont know if problem was present before but after it gave cmos checksum error so i reset it and no drives are found except A drive
  3. so the hard drives are IDE and connected with 40 [ or 80 ] wire ribbon cables?

    Check the JUMPERS
    Put the Hard drive on the end of the cable with the jumper set to MASTER

    The CD should be on the center connector , or another IDE channel , and set to SLAVE
