PX-712 Installation and Users Manual
Identifying Whether Your System Uses Cable
Select
If you are unsure whether or not your system has a Cable Select cable
installed, either look at the cable (see the illustration on page 27) or look
at the jumpers on the DVD-ROM or CD-ROM drive. If any device is
jumpered as Cable Select, then both devices on that cable should be
jumpered the same.
Locating the Master Position on a Cable Select
Cable
With Cable Select, Master and Slave are determined not by jumpers, but
by the connectors on the Cable Select cable. The connectors are
identified as Master or Slave.
Set the DMA Jumper
Your PX-712A ships from the factory with no DMA jumper installed.
(The pins are empty.) The empty pins mean the drive is set to Ultra
DMA. This setting should work in most cases, so you don’t have to do
anything more.
With some personal computers (usually older ones) that do not have an
Ultra DMA IDE chipset, the computer may “hang” or crash with the
PX-712A set to the default Ultra DMA setting. If this happens, change
the PX-712A to Multiword DMA mode by installing the spare jumper
across the two DMA jumper pins just to the left of the mode jumper
pins.
