Rear Transition Module
5-7
IDE1 Connector
IDE1 connects up to two hard drives, primary master and slave. Power for the drives is
not supplied by the XVME 990-VR7.

Caution
It is recommended that only an 80-conductor, 40-pin EIDE cable is used
with the XVME 689-VR7. This cable type has additional ground planes
that can handle the faster interface speeds. Intermitted hard drive
functions can be traced back to the use of a standard 40-conductor, 40-
pin cable.
The IDE controller supports enhanced PIO modes, which reduce the
cycle times for 16-bit data transfers to the hard drive. Check with your
drive manual to see if the drive you are using supports these modes. The
higher the PIO mode, the shorter the cycle time. As the IDE cable length
increases, this reduced cycle time can lead to erratic operation. As a
result, it is in your best interest to keep the IDE cable as short as
possible.
The PIO modes can be selected in the BIOS setup (see p. Error!
Bookmark not defined.). The Auto configuration will attempt to
classify the connected drive if the drive supports the auto ID command.
If you experience problems, change the
