SING THE UTILITYMODULE
IDE Hard Disk
The CMT106 provides an IDE interface to 2.5 inch, 2.1 Gbyte harddrive. This harddrive can be
set up as the primary or the secondary drive (you must be sure that your CPU bios supports both
primary and secondary drives). The CMT106 cannot be used as a slave drive.
Since the CMT106 provides the IDE decoding on-board, there is no need for any cabling. You
must be sure to disable any other IDE controllers that might be present on your CPU module or
VGA module.
You may need to run the setup program for your cpuModule or computer to configure the correct
hard drive type.
NOTE: If you are using this harddrive with an RTD CPU module, enter 4095
for the number of cylinders.
