Installing and Configuring the ATA/IDE Disk Chip
To ensure proper installation and of the ATA/IDE Disk Chip, follow the following configuration steps. Note that the first few steps must be performed before installing the Disk Chip.
1.Before installing the ATA/IDE Disk Chip in the Disk Chip Socket (U16), verify that cpuModule is configured for the correct Disk Chip supply voltage. The hardware default configuration is +3.3V. To use a +5 V Disk Chip with cpuModules, contact RTD Technical Support.
2.Next, apply power to the system, and press the delete key repeatedly to enter the BIOS setup screen. Once in the BIOS, specify the following settings:
a.Enable the cpuModule’s secondary IDE channel.
b.Specify the IDE mode of the ATA/IDE Disk Chip. For more information on the supported IDE modes, refer to Configuring the ATA/IDE Disk Chip Socket section of this manual on page 68.
