Chapter 2 Installing CoreModule 420 Options
The procedures in this chapter describe how to install or remove the supported options onto the
CoreModule 420 single board computer (SBC). Some of the CoreModule 420 options described in this
chapter may require turning the CoreModule 420 over to install or remove the option from the
CoreModule 420.
DiskOnChip (DOC) Installation
The CoreModule 420 SBC supports the DiskOnChip by M-Systems in the bytewide socket (U5).
NOTE
The DiskOnChip is not listed as a drive and is not in the boot
order. Refer to the software instructions provided with the
specific DiskOnChip device for more information concerning
booting the device.
Tools Required
Use a complete anti-static service kit (or the equivalent) to remove or install the DiskOnChip onto the
CoreModule 420. A complete anti-static service kit should include a static-dissipating work surface, a
chassis clip lead, and a wrist or ankle strap.
Installing the DiskOnChip (DOC)
CAUTION
To prevent damage to the CoreModule 420 or the DiskOnChip, ensure the power
supply to the CoreModule 420 is turned off and the power cord has been removed
from the power source. Most AT power supplies will continue to provide standby
current to the CoreModule 420 until the power cord is disconnected.
1. If the CoreModule 420 SBC is already powered up, power down the system and remove the
power cord from the power supply.
CAUTION
To prevent damage to the static sensitive components on the CoreModule 420,
ensure you follow good Electrostatic Discharge principles. The CoreModule 420
and the DiskOnChip are sensitive to static electricity and can be easily damaged
by improper handling. Do the following when handling the CoreModule 420 and
its related DiskOnChip:
Always use an anti-static wrist/ankle strap and a grounding mat.
Before you handle the CoreModule 420 or remove the DiskOnChip from the anti-
static bag, touch a grounded, unpainted metal surface to discharge any static
electricity.
2. Verify the bytewide socket (U5) pins are clear of any material or obstructions that would prevent
installation or bend the DiskOnChip pins.
