BIOS Update Function
The SH4 CPU & .NET installed IPC series is capable of updating the BIOS when it is upgraded.
To update the BIOS, take the following steps.
1. Start the system and use CONTEC Manager to check the version of the current BIOS.
2. Copy new BIOS data to the NFDisk’s root directory.
3. Turn off the power and set the onboard DIP switch (SW2) appropriately.
Set only SW2-1 to ON and all the other bits to OFF (For details of the onboard DIP switches, refer to
Chapter 4 “On-Board DIP Switch Settings”).
4. Turn on the power again.
5. When the power is turned on, the POWER LED blinks in yellow and green at intervals of about
seven seconds.
Note : The new BIOS is being programmed into EEPROM when the POWER LED is blinking that
way.
After a while, the POWER LED blinks in green at intervals of about one second.
This state indicates that the BIOS has been reprogrammed.
6. Turn off the power and return the onboard DIP switch back to the previous states.
Set all the bits in the DIP SW2 to OFF.
7. The BIOS has now been updated completely. Recycle the power to restart the system, invoke
CONTEC Manager, and select the “Version” tab to check the version of the new BIOS.
CAUTION
The SH4 CPU & .NET installed IPC series contains the emergency BIOS for recovery in case the
BIOS fails to be reprogrammed. At worst, however, updating the BIOS still involves a risk that the
system comes to be unable to be restarted.
Use meticulous care in updating the BIOS. Never turn off the power or reset the system when the
BIOS is being updated.
