5.3 AUTOMATIC CPLD UPGRADE AFTER A BIOS UPDATE
During the first system bootup after you update the Flash BIOS device with the UBIOS
utility, the BIOS may need to upgrade the CPLD devices.
This message appears on the screen when the BIOS writes to the devices:
A hardware upgrade will be performed on some CPLDs. Follow the
instructions below with special care. Do not disturb the process.
DO NOT RESET OR POWER DOWN THE BOARD!!!
Device 1 0% 100%
Status :
Please wait...
The color of the boxes displayed in the message indicates these functions:
Device OK Green
Device busy Blue
Device will be updated Red
If your device upgrade was successful, the following message is displayed under the
“Status:” line prior to rebooting:
Update complete successfully, wait for the automatic reboot.
Rebooting in 5 second(s).
If the update is not successful, the following message appears under the “Status:”
line:
ERROR: general failure programming CPLDs!
Please contact Teknor Industrial Computers technical support.
You must contact TEKNOR’s technical support for further instructions.
Caution:
Whenever the BIOS performs a CPLD hardware upgrade, disable the watchdog
(by removing the W9 jumper) and do not interrupt the system in any way (power
down, reset, mouse or keyboard functions). The devices will be damaged and
your board rendered inoperative if you disturb the update process!
