Firmware Hub (Flash BIOS)
The BIOS is stored in the 82802Ax Firmware Hub (there are second sources available with
deviant part numbers). The firmware hub contains a nonvolatile memory core based on flash
technology, allowing the BIOS to be upgraded. Currently, there are three variants of the FWH
available:
x = A: 2Mbit
x = B: 4Mbit
x = C: 8Mbit
The FWH is soldered at the bottom side of the CC8-BLUES. Be careful when upgrading to a new
BIOS - a failure while re-programming the flash (e.g. by power interruption) can cause the board
to become no more operable. You would have to send in the board to EKF for repair.
The latest CC8-BLUES BIOS release (including a suitable programming tool) is available from the
EKF website.
Programmable LED
The CC8-BLUES offers a software programmable LED, marked as IDE (placed near the reset
push-button). After system reset, this LED defaults to signal the IDE activity. By the first setting
of the GPIO22 of the ICH 82801 this LED changes its function and is then controlled only by the
level of the GPIO22 pin. Setting this pin to 1 will switch on the LED.
The LED IDE remains in the programmable state until the next system reset.
