Possible Fault with Shogun System Management
Controller
Fault
During the production of the System Management Controller Card a small
quantity were fitted with an EPROM instead of a Flash ROM device. Thus when you try to
upgrade the BIOS on the System Management controller it will fail, because you cannot
reprogram an EPROM using a Flash Utility.
Machine affected
The faulty System Management Controller was possibly fitted into
machines before a factory purge on the 29th November 1995. Apricot are suspecting all
Shoguns prior to the purge on the 29th November.
Identification
The cards can be identified by physically checking the device or by
trying to reprogram the FPSC BIOS.
| Upgrade Identification |
| After reprogramming the FPSC BIOS SMA will report FIRMWAREUPGRADEFLAG =
FAILED or by checking the FPSC BIOS via the Front Panel, it will remain at 3.006. |
| Physical identification |
| The device (IC6) should have been a Flash device (28F010) and not a
EPROM device which fitted in error (27C010). The IC is located behind Fan 4. |
Action to take
TSD have a list of machines and serial numbers of machines that were
shipped prior to the factory purge and might have faulty System Management Controllers
fitted.
If the machine has a faulty board nothing major will happen as all
software will work with 3.006 FPSC BIOS enabling the board to be replaced at a later stage
thus enabling the new functionality of later BIOS releases.
If the board is faulty it will be exchanged by Apricot. |
