<Appendix> Assist Mode
This equipment has the Assist Mode to enable the following functions.
(1) NVRAM flag clearing (“Clear NvRAM flags.”)
Even if the firmware downloading has been completed normally, the Recovery Mode may
accidentally start up when the power is turned ON again. In this case, clear the NVRAM flags used
in the download process with this function.
(Normally, the flags are automatically cleared in the download process.)
Also in the case the Recovery Mode accidentally starts up after the replacement of NVRAM on the
SYS board, the flags are cleared with this function.
(2) Data storage partition formatting (“Format UID rom PRF PR2 SMS Partition.”)
When a defection occurs on the UI data, etc. which are stored in the HDD, the partition with the
stored UI data, etc. is formatted with this function.
(Do not use this function since it is not normally necessary.)
(3) HDD partition creation (“All Partition delete and create UID rom PRF PR2 SMS Partition.”)
When the HDD is replaced or UI data, etc. are downloaded using the FSMS or USB storage, it is
necessary to format a partition in the HDD before downloading. In this case, the partition is
created in the HDD with this function.
Notes:
1. When downloading with a download jig, it is not necessary to format a partition in advance.
2. Perform the HDD partition formatting only when a new HDD and scrambler board are installed
since all data in the current HDD are erased by this operation.
