Description Mikko Ylinen 2017-03-07 10:36:01 UTC 
It seems different BIOS versions for a board may result in different RMC fingerprints. This means the board detection will fail, e.g., if the fingerprint maintained in the database does not match with the BIOS info.

With the current design, the fingerprint-board mapping is 1:1, i.e., for each board there's only one fingerprint. Every time the fingerprint needs to change, either a new copy of the board is needed OR the old fingerprint is updated (and the old versions are no longer supported by the db).

To ease the maintenance problem, each board must be able to store multiple fingerprints (N:1 mapping).

Does not apply to RMC2. Files can be shared between platforms by creating links between fingerprint directories.
