Due to supply constraints, early EVT systems will be deployed with the SKU206 (12V) and SKU215 (54V) variants of MGX GH200. Unfortunately, these SKUs require different flash images.

In FLM, there will be two SBIOS flash packages.

The plan of record (POR) for the program is only SKU 203/206. Until additional modules are available, the SKU215 boards will be swapped and two FLM bundles will be created.
