W2600CR2 has two SKUs, W2600CR2 (normal SKU) and W2600CR2L (Lite SKU). The only difference is that the Lite SKU doesn't have I/O module slot, and it was only available for a limited time. Both SKUs use same BIOS package.
Your PBA# indicates your board is normal SKU. However, it seems it's an early pre-production board. What is your current BIOS version?
Thank you edwardzh for your help,
If I understand correct, that only way to flash the bios its via recovery mode or via jtag.
Since that I can flash BMC in regular mode and BNC working well after it, I guess that production bios will work.
1. or where I can find rml.rom for my current bios for recovery options
2. where I can find jtag interface scheme for connection and what type of bios chip inside?
Can you help me with it please
