While "Intel Desktop Board" is the product line, the string 01 21 B6 E1 E2 does not correspond to a standard commercial model name (like "DQ67OW" or "DH67BL"). Instead, this string is characteristic of or SMBus Device IDs found in hardware documentation.
If you own this board and are seeing 01 21 b6 e1 e2 er during boot failure → first. If you’re documenting this string for a database → It’s likely a manufacturing identifier (less useful for repair). If it’s an error code → It is not a standard Intel POST code ; check your manual for your specific board series (e.g., DQ67SW, DZ77BH, etc.).
The CPU socket is located on the top-left side of the motherboard, with the chipset and memory slots nearby. The expansion slots, including the PCIe x16 slot, are located on the bottom-right side of the motherboard. The storage ports, including the SATA and mSATA ports, are located on the bottom-left side of the motherboard. intel desktop board 01 21 b6 e1 e2 er
The keyword represents a specific string of regulatory, regulatory compliance, or manufacturing markings (often associated with marking combinations like E210882 or industrial board layouts) found on older Intel desktop motherboards. These boards are typically designed for LGA 1155 sockets supporting Sandy Bridge or Ivy Bridge (2nd and 3rd Generation Intel Core) processors , though variations extend into older legacy architectures.
Your sequence 01 21 b6 e1 e2 er looks like a with er possibly standing for “Error” on a 2-character LED (e.g., Er shown as Er or E2 ). While "Intel Desktop Board" is the product line,
System Management Bus (SMBus) setup Meaning: E1 is an OEM-specific code (not standard Phoenix or Award). On Intel boards, E1 usually corresponds to initializing the SMBus, which communicates with voltage regulators, thermal sensors, and RAM SPD EEPROMs. A hang at E1 points to a short on the SMBus clock or data line.
