, designed for Windows 7 and older 32-bit/64-bit architectures. Key Technical Specifications
This is the vendor identifier block. Every network-enabled component built by Intel Corporate utilizes an OUI registration prefix. A network interface controller (NIC) reading this prefix flags the hardware explicitly as an Intel device.
Early memory detection Meaning: Code 21 indicates the BIOS is waking up the memory controller (traditionally on the Northbridge chipset) and beginning to sense if RAM modules are present. This is before SPD reading or timing training.
The identifier "01 21 B6 E1 E2 ER" refers to a regulatory or manufacturing code found on certain legacy Intel desktop boards rather than a specific commercial model name intel desktop board 01 21 b6 e1 e2 er
These numbers usually denote the hardware revision and the specific production batch. A higher number typically implies a later revision of the board (addressing initial bugs or manufacturing updates).
A cluster of SATA ports (supporting standard 3Gbps and 6Gbps speeds) nestled along the bottom-right edge for seamless drive routing. Hardware Architecture & Technical Specifications
Based on secondhand hardware listings and archived community forums, motherboards branded with these factory codes share several very specific physical characteristics: LGA 1155 (Socket H2) , designed for Windows 7 and older 32-bit/64-bit
. Common features associated with boards using this identifier include: Processor Support
Different boards sharing these markings may support different RAM types (though most are DDR3 ) and have different form factors, typically Micro-ATX or ATX .
Official support from Intel has largely ceased, but drivers can sometimes be found via Intel's Support Site by searching for the specific model number (e.g., DQ67SW or DH61BE) rather than the manufacturing string. A network interface controller (NIC) reading this prefix
While many users mistake this for the primary model number, it is actually a compliance or revision-related code often found on stickers near the I/O ports or PCIe slots. Socket Support : Frequently associated with the socket (Socket H2), which supports 2nd and 3rd Generation Intel Core processors (e.g., i7-2600, i5-2300). Primary Models : The code is frequently seen on boards like the Intel D2500CC (an industrial Atom-based board) and some versions of the Intel DH61 System Era : These boards typically date back to approximately 2011–2013
Intel consumer boards use names like DH61HO , DH67BL , DQ67SW , or DZ68DB .
: LGA 1155, which supports 2nd and 3rd Generation Intel Core processors (e.g., i7-2600, i5-3470).
