But this one survived. It was "New."
In other words, these markings certify that the motherboard meets specific safety, environmental, and electromagnetic compatibility standards required for sale in different regions. They have nothing to do with the board's model name, chipset, or supported components.
The designation refers to a UL (Underwriters Laboratories) stamp found on several different Intel desktop motherboard models produced between roughly 2004 and 2010. The alphanumeric code (often listed as 21 b6 e1 e2 er in listings) is a manufacturer identifier.
Based on technical data for boards bearing this identifier (such as the Intel D865GVHZ or similar legacy models), here are the key features: Core Specifications

Therefore, if you have a board with these markings, there is a very high probability it is an .
While retail consumers typically search for boards by their commercial product name (e.g., Intel DH61WW or D865PERL), industrial suppliers and IT departments catalog components using the precise silkscreened codes found on the PCB. Socket and CPU Compatibility
: Typically include one PCIe x16 slot for graphics cards and several PCIe x1 or legacy PCI slots.
Board powers on, fans spin, but no video. Diagnostic LED shows "E1". Fix: But this one survived
If you can boot into your operating system, free software tools can instantly identify your hardware. Programs like CPU-Z, Speccy, or HWiNFO will report the motherboard manufacturer and the exact model number.
: Compatible with Intel Pentium 4 processors featuring Hyper-Threading Technology for improved multitasking.
When you first turn on your computer, press the key to bypass the Intel logo screen if it appears. You will see a BIOS identification string near the top left corner of the screen. Recent Intel Desktop Boards use an Intel/AMI (American Megatrends) BIOS core with strings that look like:
Yes, but only to collectors of Intel prototype hardware or those reverse-engineering Intel’s firmware. For a normal PC build, an "ER New" board is a risk – it might reject retail CPUs, have non-final voltage regulators, or lack certain PCIe lanes. The designation refers to a UL (Underwriters Laboratories)
: Could range from H series (e.g., H410, H470), B series (e.g., B360, B460), Z series (e.g., Z390, Z490), or others, each offering different features like overclocking capabilities, number of USB ports, SATA ports, etc.
Typically LGA 1155 (2nd/3rd Gen Core) or LGA 1150 (4th Gen) variants Dual-channel DDR3 SDRAM slots Expansion Capabilities 1 x PCI Express x16 slot (dedicated GPU support) Storage Interfaces Multiple SATA III and SATA II headers Rear I/O Connectivity USB 3.0, USB 2.0, Ethernet (RJ-45), VGA, and HD Audio Why Settle for a "New" Legacy Intel Board?
If using a 2-digit LED debug card:
, you are likely dealing with an older, often refurbished or "New Old Stock" Intel desktop board. These specific identifiers are frequently associated with the Intel E210882
