Nevertheless, secondary market data shows that boards carrying the /21-b6-e1-e2 stamp are overwhelmingly tied to two distinct eras of Intel personal computing: Go to product viewer dialog for this item. Intel Desktop Board 21 B6 E1 E2 ER
Use Intel® Desktop Board ID Utility or check the label on the board itself (model numbers start with D — e.g., DB65AL , DQ67SW ). The string 21 b6 e1 e2 is not a specification but a BIOS feature fingerprint.

This means that multiple distinct motherboard models (discussed below) can legitimately have this exact number printed on their board, which is why you see it associated with different specifications.
The string (often found near E210882 ) is not a specific motherboard model number but rather a series of regulatory and industry specification markings found on a wide variety of older Intel desktop boards. To find your exact specifications, you should look for the AA (Altered Assembly) number printed on a small barcode label on the board itself. The string (often found near E210882 ) is
