Given the common appearance of this marking and its frequent mention alongside the code, your "21 b6 e1 e2" board is highly likely to be the . This was a popular micro-ATX board from the LGA775 era designed for budget-conscious yet capable systems. It was optimized for "Green PC" builds due to its support for 95W TDP processors, balancing cost and performance.
The most common desktop boards found in secondary markets under the "21 B6 E1 E2" umbrella are built on the socket architecture. These are highly reliable, industrial-grade micro-ATX or ATX boards frequently extracted from corporate workstations. 3rd-gen-core-desktop-vol-1-datasheet.pdf - Intel
The board’s capacitors began to whine. The CPU fan spun to 100%. On screen, a memory map unspooled: 0x21B6, 0xE1, 0xE2… then a file listing from an unmapped region of the BIOS: intel desktop board 21 b6 e1 e2 specification
