However, some users have pointed to a potential source: a download page on the Esonic Chinese domain ( esonic.cn ). One user found a BIOS file under a section labeled "H61 motherboard" on this site, though community responses suggest that official support for these legacy boards has been discontinued.

Because Esonic is a budget brand with limited official documentation, the process often mirrors that of other H61-chipset boards like those from ECS or Intel. Preparation Checklist Before starting, ensure you have the following ready: A FAT32 Formatted USB Drive
Native support for 3rd Gen Ivy Bridge (e.g., i7-3770) may require an update if the board shipped with older firmware.
