Esonic H61 Motherboard Bios Update--------

⚠️ CRITICAL WARNING:

• Updating the BIOS is inherently risky. A power failure or incorrect BIOS file during the update can permanently brick (destroy) your motherboard.
• Esonic is a budget/legacy OEM brand. Official support websites rarely exist. The correct BIOS file is often hard to find and varies by specific board revision (e.g., H61M-VS, H61L, H61 Pro, or an OEM version from Lenovo/Dell).
• Only do this if: You are experiencing a specific bug fixed by a newer BIOS, your CPU is not recognized, or you need a feature it adds. Do not update "just because."

Step 2: Check Current BIOS Version

1. Restart your PC.
2. Press F2, Del, or F10 repeatedly during boot to enter BIOS Setup.
3. Look for BIOS Version / Date (usually on the main or "System Info" tab).
4. Write it down (e.g., "4.6.5.0 09/12/2013").

Q3: Can I update the BIOS without a CPU installed?

A: No – the board must POST. For bricked recovery, you need a programmer. Esonic H61 Motherboard Bios Update--------

Method 2: Update from Windows (using AFUWIN)

Riskier – background processes can interfere. ⚠️ CRITICAL WARNING:

1. Run AFUWIN.exe as Administrator.
2. Click Load and select the BIOS file.
3. Check options: “Program all blocks”, “Main BIOS image”.
4. Click Flash.
5. Wait 1–2 minutes. Do not use the PC during flashing.
6. Reboot and load BIOS defaults.

3. AliExpress / OEM Seller Support

If you bought the board from AliExpress or a local PC shop, message the seller. Many keep internal BIOS files. Updating the BIOS is inherently risky

3. SSD & NVMe Boot Support

• Some Esonic H61 BIOS updates add support for booting from SATA III SSDs (faster than HDDs).
• Unofficial modded BIOS versions can even enable NVMe booting via a PCIe adapter.
