There are three methods, depending on the BIOS update file you downloaded.

The Pegatron IPMSB-H61 may not be the most modern platform, but it was a workhorse in its time. A successful BIOS update can keep it running respectably for a few more years. The process is not for the faint of heart and involves risk, but with careful planning and a methodical approach, you can navigate the lack of official support and breathe new life into your old system. Good luck!
Note down whether your board is a retail Pegatron layout or a customized variant made specifically for brands like HP (often renamed as the Foxconn 2ABF or Cupertino-H61 depending on the exact contract). Step 2: Sourcing the Correct BIOS Files

You must download the correct BIOS file for your specific Pegatron board. Note: As Pegatron is an OEM manufacturer, finding official, direct downloads can be difficult. Many users find success searching for the BIOS on tech forums or sites specializing in older OEM motherboards.
Ensure you downloaded a BIOS file meant for the H61 chipset. A common issue is trying to flash a 4MB ROM onto a physical 2MB BIOS chip (or vice versa).
Find a reliable USB flash drive (8GB or smaller is ideal). Format it to the FAT32 file system. Do not use NTFS or exFAT, as the BIOS bootloader cannot read them. There are three methods, depending on the BIOS
Plug the USB drive into a rear USB 2.0 port (avoid blue USB 3.0 ports for compatibility).
Fixing "no-boot" issues with newer UEFI-based graphics cards.
You should only update the BIOS if you are experiencing a specific problem that the update explicitly solves. Do not update "just because." Common valid reasons include:
The update tool checks for a specific OEM signature. Fix: You have the wrong version (e.g., HP BIOS on an Acer board). Double-check your PC brand. A successful BIOS update can keep it running
The IPMSB-H61 is a workhorse of the 2012–2014 era, but its BIOS update process is fragile. Treat it with caution, and it will reward you with extended usability and modern OS support.
The BIOS update for a Pegatron IPMSB-H61 does come from Pegatron directly (they rarely host consumer downloads). Instead, you must download the update from the PC brand’s support page (e.g., Acer Support, HP Support).
Look for the "BIOS Version" and "VBIOS Version" in the Main menu (e.g., "4.6.5" or "1206").
Instead, consider:
Flashing the BIOS of an HP-branded IPMSB-H61 with an ASUS-branded firmware will likely brick the motherboard. Always match the "SSID" or System ID found in your current BIOS menu. Step 2: Preparation and Requirements To perform the update, you will typically need:
Look specifically for the final stable releases, often labeled as version , 0401 , or customized variants containing Ivy Bridge microcode injections.
