Manual Update Process

Step 2: Find the Correct BIOS Update

1. Identification: The user must first verify the exact motherboard model (B36H4-AD) and the current BIOS version via the System Information tool (msinfo32) in Windows.
2. Acquisition: Next, the user navigates to Acer’s official support website, enters the desktop’s serial number (SNID), and locates the “BIOS/Firmware” section. Unlike retail boards, Acer distributes updates as a single executable (.exe) file packaged within a ZIP folder.
3. Preparation: A USB flash drive formatted to FAT32 is required, as the motherboard’s UEFI shell reads this file system reliably. The user must extract the BIOS file and the flashing utility (often named “AFUWIN.exe” or a similar Acer-specific tool) onto the drive.
4. Execution: The user reboots, enters the BIOS by pressing F2 or Del during startup, and disables Secure Boot temporarily. The update is then launched either from a bootable DOS environment or directly via the UEFI’s built-in flashing tool (typically by pressing F7 or selecting “Flash BIOS”). A critical manual step is renaming the firmware file to a specific Acer convention (e.g., “BIOS.cap”), which the board’s recovery routine expects.
